Anterior immediate implant placement (IIP) has many biological and esthetic challenges, including inevitable soft and hard tissue loss after extraction. Previous literatures have discussed the facial bone architecture and defective socket classification. However, none of them discussed the depression of the cervical root area which can be seen frequently after IIP in type IIB and U-shaped defective sockets. In our limited experiences, we found that the labial interproximal bone edges of type IIB and U-shaped defect dominated the esthetic result after IIP. With more labial projection of the interproximal bone present, better esthetic result could be expected in the facial aspect. With adequate evaluation of this osseous scalloping before IIP, both patient and clinician could have a comprehensive understanding of the final esthetic result. This article also detailed the process of patient selection, diagnosis, surgical options, and executions required to achieve functional and esthetic success with IIP and provisionalization.

Objective: To compare the patients' satisfaction between patients treated with single tooth implant (STI) or resin bonded bridge (RBB) for single missing tooth replacement. Methods: A cross-sectional study was conducted in Faculty of Dentistry, Universiti Teknologi MARA (UiTM). Patients treated using STI (n=26) and RBB (n=26) were prospectively recruited. A validated patient satisfaction questionnaire was given to the participants to assess the aesthetics, masticatory function, phonetics, ease of cleaning and cost satisfaction using 7-point Likert scale. Demographic data (gender and age) and treatment data (site of treatment) were also collected. Differences in various aspects of satisfaction were compared. Results: STI and RBB groups has similar demographic and treatment characteristics. Both groups revealed high satisfaction with most of the aspects in the questionnaire. There was no statistically significant difference in overall satisfaction between the two treatment groups (p = 0.189). However, STI group had a significant higher score in existing appearance (p = 0.010), mastication (p = 0.018) and phonetics (p = 0.029) compared with RBB. Level of satisfaction did not differ by gender, age and site of the prostheses (p > 0.05). Almost all of the participants would choose to undergo the same treatment again in UiTM (STI = 96.2%, RBB = 92.3%). Conclusion: Both STI and RBB participants were highly satisfied with the aesthetics, phonetics, cost and found that the treatment fees were justified and reasonable in UiTM. Therefore, both treatment options are good to be indicated for single missing tooth replacement. [ABSTRACT FROM AUTHOR]

The objective of this study was to evaluate the factors influencing the willingness to pay for a single tooth implant in Malaysia and to assess if an additional evidence-based patient education video increases the willingness to pay. A total of 100 subjects seeking single tooth replacement at the Oral Health Centre, International Medical University (IMU), Kuala Lumpur, Malaysia, were asked to complete questionnaires about personal demographics and personality traits. Subsequently, they were randomly allocated into two groups. Group C received a conventional patient–dentist interaction on treatment options for missing teeth, while Group EV received the same content with an additional evidence-based video on the survival rate and complications for each option from recent meta-analyses. Willingness to pay the median price and the highest price that the subjects were willing to pay were assessed by a structured bidding process. A higher annual income was significantly associated with willingness to pay the median price for a single tooth implant (χ2 = 6.91, p = 0.03). Dominant personality traits of openness (r = −0.25), conscientiousness (r = −0.30) and agreeableness (r = −0.20) were negatively correlated with the highest price that the patients were willing to pay for a single tooth implant (Pearson’s correlation test, p < 0.05). No significant difference in willingness to pay was found between Group C and Group EV (χ2 = 0.05, p > 0.05). In conclusion, patient education strategies for single tooth replacements with dental implants should be customized based on a patient’s personality and income to maximize effectiveness.

In the anterior region, the common reason for tooth loss is due to traumatic injury or congenital anomaly. Loss of a single tooth may cause functional and esthetic deficits to the patient. There are different treatment options available for replacing a missing incisor. Implant dentistry should be considered as first treatment alternative for replace a missing tooth. This case report presents the replacement of a missing maxillary left central incisor in a compromised site with dental implants along with bone graft followed by frenectomy to obtain a good clinical result and for better function and esthetics of the patient.

A new prosthetic concept, today available under the name CeraOne♠, for single tooth replacement with the Brånemark system is described. This concept is characterized by a new design of the prefabricated components. A mechanical torque driver is used together with a gold screw and a special counter-torque device to ensure that the screw is tightened in an optimal manner to resist screw loosening and only transmit minor stress to the fixture interface. Another characteristic is the use of a prefabricated cap of sintered aluminum oxide as the basis for the ceramic crown. The crown is cemented to provide better esthetic possibilities even in situations of somewhat unfavorable fixture placement. [ABSTRACT FROM AUTHOR]

Background It is unclear if an intact buccal bony plate is a prerequisite for immediate implant placement in post-extraction sockets. The aim of this 5-year randomized controlled trial was therefore comparison of peri-implant soft and hard tissue parameters, esthetic ratings, and patient-reported satisfaction of immediate implant placement in post-extraction sockets with buccal bony defects of >= 5 mm in the esthetic zone, with delayed implant placement after ridge preservation.Methods Patients presenting a failing tooth in the esthetic region and a buccal bony defect of >= 5 mm after extraction were randomly assigned to immediate (Immediate group, n = 20) or delayed (Delayed group, n = 20) implant placement. Second-stage surgery and placement of a provisional restoration occurred 3 months after implant placement in both groups, followed by definitive restorations 3 months thereafter. The follow-up was 5 years. Marginal bone level (primary outcome), buccal bone thickness, soft tissue parameters, esthetics, and patient-reported satisfaction were recorded.Results Mean marginal bone level change was -0.71 +/- 0.35 mm and -0.54 +/- 0.41 mm in respectively the Immediate group and the Delayed group after 5 years (P = 0.202). This difference, and in other variables, was not significant.Conclusions Marginal bone level changes, buccal bone thickness, clinical outcomes, esthetics, and patients' satisfaction following immediate implant placement, in combination with bone augmentation in post-extraction sockets with buccal bony defects of >= 5 mm, were comparable to those following delayed implant placement after ridge preservation in the esthetic zone.

Background The use of intraoral scanners (IOS) has facilitated the use of digital workflows for the fabrication of implant-supported prostheses not only for single missing teeth, but also for multiple missing teeth. However, the clinical application of IOS and computer-aided design/manufacturing (CAD/CAM) in implant-supported prosthodontics remains unclear. This study aimed to compare the accuracy of digital and silicone impressions for single-tooth implants for bounded edentulous spaces and two-unit and three-unit implant-supported fixed dental prostheses for free-end edentulous spaces. Methods This study enrolled 30 patients (n = 10 for each of the three groups) with an average age of 61.9 years. Conventional silicone-based and digital IOS-based impressions were made for all patients, and the implant superstructures were fabricated. We measured the scan-body misfit and compared the accuracy of the impressions for single-unit, two-unit, and three-unit implant prostheses with a bounded edentulous space by superimposing the standard triangulated language (STL) data obtained from IOS over the STL data of the plaster model used for final prosthesis fabrication. The scan bodies of the superimposed single-molar implant, two-unit implant prosthesis without teeth on the mesial side, two-unit implant prosthesis without teeth on the distal side, three-unit implant prosthesis without teeth on the mesial side, and three-unit implant prosthesis without teeth on the distal side were designated as A, B1, B2, C1, and C2, respectively. The misfit for each scan body was calculated and the accuracies were compared using the Tukey–Kramer method. Results The average scan-body misfit for conditions A, B1, B2, C1, and C2 was 40.5 ± 18.9, 45.4 ± 13.4, 56.5 ± 9.6, 50.7 ± 14.9, and 80.3 ± 12.4 μm, respectively. Significant differences were observed between the accuracies of A and B2, A and C2, and C1 and C2 (P Conclusions IOS and CAD/CAM can find clinical applications for implant-supported prostheses of up to three units for a bounded edentulous saddle. The use of IOS could render implant treatment easier, benefiting both the surgeons and patients. Prosthesis maladjustment may lead to peri-implantitis and prosthetic fracture. Therefore, further validation of the accuracy of IOS impressions is required in patients with multiple missing teeth in long-span implant prostheses.

Background There is a growing tendency to place single tooth implants immediately after extracting a failing tooth in the posterior region. The aim of this prospective case series pilot study was to evaluate immediate implant placement in molar post-extraction sites during a 1-year follow-up period. Materials and methods Fifteen consecutive patients with a single failing molar in the maxilla or mandible, and presenting enough bone to expect primary implant stability and an implant site free of infection, were included. The implants, with a large thread depth and sharp thread edges, were placed in each patient according to a two-staged surgical procedure. Three months later, a full contour screw-retained zirconia restoration with an angulated screw channel abutment was provided. Clinical and radiographic examinations were performed 1 month and 12 months after placing the restoration. In addition, the patients’ satisfaction with the restoration was scored after 12 months. Results Four out of 15 of the mobile implants had to be removed before the 1-year evaluation. The implant and restoration survival rates were 73.3% at the 1-year evaluation (n = 15). The mean marginal bone loss, from loading to the 12-month follow-up, was 0.17 mm (n = 11). The mean plaque, calculus, peri-implant mucosa, bleeding, and pocket probing depth scores were low, depicting healthy peri-implant conditions. The patients were very satisfied. Conclusion It was demonstrated, within the limitations of this study, that immediate placement of regular diameter implants in molar post-extraction sites in the maxilla and mandible resulted in a high implant failure rate during a 1-year follow-up period.

To compare the active tactile sensibility (AST) between natural teeth and implant dentures, and explore the risk factors. To establish a database of normal tactile thresholds of natural teeth, and integrate the results from experiments. 50 patients underwent posterior dental implant restoration. A healthy group was also enrolled as control. Patients were firstly placed in semi-supine position with soothed tension and wore ear pads and goggles. Next, T-scan II digital occlusal analysis system (Tekscan,USA). The test was performed in double-blind way and recorded by the third. Results were analyzed using SPSS software and P value less than 0.05 was considered as statistically significant. Active tactile sensibility showed no statistically significant difference between natural teeth and dental implants among males and females (P > 0.05). However, there was difference between the natural tooth and implant tooth (P < 0.01), and there was also statistically significant difference between the front tooth and the back of the natural tooth and implant tooth (P < 0.01). There is no significant difference in the determination of the active tactile sensitive threshold difference between the implanted tooth and the natural tooth, which could serve as a comprehensive guiding for clinical strategies of tooth implantation.

Aim: To evaluate the loss of applied torque (detorque) values in cast and pre-machined abutments for external hex abutment/implant interface of single implant-supported prostheses subjected to mechanical cycling. Methods: Ten metal crowns were fabricated using two types of UCLA abutments: cast and pre-machined with metal base in NiCrTi alloy and tightened to regular external hex implants with a titanium alloy screw, with an insertion torque of 32 N.cm, measured with a digital torque gauge. Samples were embedded with autopolymerizing acrylic resin in a stainless steel cylindrical matrix, and positioned in an electromechanical machine. Dynamic oblique loading of 120 N was applied during 5 x 105 cycles. Then, each sample was removed from the resin and detorque values were measured using the same digital torque gauge. The difference of the initial (torque) and final (detorque) measurement was registered and the results were expressed as percentage of initial torque. The results of torque loss were expressed as percentage of the initial torque and subjected to statistical analysis by the Student’s t-test (p

Background Assessment of the subjective experiences of individuals with maxillary anterior (ie, the upper front region of the mouth) single-tooth implants is limited mainly to quantitative measurements of satisfaction with appearance. Interestingly, there is unexplained variability in the relationship between satisfaction and appearance. Objective This qualitative study protocol aims to explore and better understand the satisfaction with appearance and function in a Canadian population with maxillary anterior single-tooth implants treated at a postgraduate university clinic. Thus, we aim to obtain diversity among participants relating to the identification of esthetically pleasing and displeasing cases from a clinician perspective. Methods A qualitative research design using interpretative phenomenology analysis (IPA) will provide an adaptable inductive research approach. The participants will be recruited, and consent documents, photographs, digital intraoral scans, and self-administered questionnaire responses will be obtained from them. The transcribed verbatim data from audio-recorded, in-depth, semistructured, one-to-one interviews of the participants will be managed, coded, and analyzed thematically with computer-assisted qualitative data analysis software. The IPA will consider the COnsolidated criteria for REporting Qualitative (COREQ) guidelines when applicable. Results For the qualitative interview, we plan to include at least eight patients to conduct up to 1.5 hours of open-ended interviews with each participant aided by an interview guide. Ethical approval was granted by the University of British Columbia Behavioral Research Ethics Board (H19-00107) in May 2019. Two American dental foundations funded this study. Conclusions The analysis in this study will elucidate the aspects (including their value) that influence participant satisfaction at different dental implant treatment stages. This will be the first qualitative study on this group of the population to explore and obtain a better understanding of their satisfaction with appearance and function, as well as any other patient-reported outcome measures that could be identified.

Purpose: The purpose of the study was to compare delayed and early loaded single-tooth implant technique. Materials and Methods: A randomized, prospective clinical trial was conducted to evaluate the clinical and radiological parameters of delayed and early loading of single-tooth implant placement. Fourteen male or female patients were selected randomly, who had single tooth missing in mandibular posterior region. A delayed implant placement technique was followed in these regions. A Hi-Tech implant (Life Care Implants) was performed. The patients were divided into two groups: delayed loading group and early loading group. In delayed loading groups, implants were loaded after 3 months, and in early loading groups, implants were loaded within 7 days to 2 months. Soft tissue and radiological bone loss were assessed at baseline, 3 months, and 6 months. The parameters assessed were plaque index, gingival index, probing pocket depth, thickness of peri-implant mucosa, and bone loss (radiographically). Results: The results show that there was no statistical difference in indexes taken between delayed loading and early loading groups. Conclusion: In this study, after first 6 months there was no difference in success rate between delayed loading or early loading of implants. This study also showed that more bone loss occurred around delayed loading implants. So it can be concluded that early loading technique can be successfully practiced instead of delayed loading of implants.

The predictability of aesthetic success depends on the tissue loss present at the initiation of treatment. Replacement of single as well as multiple missing teeth in the aesthetic zone is challenging particularly when the three dimensional architecture of the existing bone and soft tissue is deficient. The bony housing in this instance would require augmentation to provide a configuration that permits placement of implants in optimal positions which in turn would result in pleasing aesthetics. The purpose of this case report is to evaluate the stability and aesthetics of a single tooth implant placed in the anterior maxillary region with a bony defect through grafting of autogenous bone and use of a growth factor.

- Abstract
Aims and objective: The aim of the study is to evaluate clinically and radiographically the long term success of one-stage direct (lateral) sinus lift procedure using alloplastic bone graft material and bio-absorbable membrane in conjunction with two stage implant placement in atrophic partially edentulous posterior maxilla. Materials and methods: One stage direct maxillary sinus lift in conjunction with two stage implant placement was carried out in 12 patients at 13 sites. All the patients were partially edentulous with posterior maxillary alveolar ridge height of >5 mm and were in the age group of 20-50 years. Bioactive glass putty, bio-absorbable collagen membrane and 3.75 × 11.5 mm implants were used. Loading of implants was done 6 months after placement of implants. Patients were evaluated clinically and radio-graphically 6, 18, 30 months after placement of implants to assess increase in residual ridge height, peri-implant condition (marginal bone loss, plaque and gingival index) and implant stability. Results: Maxillary first molar was the most common site (69.23 %) for sinus lift and implant placement. Caries was the most common cause (76.92 %) for loss of tooth. Increase in residual ridge height ranged from (71.43 to 133.33 %) as measured by Denta-Scan. Implant survival rate was 100 %. Marginal bone loss ranged from 0.68 to 1.22 mm. Implant stability was measured by periotest (−2.7 to −3.6). Only one patient had perforation of sinus membrane, but it was sealed satisfactorily by bio-absorbable membrane. Conclusion: One stage lateral sinus lift procedure with alloplastic bone graft material in combination with 2 stage implant placement has a predictable outcome in patients with severe resorption of posterior maxilla.

- Abstract
The objective of this study was to assess the ability of the University of Illinois at Chicago College of Dentistry (UIC-COD) predoctoral students to provide single tooth implant (STI) prostheses in the maxillary esthetic zone. The patient's esthetic satisfaction and the correlation between prosthodontists' and patients' perspectives were examined. Twenty-seven patients were recruited for recall examinations at the UIC-COD predoctoral implant program and underwent clinical and radiographic examina-tion with clinical photographs of the implant sites. The patients completed a semantic differential scale questionnaire. The col-lected information was formulated into a PowerPoint presentation for two Diplomate of the American Board of Prosthodontists to use the Pink/White Esthetic Score (PES/WES) to evaluate the esthetic outcome. Descriptive analyses, Cohen kappa test, and Spearman rank correlation coefficient test were performed. The average PES/WES were above 6.0 (out of 10). The median for the patient satisfaction and esthetic outcome questionnaires were 10 and 9, respectively, on a scale with 10=highest. There was a medium and positive correlation between prosthodontists' and patients' perspectives in esthetic outcome. This study found that, with strict guidance and proper selection criteria, predoctoral students were able to provide esthetically acceptable STI prostheses in the maxillary esthetic zone and patients were satisfied with the treatment provided.

Objective: Over the last decades, techniques and materials have evolved with the improvement in digital technology. Computer-aided impressions have been transforming the dental implant field with these developments. The aim of this in vivo study was to compare the accuracy and time efficiency between two intraoral scanning systems in single tooth implant treatment. Material and Method: 10 patients with single tooth bone level implant (Straumann, Basel, Switzerland) received one conventional impression with polyvinyl siloxane and three scans with 2 different intra-oral scanners (CEREC AC Omnicam and Straumann CARES IOS). The time required for the impressions was measured at this stage. The casts obtained from conventional impressions were scanned as the master model to evaluate accuracy. Digital impression files were analyzed using software (Geomagic Control). Independent Samples Test was performed for trueness and precision. One-way ANOVA was executed for time efficiency. Least significant difference test for post hoc comparison was conducted (p0.05), but a statistically significant difference was found in the time efficiency (P

Purpose: To evaluate the effectiveness of static computer-aided surgery technique with the conventional freehand method to assess the role of the surgical template in terms of duration of operation and postoperative pain levels. Methods: Total of 26 implants were placed: 13 using tooth-supported surgical templates; and 13 using the conventional freehand method. Duration of the surgery was recorded for all operation sites. After implant insertion, all patients were asked to evaluate two separate visual analog scales (VAS) at regular intervals for 1 week. All patients underwent cone beam computed tomography (CBCT) evaluation to assess the depth of deviation of the planned and placed implants. Results: the deviation of implants inserted using the computer-aided surgical technique and conventional freehand technique demonstrated no significant differences (P < 0.05). However, the computer-aided surgery technique significantly decreased the duration of the surgery and post-op pain levels. Conclusion: Tooth supported surgical templates had no particular effect on the accuracy of single implant placement. Nevertheless, this procedure allows flappless surgery with minimal invasive approach, reduce operation time and post-op pain levels. If further studies with larger study samples confirm the abovementioned results, surgical templates may be recommeded even in patients with single tooth loss. (C) 2019 Elsevier Masson SAS.

Objectives 1. To provide information about the subgingival microbiota around single tooth implants.2. To assess the subgingival microbial flora around the teeth adjacent to single tooth implants.3. To clinically evaluate the gingival health surrounding the single-tooth implants. Methods Patients undergoing the single-tooth implant replacements, were selected as subjects for the study. The natural teeth adjacent to implant sites were taken as control sites. Clinically each peri-implant gingival tissue health was evaluated. Subgingival plaque samples were removed with sterile curette and evaluated for microbial flora, by microscopic examinations. Bacterial cultures of samples studied. The similar procedure was followed for the control sites also. Finally the data collected were statistically analyzed and interpreted. Results The subgingival microbiota around single tooth implants was cultured and studied. Enterobacter species, Klebsiella pneumonia, Pseudomonas aeruginosa and Streptococcus species were predominantly found. Klebsiella pneumonia and Pseudomonas aeruginosa were found more frequently around implant sites than control sites. Anaerobic Bacteroides species were found in only one case around the implant site. Conclusions Prevention and control of bacterial infection in the peri-implant region are among the key factors in determining the long term success or failure of dental implant therapy. The thorough knowledge about the subgingival microbiota around the healthy and diseased peri-implant mucosa is needed to determine the overall outcome of implant therapy.

Replacing a single tooth in the anterior maxilla is one of the greatest challenges in dentistry. Both functional and aesthetic results are to be strictly pursued. Planning and executing such a case through a totally digital methodology eventually guarantee many advantages, above all patient’s operative and postoperative comfort. To ascertain this, a BOP analysis was performed which allowed us to evaluate soft tissues health, and more; crestal bone resorption was measured to evaluate hard tissues stability. This assumption was studied through four cases in which patients were alternatively treated with analogic and digital techniques. Four homogeneous patients were recruited. They all needed to extract one of the upper incisors, due to different clinical reasons, and then to replace it with an implant. Each patient was treated with an immediate postextractive implant which was immediately loaded, and finally, analogical and digital techniques were compared. All patients underwent a preoperative CBCT examination. After surgery, patients were checked by the surgeon after 10 days and one month to evaluate the progress of healing and to exclude any prosthetic problem. At 6 months (T1), one year (T2), and three years (T3), intraoral x-rays were performed using customized centring devices, according to the parallel beam technique. All data have been collected in a table and statistically processed; mean and standard deviation were measured. All patients entered an oral hygiene program with six months recall. Dental hygienist checked the BOP at T1, T2, and T3. At every step, similar levels of BOP were recorded. About interproximal bone loss, all patients showed an initial moderate loss (between T1 and T2), followed by stable values between T2 and T3. Despite the important limitations of a study with few cases, these results show a similar outcome comparing digital and analogical methods.

This study evaluated the von Mises stress (MPa) and equivalent strain occurring around monolithic yttria-zirconia (Zir) implant using three clinically simulated finite element analysis (FEA) models for a missing maxillary central incisor. Two unidentified patients' cone-beam computed tomography (CBCT) datasets with and without right maxillary central incisor were used to create the FEA models. Three different FEA models were made with bone structures that represent a healed socket (HS), reduced bone width edentulous site (RB), and immediate extraction socket with graft (EG). A one-piece abutment-implant fixture mimicking Straumann Standard Plus tissue level RN 4.1 X 11.8mm, for titanium alloy (Ti) and Zir were modeled. 178 N oblique load and 200 N vertical load were used to simulate occlusal loading. Von Mises stress and equivalent strain values for around each implant model were measured. Within the HS and RB models the labial-cervical region in the cortical bone exhibited highest stress, with Zir having statistically significant lower stress-strain means than Ti in both labial and palatal aspects. For the EG model the labial-cervical area had no statistically significant difference between Ti and Zir; however, Zir performed better than Ti against the graft. FEA models suggest that Ti, a more elastic material than Zir, contributes to the transduction of more overall forces to the socket compared to Zir. Thus, compared to Ti implants, Zir implants may be less prone to peri-implant bone overloading and subsequent bone loss in high stress areas especially in the labial-cervical region of the cortical bone. Zir implants respond to occlusal loading differently than Ti implants. Zir implants may be more favorable in non-grafted edentulous or immediate extraction with grafting.

Aim: To evaluate the loss of applied torque (detorque) values in cast and pre-machined abutments for external hex abutment/implant interface of single implant-supported prostheses subjected to mechanical cycling. Methods: Ten metal crowns were fabricated using two types of UCLA abutments: cast and pre-machined with metal base in NiCrTi alloy and tightened to regular external hex implants with a titanium alloy screw, with an insertion torque of 32 N.cm, measured with a digital torque gauge. Samples were embedded with autopolymerizing acrylic resin in a stainless steel cylindrical matrix, and positioned in an electromechanical machine. Dynamic 5 oblique loading of 120 N was applied during 5 x 10 cycles. Then, each sample was removed from the resin and detorque values were measured using the same digital torque gauge. The difference of the initial (torque) and final (detorque) measurement was registered and the results were expressed as percentage of initial torque. The results of torque loss were expressed as percentage of the initial torque and subjected to statistical analysis by the Student's t-test (p<0.05) for comparisons between the test groups. Results: Statistical analysis demonstrated that mechanical cycling reduced the torque of abutments without significant difference between cast or pre-machined UCLA abutments (p=0.908). Conclusions: Within the limitations of this in vitro study, it may be concluded that the mechanical cycling, corresponding to one-year use, reduced the torque of the samples regardless if cast or pre-machined UCLA abutments were used.

AIM: The present article aims to provide a few yet simple steps which will be clinically helpful in placement of the pontic. BACKGROUND: The healing period after implant placement is generally 3-4 months and the appearance of a gap from a missing tooth can be a concern, especially if it is in the display zone of a patient's smile. If the treatment plan includes prosthetic replacement of the missing tooth rather than space closure, then space maintenance is also an issue. TECHNIQUE: This article describes a clinically helpful technique for the placement of riding pontic. CONCLUSION: The technique described here is simple, easy and inexpensive. CLINICAL SIGNIFICANCE: Riding pontics are alternative cosmetic option which helps to improve esthetics and the smile during orthodontic treatment and contribute to the psychological well being of the patient of any age.

In the anterior region, the common reason for tooth loss is due to traumatic injury or congenital anomaly. Loss of a single tooth may cause functional and esthetic deficits to the patient. There are different treatment options available for replacing a missing incisor. Implant dentistry should be considered as first treatment alternative for replace a missing tooth. This case report presents the replacement of a missing maxillary left central incisor in a compromised site with dental implants along with bone graft followed by frenectomy to obtain a good clinical result and for better function and esthetics of the patient.

MAXILLA , *ARTIFICIAL implants , *OSTEORADIOGRAPHY - Abstract
According to the standard protocol, a load-free healing period is one of the most emphasized requirements for implant integration. Recent studies have encouraged a progressive shortening of the healing period for single-tooth implants and immediate loading has been proposed for the aesthetic zone in the maxilla. The present study evaluated clinical outcomes of immediately loaded FRIALIT-2 Synchro implants 12 months after placement in the maxillary incisal region. In the course of our investigation, nine patients have been treated following an immediate loading protocol. The stepped-screw type implants were inserted with an increasing torque up to 45 Ncm, thus measuring the primary stability of the implants. All implants were immediately restored with unsplinted acrylic resin provisional crowns and the patients provided with occlusal splints. Regular controls were performed at monthly intervals, intraoral radiographs were taken directly after implant placement, 6 and 12 months post insertion. The survival rate, clinical stability (Periotest) and radiographic coronal bone defects (CBD) were evaluated at delivery of the definitive superstructures (CBD 6) and 6 months later (CBD 12). Twelve FRIALIT-2 Synchro stepped screws of 3.8, 4.5 and 5.5 mm diameter and 13 and 15 mm length were placed in the incisal maxillary region. The median Periotest value 6 months post insertion was -2 with a minimum of -5 and a maximum of +2. The mean coronal bone level changes (CBD) at 6 and 12 months were 0.45 and 0.75 mm. No implant failed up to 12 months after insertion, resulting in a 100% survival rate. The presented results showed promising data for immediately loaded single-tooth implants in the anterior maxilla. Periotest values were within the range published for submerged implants. The radiographic coronal bone resorption after 6 and 12 months was even less than evaluated for implants placed in a standard two-stage procedure. It is evident that successful immediate loading...

The objective of this study was to evaluate the factors influencing the willingness to pay for a single tooth implant in Malaysia and to assess if an additional evidence-based patient education video increases the willingness to pay. A total of 100 subjects seeking single tooth replacement at the Oral Health Centre, International Medical University (IMU), Kuala Lumpur, Malaysia, were asked to complete questionnaires about personal demographics and personality traits. Subsequently, they were randomly allocated into two groups. Group C received a conventional patient–dentist interaction on treatment options for missing teeth, while Group EV received the same content with an additional evidence-based video on the survival rate and complications for each option from recent meta-analyses. Willingness to pay the median price and the highest price that the subjects were willing to pay were assessed by a structured bidding process. A higher annual income was significantly associated with willingness to pay the median price for a single tooth implant (χ
2 = 6.91, p = 0.03). Dominant personality traits of openness (r = −0.25), conscientiousness (r = −0.30) and agreeableness (r = −0.20) were negatively correlated with the highest price that the patients were willing to pay for a single tooth implant (Pearson's correlation test, p < 0.05). No significant difference in willingness to pay was found between Group C and Group EV (χ2 = 0.05, p > 0.05). In conclusion, patient education strategies for single tooth replacements with dental implants should be customized based on a patient's personality and income to maximize effectiveness.

Background: This study aims to assess, with regard to marginal bone level (MBL), whether the outcome of immediate implant placement in bony defects in the esthetic zone was non-inferior to delayed implant placement after 1 year.Methods: Forty patients with a failing tooth in the esthetic zone and a labial bony defect of >= 5 mm after removal of a tooth were randomly assigned for immediate (n = 20) or delayed (n = 20) implant placement. Second-stage surgery and provisionalization occurred after 3 months of healing. Follow-up was at 1 month and 1 year after definitive crown placement. The study was powered to detect a difference in MBL of >0.9 mm. Buccal bone thickness, soft tissue peri-implant parameters, esthetic indices, and patient satisfaction were also assessed.Results: One year after definitive crown placement, MBL loss was 0.56 +/- 0.39 mm mesially and 0.74 +/- 0.51 mm distally for the immediate placement group and 0.51 +/- 0.43 mesially and 0.54 +/- 0.45 distally mm for the delayed placement group, respectively (not significant). Regarding differences in means, non-inferiority was observed after 1 year (difference in mean for immediate versus delayed: mesially 0.04 mm [95% confidence interval (CI) = -0.22 to 0.30 mm, P = 0.40]; distally 0.21 mm [95% CI = -0.10 to 0.51 mm, P = 0.58]). No significant differences in the other outcome variables were observed.Conclusions: Immediate implant placement with delayed provisionalization was non-inferior to delayed implant placement with delayed provisionalization in labial bony defects of >= 5 mm regarding change in MBL. Although not powered for other outcome variables, no clinically relevant differences were observed in these variables.

From January 1992 to March 1997, a total of 30 ITI hollow cylinder implants were installed to replace lost single maxillary incisor teeth. Conical abutments with cemented all-ceramic crowns were used in 10 cases and the Octa-abutment with screw-retained metallo-ceramic crowns in 19 cases. One implant failed due to postoperative infection, and was extracted a month after installation. After a mean observation time of 3.4 years, the cumulative success rate is 96.7%. Only minor bone loss has occurred around the implants, and there have been no other complications to date. The implant system fulfills the requirements for good function 1 and esthetics.

To test whether or not pink veneering of the submucosal part of zirconia abutments influences clinical, microbiological and histological outcomes of cemented implant-supported single crowns (ISSC).A total of 20 patients with one single-tooth implant in the esthetic zone were included. Implants were randomly restored with either pink-veneered zirconia abutments (test group; n = 10) or non-veneered white zirconia abutments (control group; n = 10) and with adhesively cemented all-ceramic crowns. At the 6-month follow-up, soft tissue biopsies were prepared for histological evaluation and microbiological samples were collected around abutments and the respective contra-lateral teeth (in 10 of 20 patients). One year after the initiation of loading, clinical parameters were assessed. Robust linear mixed model and cumulative linked mixed model analyses were performed to investigate the effect of group and time-point on clinical and biological outcomes.Clinical evaluations revealed stable peri-implant soft tissues in terms of probing pocket depth, but a high BOP index (87.5% control; 80.0% test). No statistically significant differences were observed between the test and control group for any outcome measure (P 0.05). No major biological complications occurred during the observation period. Histological samples revealed a remarkable degree of inflammation in both groups without clear differences in qualitative histological features. Microbiological evaluation demonstrated a slightly higher bacterial count at implants compared to natural teeth at one year of loading without marked differences between groups.Limited by a small sample size and a relatively short observation period, pink-veneered zirconia abutments exhibited similar clinical, histological and microbiological outcomes as non-veneered zirconia abutments supporting cemented single crowns.

To assess whether outcome of immediate implant placement and immediate provisionalization after 1 year was non-inferior to immediate implant placement and delayed provisionalization regarding Marginal Bone Level (MBL).Forty patients with a failing tooth in the aesthetic zone were randomly assigned for immediate implant placement with immediate (n = 20) or delayed (n = 20) provisionalization. Follow-up was at 1 month and after 1 year. The study was powered to detect a difference in MBL of0.9 mm. Apart from MBL, soft tissue peri-implant parameters, aesthetic indexes and patient satisfaction were assessed.After 1 year, MBL changes were -0.75 ± 0.69 mesially and -0.68 ± 0.65 distally mm for the immediate group and -0.70 ± 0.64 and -0.68 ± 0.64 mm for the delayed group respectively (NS). Regarding differences in means, non-inferiority was observed after 1 year (mesially: Group A versus B: difference in mean 0.08 mm (95% CI -0.38 to 0.53, p = 0.71 distally: Group A versus B: difference in mean 0.09 mm (95% CI -0.37 to 0.56 mm, p = 0.66).No significant differences in the other outcome variables were observed.This study showed that immediate placement and immediate provisionalization was non-inferior to immediate placement with delayed provisionalization. In addition, although not powered for these outcome variables, no clinically relevant differences in other outcomes were observed (www.isrtcn.com: ISRCTN57251089).

This prospective study assessed patient satisfaction before and after single-tooth implant therapy in the esthetic zone. Before implant therapy, patients wore an acrylic resin tissue-supported removable partial denture (RPD). A total of 153 patients were included. Self-administered questionnaires regarding function, comfort, and esthetics were used to measure patient satisfaction with the RPD and with the implant at 6 and 18 months post-implant placement. Overall satisfaction was explored with a visual analog scale. It was suggested that patient satisfaction with a single-tooth implant in the esthetic zone is high and it improved when compared with an RPD that patients wore before implant treatment.

As the aesthetic demands are increasing day by day, demand of immediate restoration or replacement of teeth is also increasing. Because of this, immediate implant placement, along with immediate loading of implant, is a favourite treatment option for patients as well as dentists. This case report discusses the immediate implant loading in compromised maxillary anterior region, in which patient got immediate restoration of edentulous area. More importantly, from the patients’ points of view, immediate loading can produce positive social and psychological effects.

The aim of this study was to test whether veneering of the submucosal part of zirconia abutments using pink veneering ceramic positively influences the color of the peri-implant mucosa. Single-tooth implants were restored with either white zirconia abutments (control group) or pink-veneered zirconia abutments and all-ceramic crowns. Esthetic outcome measurements included a spectrophotometric evaluation of the peri-implant mucosal color. Test and control groups induced a visible discoloration of the peri-implant mucosa after the insertion of the abutments and following cementation of the crowns compared to natural teeth. The calculated color differences were above the clinically visible threshold value and were more favorable for the control group, although not statistically significant. It is concluded that veneering of zirconia abutments with pink veneering ceramic failed to positively influence the esthetic outcome, mostly due to a decrease of the brightness compared with the control group.

ResumenPropósitoEl presente artículo es un estudio prospectivo de las tasas de éxito implantaria y de las complicaciones mecánicas y biológicas en el tratamiento rehabilitador implanto-asistido del sector posterior de la maxila, mediante provisionalización inmediata.Material y MétodoEl estudio clínico observó a 21 sujetos desdentados parciales unitarios del sector posterior maxilar, con reborde cicatrizado y antagonista dentario natural, por un período de 6 meses, en los que se insertaron implantes cónicos roscados de conexión interna, con tratamiento de superficie, temporizados inmediatamente después de insertados en el hueso maxilar, mediante la confección de una corona de resina acrílica sobre un pilar temporal de titanio atornillada directa al implante, dejados sin contactos dentarios durante la máxima intercuspidación (MIC) y movimientos excéntricos mandibulares. Todas las restauraciones fueron observadas durante un período de 6 meses, evaluando tasa de éxito implantario, complicaciones biológicas y mecánicas.ResultadosSe insertaron 25 implantes en 21 pacientes, obteniéndose un valor promedio de inserción de torque quirúrgico de 45.6 Nt. Durante el período de observación clínico se presentó un 100% de éxito de sobrevida implantario, no se detectaron complicaciones biológicas, pero sí se presentaron complicaciones mecánicas por fractura de una cúspide vestibular de una restauración provisional acrílica y dos aflojamientos de tornillos.ConclusionesLa temporización unitaria mediante provisorio atornillado es un protocolo predecible y confiable que permite el proceso de oseointegración y la coexistencia en salud de tejido periimplantario y su sistema protésico.AbstractPurposeThis article is a prospective study of implant success rates and of mechanical and biological complications in the assisted-implant rehabilitation treatment of the posterior maxilla by immediate temporization.Material and MethodsThe clinical study observed 21 partially edentulous subjects with lip scar and antagonistic natural teeth in the posterior maxilla for a period of 6 months in which conical threaded internal implant connections were inserted with a surface treatment and timed immediately after being inserted into the jawbone by producing an acrylic resin crown on a temporary titanium abutment screwed directly into the implant and left without tooth contacts during the Maximal Intercuspal (MIC) and mandibular eccentric movements. All restorations were observed over a period of 6 months evaluating implant success rate and biological and mechanical complications.Results25 implants were inserted into 21 patients yielding an average surgical insertion torque of 45.6 Nt. During the clinical observation there was 100% success of implant survival. No biological complications were detected, but there were mechanical complications - a buccal cusp fracture of an acrylic provisional restoration and two screws loosening.ConclusionsThe unit temporization by temporary screwing is a predictable and reliable protocol that allows osseointegration and the coexistence in the health of peri-implant tissue and its prosthetic system.
