Purpose: To evaluate the dimensional accuracy of implant impressions obtained using five different tray types and two techniques. Materials and Methods: A partially dentate maxillary Kennedy Class II model was created as a reference model through 3D printing. Then, implant analogs 4.3 mm in diameter were placed at the first premolar, first molar, and second molar sites. Five types of trays were used to create impressions: (1) metal stock trays, (2) plastic stock trays, (3) custom trays fabricated using liquid crystal display (LCD), (4) custom trays fabricated using fused deposition modeling (FDM), and (5) custom trays fabricated using urethane dimethacrylate (UDMA) resin. Open and closed tray techniques were also compared. In total, 150 impressions were obtained. The reference model and impressions were scanned using a laboratory scanner. Additionally, the positional and angular deviations of implants with different tray types and techniques were evaluated using the superimposition method. Results: There was no statistically significant difference (P > .05) between the impression accuracy with the different tray types and impression techniques. The angular deviations with plastic and UDMA trays were greater than those with metal, FDM, and LCD trays. Angular deviation at the second molar was greater when using closed plastic trays compared to open plastic trays. The highest and lowest positional deviations were observed at the first molar implant with an open plastic tray impression (mean ± SD of 62.46 ± 28.54 mm) and a closed LCD tray impression (36.59 ± 29.93 mm). The greatest angular deviation was observed with an open FDM tray impression at the first premolar implant (0.067 ± 0.024 degree), and the lowest angular deviation was observed with a closed metal stock tray impression at the second molar implant (0.039 ± 0.025 degree). Statistical differences were detected using the Mann-Whitney U test for paired groups and the Kruskal-Wallis test for groups with more than three comparisons (P > .05). Conclusions: Plastic and metal stock trays or conventional and 3D-printed custom trays can be used to obtain implant impressions for maxillary partially edentulous arches with similar dimensional accuracy. The five tray types and two techniques may be safely used to obtain impressions of partially edentulous maxillary arches with three implants. [ABSTRACT FROM AUTHOR]

Introduction: In every prosthetic treatment, the final purpose of the restoration is to restore function and esthetics for the patient, respecting biology and anatomical parameters. Regarding full coverage restorations, there are some factors to take into consideration: like the finish line (chamfer, shoulder, featheredge, etc.), the management of the provisional restoration and tissue healing, the material for the final restoration, and the impression technique. All these aspects will determine the treatment process and its possible results. In recent years, vertical preparation and more specifically biologically oriented preparation technique has generated great interest since its introduction in prosthodontics, changing the periodontal tissues, and providing long‐term stability. Materials and Methods: With this technique, the objective is to change the position of the gingival margin, moving it more apically or coronally, depending on the modifications of the provisional. The relining of the provisional is a fundamental step of this technique: the intrasulcular part of the provisional is modified giving a new emergence profile and providing an augmentation of the tissue in the healing process. Discussion: In vertical preparation, there is no predetermined margin. The dental technician should position the finish line more apically or coronally, depending on the depth of the sulcus and on the esthetic needs. Ceramic restorations should not invade the epithelial attachment, otherwise it may cause biological and mechanical problems, repetition of the impression, and of the crown restoration, which lead to increased clinical and laboratory time usage as well as expenses. One challenge is communicating the shape and contour of the temporary restoration to the dental lab to ensure accurate information for the final restoration. Conclusion: Finally, the objective of this article is to describe a technique for transferring all necessary information of the provisional and obtaining a predictable result for the final restoration by using an intraoral scanner system and the fabrication of two 3D printed prototypes. One for the final volume of the crowns and the other for the finish line position. Clinical Significance: The fabrication of 3D printed prototypes allows for a more predictable final restoration, reducing possible communication errors between clinician and technician when restoring with biologically oriented preparation technique. In any esthetic treatment where the restoration does not have a predetermined margin, it is possible with this additional clinical step to provide a more esthetic outcome. [ABSTRACT FROM AUTHOR]

Introduction: The use of digital dentistry is rapidly increasing in prosthodontics. However, most dental students are not familiar with applying digital technologies in dental clinics. Thus, the aim of the current study was to assess the perception of dental students at different educational years towards digital impressions in comparison to conventional impressions. Materials and Methods: A cross‐sectional questionnaire‐based study was conducted on various educational years of dental students in the College of Dentistry, Imam Abdulrahman Bin Faisal University, between February and April 2023. The students had performed at least one intraoral scan (Trios 3shape) and another conventional polyether impression for phantom casts/patients. The questionnaire assessed students' perceptions of digital impressions using a 5‐point scale ranging from strongly agree to strongly disagree. Mann–Whitney U and Kruskal–Wallis tests were used to compare students' perceptions of digital impressions according to gender and educational year, respectively. Results: The study included 122 students. About 55% were females with a mean (SD) age = 22.51 (3.36). Most students thought that digital impressions are faster and more user‐friendly compared to conventional impressions. Significantly more female students thought that the handpiece was too big for intraoral use (p = 0.04) and that the process of the software was time‐consuming and complicated. In general, higher educational year students were more satisfied with the digital impressions than lower educational year students. Conclusions: Digital impressions were perceived by most students as being faster and easier than conventional ones. However, male students and those with higher educational years showed better perception of digital impression. [ABSTRACT FROM AUTHOR]

Objective: This study investigated how the number of images collected for digital measurements in dentistry affects accuracy compared with traditional methods. Methods: A Frasaco maxillary model was scanned using a SHINING 3D AutoScan-DS-MIX dental 3D scanner to create an STL file. The maxilla was molded 10 times using polyvinyl siloxane (Zhermack Elite HD+) to produce plaster models, which were scanned with the same reference scanner to generate 10 STL files. The Frasaco model was scanned 10 times, capturing images in intervals of 800–1000, 1000–1200, and 1200–1500 using a 3Shape TRIOS 3 intraoral scanner, creating additional STL files. These were analyzed with reverse engineering software. Results: The most accurate measurements were obtained using 1200–1500 images. Conventional impression techniques performed significantly worse. There was a significant difference between the groups Digital 1200–1500 and Plaster (p < 0.001) and between Digital 800–1000 and Plaster (p = 0.007). No significant difference was found when the digital groups were compared among themselves. There was also no significant difference between the Plaster and Digital 1000–1200 groups. To compare precision values that were normally distributed across three or more methods, a one-way ANOVA was used. Trueness values that were not normally distributed with three or more methods were compared employing the Kruskal–Wallis test. Conclusions: Different image counts affect digital measurement accuracy. The most accurate measurements were obtained when collecting 1200–1500 images. Conventional impression techniques were shown to perform significantly worse than digital impression.

An esthetic peri‐implant soft tissue contour is a critical element of the success of implant restorations in the esthetic zone. Once the optimal transmucosal soft tissue profile is formed, it needs to be accurately replicated on the master cast. This clinical technique involves the utilization of a silicone putty positioning index placed in the patient's mouth to accurately duplicate the external contour of teeth and soft tissue. By combining this positioning index with the implant‐supported interim crown, the 3D‐printed initial cast, which was used to fabricate the interim crown, can be conveniently and efficiently transformed into a definitive master cast.

Purpose – The study aims to determine whether a relationship exists between the potential significance of corporate controversies for stakeholders and how organisations respond to them in their annual and sustainability reports. Design/methodology/approach – This paper employs content analysis on annual and sustainability reports of 48 listed companies from the Refinitiv database. The logit regression was used to estimate the model. Findings – The study revealed that the main factors increasing the probability of a controversial issue being addressed in a corporate report are the controversy’s potential significance, companies’ financial performance and lawsuits. Research limitations/implications – Our study has three major limitations. These are a relatively small sample of companies and reports, focusing on disclosures made in corporate reports and omitting other channels of communication, for example, social media, and a certain amount of subjectivity in the process of coding information. Social implications – Former studies show that corporations face a serious risk of their hypocritical strategies becoming too evident for stakeholder groups. Our findings suggest that the risk is already materialising and may undermine the idea of CSR and sustainability reporting. Originality/value – Our research focuses on high-profile adverse incidents widely reported in the media, the omission of which from corporate reports seems to constitute a particular case of organised hypocrite. It also demonstrates that companies use an impression management strategy to defuse adverse publicity and that major controversies cause minor ones to be omitted from their reports.

Purpose: To compare the quality of complete dentures and quality of life of participants rehabilitated by using TENS (Transcutaneous electric nerve stimulation) facilitated impression making with manual impressions. Material and methods: Ten completely edentulous participants were enrolled in the crossover, pilot study. Participants were randomized in 2 groups. Five participants in each group were rehabilitated by dentures fabricated with TENS facilitated definitive impression technique (group T) and conventional impression technique (group C). In group T, Bioelectric border molding was done for the participants, that uses electric stimulation of the nerves supplying the muscles. In group C, incremental border molding using modeling plastic impression compound was carried out. Participants in each group used the dentures for 3 months. After 3 months, OHIP-EDENT questionnaire responses were obtained from the participants to observe the oral health related quality of life. A dental specialist recorded denture quality by Kapur scoring criteria. After one month wash period, the treatment was swapped between the groups. OHIP-EDENT scores and Kapur score were recorded for the alternate dentures after 3 months of use. Descriptive analysis was followed by Mann Whitney test to compare the overall scores between group T and group C for OHIP-EDENT, the scores for individual domains of OHIP-EDENT, and Kapur score for denture evaluation (α = 0.05). Results: The overall OHIP-EDENT scores within each domain were less in group T when compared with the scores in group C and Kapur score for group T was more than group C. The difference was statistically significant i.e. P = 0.002 & 0.003 respectively. Conclusions: Less OHIP-EDENT scores in group T imply better perception of quality of life of individuals due to better performance of stomatognathic system. The higher Kapur scores in group T signifies better quality of dentures when TENS was used for definitive impression making.

Aim: The aim of this study was to compare the accuracy of full‐arch conventional implant impressions using two different materials (A‐silicone and polyether) to full‐arch digital implant impressions produced from two intraoral scanning devices. Materials and Methods: A master model was fabricated representing an edentulous mandible with four implants with internal connection placed at the sites of canines and first molars. The anterior implants were parallel to the residual ridge, while the two posterior implants had an angulation of 15° to the distal and 15° to the lingual respectively. The conventional technique was performed with open‐tray of non‐splinted impression copings. Two different impression materials were used, A‐silicone and polyether at monophase medium body consistencies. The digital impressions were obtained with the use of two different intraoral scanners, after the connection of scan bodies. A total of 10 impressions were produced for each of the four experimental groups. The conventional models as well as the master model were digitized using a high‐resolution laboratory scanner. The STL files of the models and of the intraoral impressions were imported in a powerful superimposition software, for the conduction of measurements in pairs of files. The software calculated the 3D deviations, as well as the linear and angular displacements among scan bodies at the digital files. For "trueness" measurements every STL file of each experimental group was superimposed to the digital master model, while for "precision" measurements all STL files of each experimental group were superimposed to each other. Results and Conclusions: The accuracy of full arch mandibular implant impressions was influenced both by the impression technique used (conventional vs. digital) and the impression material used (A‐silicone vs. polyether) or the intraoral scanner used (Trios vs. Heron).In terms of "trueness," A‐silicone showed the highest impression accuracy with the lowest deviation values, followed by polyether and Trios, but the differences between the three groups were in the majority not statistically significant. Heron showed statistically lower accuracy results in all measurements compared to the other groups.In terms of "precision", conventional impressions with the use of A‐Silicone or polyether were statistically significantly superior to digital impressions with either scanner. A‐Silicone and polyether showed no statistically significant difference between them. [ABSTRACT FROM AUTHOR]

Owing to the need for beauty in modern society, cosmetics are essential to enhance femininity and attractiveness. Lipstick is effective in reinforcing femininity and increasing beauty. This study conducted a psychophysical experiment to investigate the association between lipstick colors and the impressions they create. Thirty‐five observers were invited to participate in the experiment. They were asked to assess 20 lipstick colors on 23 impression scales. The results showed that the impressions created by the lipstick colors comprised three factors: charm, cuteness, and contemporary. Charm was correlated with a* and lightness value of lipstick color and the color difference between lipstick‐skin colors. Cuteness was negatively correlated with the hue angle of the lipstick colors and lightness differences between lipstick‐skin colors. Contemporary was correlated with chroma differences and negatively correlated with b* of lipstick color. These lipstick colors can be classified into three groups based on impression factors. The results showed that a* value of lipstick color and the color difference (△E) between lipstick and skin color are identified to determine the grouping of lipstick colors. [ABSTRACT FROM AUTHOR]

Preliminary impressions must record the periphery and height of maxillary defects to allow for an eventual extension of the master impression tray. These impressions are usually made with irreversible hydrocolloid. Carrying the impression material into the defect can be complex, especially in the case of a limited oral opening. Moreover, the patient can be harmed during the removal procedure, and material may be stuck in anatomical structures. The technique presented in this article avoids these issues in any maxillary defect with a two‐step preliminary impression. An elastomeric material ball is first placed in the defect until full setting. Then, this "obturator bulb" is removed and eventually relined until it is retentive. Retentions are designed on the oral side of the bulb and the bulb is placed back into the defect. Finally, an alginate over‐impression of the maxillary is made. The alginate is removed after full setting, and the obturator can be reassembled on the maxillary impression to provide a full recording of the maxillary. This protocol can safely be used for defects of any size, despite eventual limitations in oral opening. [ABSTRACT FROM AUTHOR]

Purpose: To study the influence of insertion depth and implant angulation on the 3D trueness of models obtained with different impression techniques. Materials and Methods: Four different reference models (model 1: parallel, depth of 1.5 mm; model 2: parallel, depth of 4 mm; model 3: 20-degree angle, depth of 1.5 mm; and model 4: 20-degree angle, depth of 4 mm) of partially edentulous maxillae were generated by altering implant angulations and subgingival depths. All scans of reference models were done with a laboratory scanner, and obtained data were exported into standard tessellation language format to be used as virtual reference images. Impressions were obtained from each reference model via three conventional techniques (closed tray [CT], non-hexed open tray [NHOT], and hexed open tray [HOT]) and one digital technique (intraoral scanning [IOS]). A total of 160 impressions were made. The reference and experimental scan data were superimposed by using the best-fit alignment algorithm. Angular (AD), linear (LD), and 3D (RMS) deviations were computed, and obtained data were statistically analyzed. Results: In premolar implant sites, AD and LD values were significantly affected by model type (P ≤ .001 for AD and LD) and impression technique (P = .001 for AD, P = .002 for LD). However, no significant interaction was detected (P = .703 for AD, P = .768 for LD). Model 1 (0.44 ± 0.25 for AD, 7.79 ± 6.29 for LD) and the NHOT technique (0.49 ± 0.43 for AD, 9.04 ± 8.14 for LD) exhibited the lowest mean AD and LD values. In molar implant sites, AD and LD values were significantly affected by model type (P ≤ .001 for AD and LD) and impression technique (P ≤ .001 for AD and LD), as well as by their interaction terms (P = .037 for AD, P = .005 for LD). Considering interaction terms, while the highest and lowest mean AD values were exhibited by IOS-model 4 (1.56 ± 0.25) and NHOT-model 2 (0.46 ± 0.28), respectively, the highest and lowest mean LD values were exhibited by CT-model 4 (41.40 ± 14.48) and NHOT-model 2 (8.03 ± 4.86), respectively. RMS estimate values were significantly influenced by model type (P ≤ .001) and impression technique (P ≤ .001), as well as by their interaction terms (P = .019). The highest and lowest mean RMS values were exhibited by IOS-model 4 (70.02 ± 4.74) and NHOT-model 2 (25.96 ± 17.67), respectively. Conclusion: In the case of angulated and deeply placed implants, splinted NHOT and HOT techniques can be recommended for better trueness. [ABSTRACT FROM AUTHOR]

Status-related impressions influence important interpersonal dynamics, including moral judgments of good or bad, and right or wrong, whereas these impressions can be formed based on subtle cues (e.g., formal versus casual attire of transgressors). The current research examined how attire influences moral judgments in transgressive contexts and for different transgressions. We proposed that attire would have different effects on moral judgments depending on whether transgressions were accompanied with contradictory moral claims (i.e., hypocrisy versus non-hypocrisy), and attire and hypocrisy would influence moral judgments through perceived intentionality (i.e., whether transgressions were committed intentionally or accidentally). We tested these hypotheses in four studies (total N = 1,007; including two pre-registered), by examining both people's moral blame of transgressive behaviors and their moral impressions (e.g., trustworthiness and compassion) of the transgressors. Findings were largely in line with hypotheses: People favored formal- over casual-attire targets when both transgressed in non-hypocritical contexts and with ambiguous intentionality (Studies 1 to 3). However, moral favoritism based on formal attire was diminished when transgressions were hypocritical and perceived as intentional (Studies 2 to 4). For various contexts where people (need to) make moral judgments, our findings suggest that cues of high status are key ingredients to moral evaluations, but signs of hypocrisy and intentionality may seriously undermine the workings of these cues.

People largely preserve spontaneously drawn trait inferences from others' behaviors in their memory, even when contrary information is present. However, we suggest that updating could be manifested in future predictions about others. Experiment 1 replicated previous work, showing no updating in the memory of initially inferred traits upon learning trait-inconsistent new information. Experiments 2–4 tested whether people's reliance on the initially implied traits in their future predictions changed as an indicator of updating. Participants aligned their predictions with the initially implied traits when the new information was neutral. However, after learning trait-inconsistent (vs. neutral) new information, they made weaker future predictions consistent with the initially implied traits and stronger predictions consistent with alternative (inconsistent) traits, revealing updating. The patterns were similar across continuous and categorical prediction measures (Experiment 3) and generalized to other valence-matching impressions (Experiment 4). The present work reveals nuances that extend our understanding of impression updating and suggests a utility in combining memory measures of impression formation with behavior predictions.

The correct impression in complete or partial prosthodontics is an essential stage in the manufacturing of functional dentures. Through an impression, all the necessary information is sent form the dental office to the dental laboratory, for creating the individual impression tray, with the help of which a much more accurate impression can be obtained comparing to a standard impression tray. Using the functional impression made with the help of the individual impression tray, the functional model is obtained, on which the occlusal registration rims and later on the trial denture will be made.

As a reflection of social patterns, culture is bound to change and the representations from the past distorted in the present need to be decoded to remove the staleness and fixation on various notions passed as absolute truths. This dichotomy inspires an investigation into an iconic representation of womanhood from the stature of an episode from mythological epic Mahabharata and the paintings of Shakuntala by the painter Prince Ravi Varma of erstwhile Travancore in the state of Kerala in colonial India to unravel the stories that characterized popular imagination of women in history. The theoretical framework of aesthetics in the depiction of human forms that define perceptions of gender directs this study to avail a close reading to evaluate the growth of empowerment of women within the dialectics of history and culture. 'Ekphrasis' studies mainly how visual arts are represented in literature and here interestingly visual art becomes the ekphrasis of the written text. A proposal of the theory of 'elimination', the study intends to debunk the societal gaze of the feminine form as fragile hindering the strength of character by analyzing the hidden details in art. The relevance becomes manifold in the twenty-first century as the new generation is ardently trying to break stereotypes. The limitations of binary ideas of masculine and feminine are interwoven mainly with physical characteristics. The pressure to mimic these attributes leads to the exclusion of anything beyond that idea which disturbs the balance of gender equality and justice. [ABSTRACT FROM AUTHOR]

To clarify comfortable bedding colors, we examined 80 psychiatric inpatients' impressions of bedding in 6 different tones (pale, dull, bright, greyish, deep, and light) of blue, focusing on the suitability for patient rooms. 1) In both the male and female groups, the samples chosen as the most and least suitable for patient rooms were pale tone and greyish tone, respectively. 2) The female group rated pale tone and light tone more positively than the male group. 3) Through factor analysis, 2 factors were identified: [psychological comfort] and [brightness/warmth]. For Factor 1, greyish tone was rated significantly lower than pale and light tones only in the female group. For Factor 2, greyish tone was rated significantly lower than pale and light tones in both the male and female groups. Based on these findings, bedding in various tones of blue, except for greyish tone, is recommendable for psychiatric wards. [ABSTRACT FROM AUTHOR]

Our research aims to investigate the impact mechanism of brand loyalty among gamers during the gaming process within the framework of brand loyalty theory and cognitive theory. We surveyed game players from Zhejiang Province, China. The research methods include a questionnaire survey and structural equation modelling. Results show that game experience, interaction, and impression are positively correlated with game trust, while game trust is positively correlated with game brand loyalty. Game trust, as a mediator variable, plays a complete mediation role. The clustering results of player gender and age as moderating effects are not significant. Based on the analysis results, we have suggested corresponding policy recommendations and reflections. Our research contributes to the analysation of impact mechanism of brand loyalty during the gaming process through the establishment of a structural equation model and provides suggestions and reflections on the development of the gaming industry.

Purpose: The purpose of the article is to present the author’s own comprehensive method of testing impression management in narrative reporting and the possibility of using it to evaluate and measure impression management and identify the strategy of impression management in letters to shareholders. Methodology/approach: The development of the method of testing impression management in narrative reporting was preceded by a critical analysis of the literature. Content analysis and the IMNR (impression management in narrative reporting) index were used in the empirical study. The study covered ten letters to shareholders of Polish companies. Findings: The article presents a tool for assessing and measuring impression management, showing how it is calculated. It also presents the results of a survey, showing the possibilities of using the IMNR index. In the audited board of directors’ letters, the occurrence of all analysed impression management strategies was identified. The article discusses selected methods of impression management observed in those documents. Research limitations/implications: The proposed IMNR index is limited to selected impression management strategies and the means by which they can be detected. As the study was limited to selected companies, future research may investigate other entities or reporting forms. Additionally, only documents written in Polish were analysed. Originality/value: The article presents the original IMNR index, which makes it possible to comprehensively examine impression management and compare reports. The conducted empirical study covered a wide range of ways of managing impressions. Documents written in Polish were examined. As Polish researchers have been dealing with the issue of impression management by Polish companies since only relatively recently, the research gap, which this article partially fills, is extremely wide.

Abstract Purpose This systematic review aimed to investigate the accuracy of intraoral scan (IOS) impressions of implant-supported restorations in in vivo studies. Methods A systematic electronic search and review of studies on the accuracy of IOS implant impressions were conducted to analyze the peer-reviewed literature published between 1989 and August 2023. The bias analysis was performed by two reviewers. Data on the study characteristics, accuracy outcomes, and related variables were extracted. A meta-analysis of randomized control trials was performed to investigate the impact of IOS on peri-implant crestal bone loss and the time involved in the impression procedure. Results Ten in vivo studies were included in this systematic review for final analysis. Six studies investigated the trueness of IOS impressions, but did not reach the same conclusions. One study assessed the precision of IOS impressions for a single implant. Four clinical studies examined the accuracy of IOS implant impressions with a follow-up of 1–2 years. In full arches, IOS impression procedure needed significantly less time than conventional one (mean difference for procedure time was 8.59 min [6.78, 10.40 min], P

The review of the works and the writings of philosophers regarding the origin of philosophical concepts and the origin of the concepts and imaginations before it are indicative of the gradual and influenced formation and importance of this issue from a series of ideas in both the west and Islam. In the western world, the idea of innate ideas raised by rationalists and the rejection of the same idea by empiricists finally leads the Scottish philosopher Hume, who is evasive from the mysterious philosophy,to tract the origin of concepts and adaptations and by presenting a plan to refer concepts and adaptations has beaten all philosophies and introduced them as illusory and invalid concepts,and appeals to justifying the existence of these concepts in the mind to psychological and imaginary bases. later and in the passing of time due to the entry of western ideas into Iran,especially in the contemporary era,the issue of the origin of concepts and ideas (in general) and the origin of philosophical(in particular) by Allamh Tabatabayi has doubled its value and importance. Allameh, like Hume while rejecting the idea of innate and preconceived notions of the mind and bringing science to the field of presence and emphasizing the inherent existence and discovery of science and by reference all concepts and ideas to present science the validity and epistemological value of the philosophical concepts which are in Hume's philosophical dictionary restores what was disappeared and gives new life to philosophy and its concepts.

Objective: This study investigated how the number of images collected for digital measurements in dentistry affects accuracy compared with traditional methods. Methods: A Frasaco maxillary model was scanned using a SHINING 3D AutoScan-DS-MIX dental 3D scanner to create an STL file. The maxilla was molded 10 times using polyvinyl siloxane (Zhermack Elite HD+) to produce plaster models, which were scanned with the same reference scanner to generate 10 STL files. The Frasaco model was scanned 10 times, capturing images in intervals of 800–1000, 1000–1200, and 1200–1500 using a 3Shape TRIOS 3 intraoral scanner, creating additional STL files. These were analyzed with reverse engineering software. Results: The most accurate measurements were obtained using 1200–1500 images. Conventional impression techniques performed significantly worse. There was a significant difference between the groups Digital 1200–1500 and Plaster (p < 0.001) and between Digital 800–1000 and Plaster (p = 0.007). No significant difference was found when the digital groups were compared among themselves. There was also no significant difference between the Plaster and Digital 1000–1200 groups. To compare precision values that were normally distributed across three or more methods, a one-way ANOVA was used. Trueness values that were not normally distributed with three or more methods were compared employing the Kruskal–Wallis test. Conclusions: Different image counts affect digital measurement accuracy. The most accurate measurements were obtained when collecting 1200–1500 images. Conventional impression techniques were shown to perform significantly worse than digital impression.

A coach's nonverbal communication (NC) plays a central role in the construction of the coach–athlete relationship. Moreover, perceived NC and its effect on communication ability and coaching evaluation may differ according to the athletes' demographics. This study explored the impact of perceived NC on coaching evaluation and overall communication among different genders and age groups. The study recruited 233 athletes from five high schools and seven university teams in Japan. The coaches' NC, communication ability, and coaching evaluations were assessed. Negative and positive NC directly influenced coaching evaluation in female athletes. Specifically, negative NC directly impacted coaching evaluation in high school athletes, whereas positive NC directly influenced coaching evaluation in university athletes. Positive NC consistently influenced communication ability regardless of demographics. The findings promote talent development and team management in the coaching context. [ABSTRACT FROM AUTHOR]

People often form immediate expectations about other people, or groups of people, based on visual appearance and characteristics of their voice and speech. These stereotypes, often inaccurate or overgeneralized, may translate to robots that carry human-like qualities. This study aims to explore if nationality-based preconceptions regarding appearance and accents can be found in people's perception of a virtual and a physical social robot. In an online survey with 80 subjects evaluating different first-language-influenced accents of English and nationality-influenced human-like faces for a virtual robot, we find that accents, in particular, lead to preconceptions on perceived competence and likeability that correspond to previous findings in social science research. In a physical interaction study with 74 participants, we then studied if the perception of competence and likeability is similar after interacting with a robot portraying one of four different nationality representations from the online survey. We find that preconceptions on national stereotypes that appeared in the online survey vanish or are overshadowed by factors related to general interaction quality. We do, however, find some effects of the robot's stereotypical alignment with the subject group, with Swedish subjects (the majority group in this study) rating the Swedish-accented robot as less competent than the international group, but, on the other hand, recalling more facts from the Swedish robot's presentation than the international group does. In an extension in which the physical robot was replaced by a virtual robot interacting in the same scenario online, we further found the same results that preconceptions are of less importance after actual interactions, hence demonstrating that the differences in the ratings of the robot between the online survey and the interaction is not due to the interaction medium. We hence conclude that attitudes towards stereotypical national representations in HRI have a weak effect, at least for the user group included in this study (primarily educated young students in an international setting).

In full arches, IOS impression procedure needed significantly less time than conventional one (mean difference for procedure time was 8.59 min [6.78, 10.40 min], P < 0.001), prosthetic survival rate was 100%, and marginal bone levels of all participants could be stably maintained (mean difference in marginal bone loss at 12 months was 0.03 mm [-0.08, 0.14 mm], P = 0.55). Conclusions: The accuracy of IOS impressions of implant-supported restorations varied greatly depending on the scanning strategy. The trueness and precision of IOS in the partial and complete arches remain unclear and require further assessment. Based on follow-up clinical studies, IOS impressions were accurate in clinical practice. However, these results should be interpreted with caution, as some evidences are obtained from the same research group. [ABSTRACT FROM AUTHOR]

Featured Application: An alginate-based impression material with bacteriostatic properties for application in the production of dental prosthetics, requiring a less labour-intensive process of disinfection. Disinfection of alginate impressions used in dental prosthetics is a very problematic procedure, during which the dimensions of the obtained model can change, and it can be easily mechanically damaged. Therefore, it would be beneficial to create a material with bacteriostatic properties for this application. In this work, we investigated alginate materials with the addition of 0.25–1.0 wt% of zirconium phosphate-based ion exchange resin containing silver and compared them with commercial alginate impression products. The obtained materials passed the normative requirements of ISO 21563:2021 (setting time, elastic recovery, strain in compression, compatibility with gypsum, detail reproduction, tearing strength, and linear dimensional change) as well as bacteriostatic properties in relation to Streptococcus mutans. The newly developed alginate materials met all the properties required by the standards. Their setting time was comparable to the commercial materials, and their 24 h contraction did not exceed 1.3%. Furthermore, the tearing strength was 0.42–0.48 MPa, less than that of the comparative commercial materials (0.52–0.56 MPa). From the point of view of clinical practice, it will be possible to create an alginate material with bacteriostatic properties that will prevent the transmission of cross-infections.

The materials utilized in various domains of prosthodontics have changed overtime. In recent years, patients have been requesting a metal-free, lightweight, and tooth-colored prosthesis. In dentistry, metal and other ceramics are used in a variety of treatment methods. Polyetheretherketone (PEEK) can be employed in a variety of ways in prosthodontics. PEEK is being investigated as an alternative to metal and glass ceramics due to their acceptable fracture resistance, shock-absorbing capabilities, and improved stress distribution. Due to its favorable mechanical and chemical properties, PEEK is recognized as a high-performance polymer in engineering and medical applications. In dentistry, a material must have excellent biocompatibility, strong mechanical qualities, be resistant to high temperatures, have a low moisture absorption and elasticity modulus, be flexible, and have a high chemical wear resistance. PEEK material possesses all of these characteristics, making it ideal for use in dentistry. Using PEEK with computer-aided design and computer-aided manufacturing fabrication (CAD/CAM) will allow us to save natural teeth in tough situations. The technique allows the patient to have upgrades that are physiologically and technically superior in processing and improve their appearance. Dental rehabilitation with complete satisfaction is in doubt, mostly because of the imperfect adaptation of the crown. Hence, the restoration of teeth using PEEK with CAD/CAM technology as an alternative to glass or metal ceramics provides an excellent opportunity for better esthetic restoration and patient satisfaction. In this present case presentation, we highlighted two clinical cases showing teeth in the upper left arch and two teeth in the lower right region of the jaw using CAD/CAM-fabricated PEEK post, core, and PEEK crown, which were briefly demonstrated.

Purpose: To compare the marginal accuracy of zirconia crowns fabricated by different workflows (conventional and digital) and designs (monolithic and veneered). Materials and Methods: A prepared maxillary first molar was used for the study. Four workflow combinations were evaluated: (1) intraoral scanning and monolithic zirconia (IOS‐M), (2) intraoral scanning and veneered zirconia (IOS‐V), (3) conventional impression and monolithic zirconia (IMP‐M), and (4) conventional impression and veneered zirconia (IMP‐V). All of the specimens had similar designs. The veneered groups had a buccal cutback for esthetic veneer application. A total of 10 crowns were produced in each workflow. The vertical and horizontal marginal accuracies were measured with a traveling microscope. Depending on the normality of the data, one‐way analysis of variance test or Kruskal‐Wallis test were applied to evaluate the differences among the groups (α = 0.05). Results: The most superior vertical marginal accuracy was observed for IOS‐V (mean = 22.5 μm; SD = 6.7 μm), followed by IMP‐V (mean = 23.9 μm; SD = 7.8 μm), IOS‐M (mean = 28.7 μm; SD = 10.3 μm), and IMP‐M (mean = 39.8 μm; SD = 22.0 μm), respectively (p < 0.001). The IOS‐M had the greatest mean horizontal discrepancies (mean = 23.9 μm; SD = 4.3 μm) followed by IMP‐M (mean = 21.3 μm; SD = 5.7 μm), IMP‐V (mean = 19.2 μm; SD = 5.3 μm) and IOS‐V (mean = 17.6 μm; SD = 5.7 μm) (p < 0.001). Conclusions: Monolithic zirconia crowns fabricated digitally had superior marginal accuracy than monolithic zirconia crowns fabricated conventionally. Esthetic buccal veneering of predominantly monolithic zirconia copings improved the vertical and horizontal marginal accuracies. [ABSTRACT FROM AUTHOR]

In today's environment, where consumers have a wide range of information available to them, it is important for companies to use more effective and flexible approaches to the market. Modern information technology helps the marketer to be closer to the buyer than in the past and to understand the customer's needs and desires well. In addition, marketers need to have a good understanding of the capabilities and benefits of different marketing communication tools and media channels. In today's competitive environment, it is becoming increasingly important for companies to use incentives that are better suited to today's targeted strategies. Effective marketing communications play an important role in a company's success in the marketplace. It is important in creating an impression of the company and its brands. Events help companies to achieve this goal. The purpose of this paper is to summarise and present the main benefits that companies can achieve through the intelligent use of events. Events are used by many companies to impress other people. And companies can gain their favour by making a great impression on the public. Thus, event marketing influences consumer attitudes towards different brands, consumer behaviour and stimulates purchases. An important question is when and how special events will be implemented. Their proper planning, organisation and execution will bring the company high recognition and economic benefits. Methodology. Secondary data was used in the course of writing this article. Modern scientific works of scientists and researchers were studied, and information was searched for using Internet sources. The paper examines modern forms of event marketing, individual approaches to work in this area and aspects of its development. Research results. Based on various reliable sources of information, a clear picture of the current situation in Georgia in this area was created. It has been found that companies do not use measures with the frequency that would bring them high results. They use only certain approaches. The paper examines the conceptual aspects of event marketing, analyses the definitions and opinions of various scientists and specialists in this area. Practical implications. The article discusses the risks and problems associated with the implementation of events, and presents a number of conclusions and recommendations to improve the efficiency of the use of events.

People often form immediate expectations about other people, or groups of people, based on visual appearance and characteristics of their voice and speech. These stereotypes, often inaccurate or overgeneralized, may translate to robots that carry human-like qualities. This study aims to explore if nationality-based preconceptions regarding appearance and accents can be found in people’s perception of a virtual and a physical social robot. In an online survey with 80 subjects evaluating different first-language-influenced accents of English and nationality-influenced human-like faces for a virtual robot, we find that accents, in particular, lead to preconceptions on perceived competence and likeability that correspond to previous findings in social science research. In a physical interaction study with 74 participants, we then studied if the perception of competence and likeability is similar after interacting with a robot portraying one of four different nationality representations from the online survey. We find that preconceptions on national stereotypes that appeared in the online survey vanish or are overshadowed by factors related to general interaction quality. We do, however, find some effects of the robot’s stereotypical alignment with the subject group, with Swedish subjects (the majority group in this study) rating the Swedish-accented robot as less competent than the international group, but, on the other hand, recalling more facts from the Swedish robot’s presentation than the international group does. In an extension in which the physical robot was replaced by a virtual robot interacting in the same scenario online, we further found the same results that preconceptions are of less importance after actual interactions, hence demonstrating that the differences in the ratings of the robot between the online survey and the interaction is not due to the interaction medium. We hence conclude that attitudes towards stereotypical national representations in HRI have a weak effect, at least for the user group included in this study (primarily educated young students in an international setting).

Humans exhibit colour vision variations due to genetic polymorphisms, with trichromacy being the most common, while some people are classified as dichromats. Whether genetic differences in colour vision affect the way of viewing complex images remains unknown. Here, we investigated how people with different colour vision focused their gaze on aesthetic paintings by eye-tracking while freely viewing digital rendering of paintings and assessed individual impressions through a decomposition analysis of adjective ratings for the images. Gaze-concentrated areas among trichromats were more highly correlated than those among dichromats. However, compared with the brief dichromatic experience with the simulated images, there was little effect of innate colour vision differences on impressions. These results indicate that chromatic information is instructive as a cue for guiding attention, whereas the impression of each person is generated according to their own sensory experience and normalized through one's own colour space.

Objective: Our study aimed to observe the effects of different gingival masks and production techniques on model accuracy. Methods: Impressions were taken from an upper jaw model with 6 parallel implants using the open tray technique. Then, 20 models were produced using 3 different gum masks; each group was divided into those produced as single- and double-piece forms. The produced models were scanned using a laboratory scanner. Scanned data were observed for the angular changes of each analog, and the average angular deviation values were calculated for each model. All 6 groups were compared with each other. Kruskal--Wallis test was used in order to evaluate the level of significance. Results: It was observed that the samples made of a harder type of additional silicone showed more angular deviation compared to the samples made of a softer type of additional silicone and condensation silicone. The production technique, whether single or double piece, did not show any effect on model accuracy. Conclusion: Based on this study, it was observed that harder types of silicone gingival masks had the advantage of being easy to use and manipulate but showed more angular deviation than other groups included in the study.

Introduction: Epidermolysis bullosa (EB) is a group of genetic disorders characterized by fragility of the skin and mucosal membranes. Dystrophic EB (DEB) is caused by mutations in the gene coding for type VII collagen. Among the most frequent oral manifestations in Recessive DEB (RDEB) are oral ulcers and blisters, absence of tongue papillae and palatal rugae, ankyloglossia, oral vestibule obliteration, and microstomia. The following report describes a modified impression technique used in a patient with severe RDEB and severe microstomia to obtain models for orthodontic treatment with aligners. Case Report: A 25‐year‐old female patient with severe RDEB was referred for orthodontic treatment. Severe microstomia (8 mm), hindered the use of conventional trays or intraoral scanners to design the aligners. Therefore, a contracture release surgery in combination with a modified impression technique was performed to obtain an optimal impression and subsequent aligners for orthodontic treatment. Discussion: This case presents an alternative strategy to provide orthodontic treatment with aligners in patients with severe microstomia due to severe RDEB. Reports of orthodontic treatment in people living with EB, especially in RDEB, are still rare, with few publications about fixed braces, early teeth extraction and removable devices, and none using aligners. Most of the impression techniques reported are aimed at oral rehabilitation. The multidisciplinary approach and impression technique reported should broaden the alternatives of orthodontic techniques provided to patients with EB and severe microstomia. Conclusions: This article describes an oral contracture release surgery and modified impression technique for obtaining good quality impression for the design of orthodontic aligners in patients with severe microstomia due to severe RDEB.

The assessment of rehabilitation outcomes requires a patient documentation protocol, including records obtained at standardized ages, to compare different types of surgeries, their effects, as well as between different rehabilitation centers. The aim of this paper was to present proper trays for babies with different types of cleft lip and palate, which are used in the outpatient routine at Hospital of Rehabilitation of Craniofacial Anomalies/USP (HRAC/USP). The customized trays are made with self-curing acrylic resin. The tray must have suitable depth to copy the buccal sulcus, and wax is usually applied to contour the tray edge, and the adjustment of the tray to the fornix, making the tray specific for each child. The impression precludes the utilization of dental casts for diagnosis, treatment plan, and research measurements. In the clinical practice at HRAC-USP, it was observed that customized trays increased the quality of impression, accurately reproducing anatomical features of dental arches of babies with oral clefts.

Introduction: An implant-supported prosthesis requires a precise imprint to provide a good fit. It has been suggested that for implant/abutment level impressions, both the indirect (closed tray) and direct (open tray) methods are effective in achieving a passively fitting prosthesis. Aim: With an open plate embed level impression technique, this in vitro investigation set out to evaluate three different elastomeric imprint materials for their relative rigidity and precision. Materials and Methods: Sixty bespoke trays were created. Part I (rotational opposition assessment) of the investigation included selecting 30 uniquely shaped plates at random and using them to create embed-level open plate engraves. The second part of this investigation (evaluation of rotational discrepancy and vertical inconsistency) used open plate embed level impressions generated with the remaining thirty individualized plates to evaluate how well these materials recreated the patient's impressions. Result: Within the bounds of the current investigation, vinylpolysiloxane had the highest degree of stiffness among the impression materials examined in comparison to polyether and vinylsiloxanether, as seen by its much greater rotational resistance to torquing. A rotational discrepancy was shown to be much lower in polyether open tray implant level impressions compared to vinylpolysiloxane and comparable to vinylsiloxane. Conclusion: In this investigation, the firmest impression medium was vinylpolysiloxane, followed by polyether and vinylsiloxanether for taking imprints of implants. Polyether material, however, was more precise than vinylpolysiloxane and vinylsiloxanether. [ABSTRACT FROM AUTHOR]

This study aims to investigate the effect of impression management on employee contextual performance in service organizations using quantitative methods. The social influence theory, which explains the role of superior influence over the subordinate, served as the theoretical underpinning for the study. A cross-sectional survey design was adopted in line with positivism research philosophy. The accessible population of this study consists of one hundred selected service-oriented firms (four-star hotels, fast food restaurants, and travel agencies) operating in the southern part of Nigeria. The sample consists of middle managers, human resource managers, front desk officers, housekeepers, and customer relationship managers. Frequency distribution was used to analyze participants’ profiles, while linear regression was employed to analyze the formulated hypotheses. Statistical Package for the Social Sciences (SPSS) 20.0 served as statistical software. Linear regression results suggest that self-promotion exerted a significant positive effect on co-worker support. Ingratiation demonstrated a significant positive effect on customer satisfaction. It appears that exemplification exerted a significant positive effect on enterprise compliance. The outcome of this study has demonstrated that traditional managerial skills can no longer hold water in contemporary service-oriented organizations because of the workplace's dynamic and changing technological structure. This study concludes that impression management can assist managers in influencing their employees positively to achieve organizational objectives. Doi: 10.28991/ESJ-2023-07-02-05 Full Text: PDF

The article is devoted to the problems of representation of urban myth-making in social networks. The purpose of the study is to identify the specifics of the representation of urban myth-making in social networks on the example of myth-making activity in the cities of the Volga region. As part of the research, materials published in groups of the VKontakte social network over the past 10 years were studied. In the article, urban myth-making is understood as the process of creating legends reflecting the historical and cultural peculiarity of a particular city. As a result of this research, common characteristic features and distinctive qualities of the myth-making of the cities of the Volga region were identified, directly related to their history, the contingent of the population and the type of its activity. When analyzing the material of the social network, it was revealed that the development of urban myth-making bears the imprint of the peculiarities of the perception of historical events, urban objects, and specific personalities by the population, which are reflected in the images of local legends created. The article is addressed to researchers of the humanitarian field of myth-making activity, as well as to a wide audience of readers interested in this topic.

The design of the light environment plays a critical role in the interaction between people and visual objects in space. Adjusting the space's light environment to regulate emotional experience is more practical for the observers under lighting conditions. Although lighting plays a vital role in spatial design, the effects of colored lights on individuals' emotional experiences are still unclear. This study combined physiological signal (galvanic skin response (GSR) and electrocardiography (ECG)) measurements and subjective assessments to detect the changes in the mood states of observers under four sets of lighting conditions (green, blue, red, and yellow). At the same time, two sets of abstract and realistic images were designed to discuss the relationship between light and visual objects and their influence on individuals' impressions. The results showed that different light colors significantly affected mood, with red light having the most substantial emotional arousal, then blue and green. In addition, GSR and ECG measurements were significantly correlated with impressions evaluation results of interest, comprehension, imagination, and feelings in subjective evaluation. Therefore, this study explores the feasibility of combining the measurement of GSR and ECG signals with subjective evaluations as an experimental method of light, mood, and impressions, which provided empirical evidence for regulating individuals' emotional experiences.

This study aims to provide listening training and comprehension support using a communication robot for young and overseas staffs who have problems understanding dialects in medical and nursing care settings. In this study, we conducted an impression survey of university students in a region where dialects are used using a robot and a person who speaks standard Japanese and a dialect (Mikawa dialect). Moreover, a nationwide impression survey using only a robot was also performed. In the dialect-using region, the robot speaking the dialect gave the impression of being cute but difficult to understand, whereas no difference in impression was observed in the nationwide survey. However, the analysis of the free text showed that the dialect and motion of the robot gave a positive impression. Based on the factors contributing to the positive impression of the dialect, we aim to construct a training program that motivates young and foreign personnel. [ABSTRACT FROM AUTHOR]

This study aimed to examine the effect of inter-dental abutment distance on the accuracy of digital and conventional impression methods. Five maxillary and mandibular models were prepared with different inter-dental abutment distances. Digital scans were obtained using an extraoral laboratory scanner as reference data. Each group was scanned 8 times using the intra-oral scanner for the digital method. For the conventional impression method, 8 additional silicone impression material was used to generate the stone casts from each group. Then casts were scanned. In the next step, stereolithography (STL) data was exported from the scans. The STL files were super-imposed on the reference scans using 3shape dental designer software to make the measurement. Kolmogorov-Smirnoff was used to determine if the data were normally distributed. In the digital impression method, as the abutment distance increased, the accuracy decreased. Various inter-dental abutment distances in digital groups showed significant differences (p=0.016) in impression accuracy, while the difference among conventional groups was not statistically significant (p=0.822). In the digital method, the mean inter-dental abutment between the 4-5 and 3-7 groups, 4-6 and 3-7 groups had a significant difference (p<0.05). However, the conventional method revealed no significant differences (p>0.05) between groups. In conclusion, when the inter-dental abutment distance exists and is surrounded by soft tissue, the possibility of error in the digital impression method is higher than in the conventional impression method.

The study investigated children's attitudes toward and impressions of a narrated stop-motion animation called "slowmation" and the relationship between the variables when learning with slowmation. An analogue scale and an ordinal scale were used respectively to collect children's learning attitude and learning impression data. A total of 30 preschool children aged 5–6 participated in this slowmation activity. The results revealed that most of the children had positive attitudes when learning with the activity. Nevertheless, some boys indicated that they experienced no delight at all. Regarding the children's impressions, the results showed that most of them highly agreed with the joyfulness and enjoyment that slowmation brought to their learning. There was a positive relationship between their delight level and their learning joyfulness and enjoyment. The findings suggest that slowmation could be utilized in a creative learning process and could also be used as an interesting learning medium. If the teacher plans the learning materials properly, children could benefit from the moving image education by slowmation. [ABSTRACT FROM AUTHOR]

Background: Recording accurate impressions from maxillary defects is a critical and challenging stage in the prosthetic rehabilitation of patients following maxillectomy surgery. The aim of this study was to develop and optimize conventional and 3D-printed laboratory models of maxillary defects and to compare conventional and digital impression techniques using these models. Methods: Six different types of maxillary defect models were fabricated. A central palatal defect model was used to compare conventional silicon impressions with digital intra-oral scanning in terms of dimensional accuracy and total time taken to record the defect and produce a laboratory analogue. Results: Digital workflow produced different results than the conventional technique in terms of defect size measurements which were statistically significant (p < 0.05). The time taken to record the arch and the defect using an intra-oral scanner was significantly less compared with the traditional impression method. However, there was no statistically significant difference between the two techniques in terms of the total time taken to fabricate a maxillary central defect model (p > 0.05). Conclusions: The laboratory models of different maxillary defects developed in this study have the potential to be used to compare conventional and digital workflow in prosthetic treatment procedures.

This study examined the suitability and impressions of various bedding colors among 66 nurses and 64 patients on psychiatric wards. (1) The colors chosen as suitable for hospital rooms were white in the male nurse and male patient groups, pale green in the female nurse group, and pale red in the female patient group. As unsuitable bedding colors, pale yellow was chosen by the male and female nurse groups and the female patient group, and pale red by the male patient group. (2) There were marked differences in the impressions of white and pale blue between the nurse and patient groups. (3) Factor analysis identified 2 factors: [psychological comfort] and [brightness/warmth]. The mean factor scores were relatively high for white, pale green, and pale blue for [psychological comfort］，and were pale red and pale yellow for [brightness/warmth]. Thus, selecting bedding in consideration of patient perspectives is necessary [ABSTRACT FROM AUTHOR]

Introduction: This systematic study compared the accuracy of digital and conventional impressions in completely and partially edentulous cases. Materials and methods: Exploration was performed in MEDLINE, EMBASE, Scopus and Google scholar databases. The focused subject of exploration in our systematic strategy was in a PICO set up. Results and discussion: Following screening of the explored studies, 11 were found eligible. Five in vitro studies were conducted on completely edentulous subjects, while 5 in vitro and 1 clinical article evaluated the partially edentulous ones. A quantitative analysis was conducted for five studies in partially edentulous subjects, with high rates of heterogeneity. We carried out a random-effects model to determine the effect size. According to the five reports on partially edentulous patients, the mean 3D difference among conventional and digital methods was 14.13 µm (95% CI: 9.83, 18.43), while the digital method gave a nominal difference (P=0.00). Six studies were not involved in meta-analysis because of the heterogeneity between plans. Angulation influenced accuracy in the partially edentulous impressions (P=0.47). Conclusions: Based on in vitro examinations, digital scans appear to be the same as conventional implant impressions in terms of 3D accuracy. However, clinical studies are suggested to examine the clinical accuracy of digital scans. [ABSTRACT FROM AUTHOR]

Azim Murtaza, in his most isolated place, has gently cut the curve of his possibilities along with his age. The imitation of the poets begins to show its colors. In the art of Azim Murtaza, the whole evolution is slowly unfolding and one can feel that he hates the terms of wearing a belt and a clock. He is not just a good lion. He say good ghazals, his poems are not prisoners of his loneliness, his poems are prisoners of the group of his companions, and they fly in the direction of the thoughts. The greatest sorrow of Azim Murtaza, the seeker of the original grief, is that the manifestations of grief are not ready to leave him. It should be that this failed attempt of Azim Murtaza is the most powerful part of his personality and this is the point where he seems to repeat the steps taken by modern poets.
