Background and Objectives: Oral rehabilitation seeks to enhance mastication, a vital component of oral function that is compromised by tooth loss. This study aimed to assess the degree of improvement of masticatory performance in partially edentulous patients rehabilitated with removable partial dentures (RPD) or fixed partial dental prosthesis (FPDP). Changes in the occlusal contact area (OCA) and satisfaction with their chewing ability during the adaptation period were also evaluated. Materials and Methods: in total, 34 partially edentulous participants (median age 65.3 years; 56% women) who received an RPD or FPDP were assessed using masticatory performance assay, OCA calculation, and a visual analog scale (VAS). Results: Masticatory performance improved by 20% (range from 17% to 25%, p < 0.05) depending on the edentulism and the rehabilitation types. The OCA improved by 4.7 mm2 (p < 0.05) and satisfaction with the masticatory function improved by 9% (p < 0.05) 3 months after prosthesis insertion. Conclusions: Conventional prostheses benefited partially edentulous individuals, improving masticatory performance by 20%. Treatment also increased the OCA in all types of partial edentulism, except in Kennedy class I patients rehabilitated with RPD. Patients' satisfaction with their chewing ability only increased in Kennedy class III patients rehabilitated with RPD. [ABSTRACT FROM AUTHOR]

The patient was a 69-year-old male who had decreased VDO and overbite of the anterior teeth due to severe teeth wear. Complete mouth rehabilitation was planned to restore esthetics and function. Due to the presence of a subgingival finish line, poor fit of the margin of the temporary crown, and insufficient oral hygiene management, gingival overgrowth and bleeding occurred in many teeth, and inaccurate impressions were taken. After dividing each arch and taking partial impressions, a transfer coping was made using pattern resin on each working model die, and after being placed on the abutment teeth, a master cast was made through pick-up impression taking to produce prosthesis. In this case, the final prosthesis produced on the second master cast were fitted in terms of proximal contact, marginal fit, vertical occlusal dimension, facial appearance, esthetics, and occlusion. After complete mouth rehabilitation, the patient was satisfied with function and esthetic appearance. (J Korean Acad Prosthodont 2024;62:224-33) [ABSTRACT FROM AUTHOR]

Abstract Purpose Awake extubation and deep extubation are commonly used anesthesia techniques. In this study, the safety of propofol-assisted deep extubation in the dental treatment of children was assessed. Materials and methods Children with severe caries who received dental treatment under general anesthesia and deep extubation between January 2017 and June 2023 were included in this study. Data were collected on the following variables: details and time of anesthesia, perioperative vital signs, and incidence of postoperative complications. The incidence of laryngeal spasm (LS) was considered to be the primary observation indicator. Results The perioperative data obtained from 195 children undergoing dental treatment was reviewed. The median age was 4.2 years (range: 2.3 to 9.6 years), and the average duration of anesthesia was 2.56 h (range 1 to 4.5 h). During intubation with a videoscope, purulent mucus was found in the pharyngeal cavity of seven children (3.6%); LS occurred in five of them (2.6%), and one child developed a fever (T = 37.8 °C) after discharge. Five children (2.6%) experienced emergence agitation (EA) in the recovery room. Also, 13 children (6.7%) experienced epistaxis; 10 had a mild experience and three had a moderate experience. No cases of airway obstruction (AO) and hypoxemia were recorded. The time to open eyes (TOE) was 16.3 ± 7.2 min. The incidence rate of complications was 23/195 (11.8%). Emergency tracheal reintubation was not required. Patients with mild upper respiratory tract infections showed a significantly higher incidence of complications (P

Emergency tracheal reintubation was not required. Patients with mild upper respiratory tract infections showed a significantly higher incidence of complications (P < 0.001). Conclusions: Propofol-assisted deep extubation is a suitable technique that can be used for pediatric patients who exhibited non-cooperation in the outpatient setting. Epistaxis represents the most frequently encountered complication. Preoperative upper respiratory tract infection significantly increases the risk of complications. The occurrence of EA was notably lower than reported in other studies. [ABSTRACT FROM AUTHOR]

The influence of age and region of the mouth was assessed in regard to mouth opening in fully guided implant placement. Ninety patients were included in this study, 30 in each of three age groups (20–34, 35–55, and >55 years). Maximum passive mouth opening was recorded in three locations: incisal, canine, and molar. The minimum distance required to allow the bone drilling sequence through a static fully guided approach was analysed for four implant systems: Straumann, MIS Dentsply, Astra Tech Dentsply, and Dentium. The mean ± standard deviation maximum mouth opening (all 90 patients) was 46.34 ± 7.70 mm, 36.82 ± 5.92 mm, and 30.99 ± 5.40 mm in the incisal, premolar, and molar region, respectively. No significant difference in mouth opening at any of the three locations was found between the age groups (all P > 0.05). However, a correlation was found between increasing age and decreasing average mouth opening in all three mouth regions; each additional 1 year resulted in a mean reduction of 0.13 mm, 0.09 mm, and 0.08 mm in the incisal, premolar, and molar region, respectively. The minimum required mouth opening was most likely to be met for implant placement in the incisal region (98.9% of all patients) and least likely to be met for placement in the molar region, particularly for older patients (as low as 30% of patients). Mouth opening remains a major limitation in fully guided implant surgery, especially in posterior areas and in older patients. The use of some implant systems in the posterior area may be limited to only one in three patients. [ABSTRACT FROM AUTHOR]

ABSTRACT The Removable Partial Denture stands as an effective rehabilitation choice for patients who have undergone partial maxillectomy surgery due to maxillary tumors, involving the partial surgical removal of the maxillary bone. Removable partial denture are meticulously designed to restore masticatory, phonetic, and aesthetic functions, thereby contributing significantly to enhancing self-esteem and aiding patients in resuming social activities. During the patient’s history-taking phase, it is of paramount importance to assess the patient’s overall health, psychological state, expectations, and limitations. Ensuring regular follow-ups is imperative to prevent complications and to guarantee the durability of the prosthesis. Prosthetic planning constitutes a critical phase and can pose challenges, especially in achieving proper retention, stability, and suitable supports. Factors such as the defect size, the number of remaining teeth, and the amount of remaining bone structures can influence the treatment prognosis. It is crucial to emphasize that lack of adequate planning can lead to rehabilitation failures, resulting in discomfort, compromised functionality, and even potential harm to the patient’s health. In this context, this study aims to present a successful clinical case of a patient who underwent partial maxillectomy and was rehabilitated through a Removable Partial Denture fixed with clasps on the entire left upper hemi-arch. This case vividly illustrates the importance of a personalized approach to prosthetic rehabilitation in patients with partial maxillectomy, taking into account the specificities of each case and highlighting the necessity of interdisciplinary collaboration to achieve satisfactory outcomes.

Results: Masticatory performance improved by 20% (range from 17% to 25%, p < 0.05) depending on the edentulism and the rehabilitation types. The OCA improved by 4.7 mm2 (p < 0.05) and satisfaction with the masticatory function improved by 9% (p < 0.05) 3 months after prosthesis insertion. Conclusions: Conventional prostheses benefited partially edentulous individuals, improving masticatory performance by 20%. Treatment also increased the OCA in all types of partial edentulism, except in Kennedy class I patients rehabilitated with RPD. Patients’ satisfaction with their chewing ability only increased in Kennedy class III patients rehabilitated with RPD.

The objective of this study is to present a surgical approach to reactive lesions for rehabilitation purposes in an elderly patient. A 63-year-old male patient presented to the dental clinic of a higher education institution reporting swelling in the inner/upper part of his mouth, as well as aesthetic dissatisfaction when smiling. During the medical history, he reported that he had used the prosthesis for approximately 5 months but stopped using it continuously due to severe pain in the areas corresponding to the "edges" of the prosthesis, but he did use it while chewing. On intraoral examination, lesions with a hyperplastic appearance could be highlighted in the fundus of the vestibule of the upper arch bilaterally. Based on the clinical characteristics presented, it was decided with the patient to remove the lesions surgically, followed by referral for prosthetic rehabilitation. The fragments were removed and sent for confirmation of the condition, confirming the hypothesis of reactive fibroepithelial hyperplasia. The patient was then referred for prosthetic rehabilitation. Surgical approach for conditioning of gingival tissue prior to rehabilitation treatment is, therefore, a viable option with a good prognosis when it comes to a reactive lesion, making the environment suitable for the installation of removable prostheses.

The defect in the Velopharyngeal (VP) valve leads to problems in speech and swallowing. Such defects can be managed either by surgical means or palatal obturator. Fabrication of obturator in edentulous patients presents many challenges like lack of retention and support leading to functional compromise of a prosthesis. This case report describes the rehabilitation of a geriatric patient who was surgically treated for mucoepidermoid carcinoma of the hard and soft palate. After surgery, the patient complained of nasal regurgitation of food and hypernasal speech. A wrought wire in a zigzag shape was used to attach the pharyngeal obturator to the maxillary overdenture for better retention and support of the prosthesis. [ABSTRACT FROM AUTHOR]

Systemic scleroderma is a relatively rare, autoimmune, chronic, and debilitating disease, and its etiology is unknown. The disease is characterized by vasomotor disturbances causing skin and mucosa hardening, hand stiffness, excess production of collagen fibers, and impairment of the internal organs associated with the immune system. Extreme mouth-opening limitation is one of the symptoms in the oral cavity, and compromises dental intervention. One of the fundamental steps when performing a dental procedure is dental arch impression. In the presented clinical case, limited mouth opening hindered the impression accuracy. The objective was to present an alternative impression technique for a patient affected by scleroderma, with limited mouth opening and the need for oral rehabilitation with a removable partial prosthesis in the maxillary arch. An individualized tray was developed with design characteristics that allowed access to the oral cavity and removal, after which it was possible to perform the oral impression, reproducing the areas of interest without causing injury to the oral tissues. The orientation plan was elaborated after obtaining the cast. The teeth were assembled, tested in the mouth, and sent to the laboratory for acrylization. The prosthesis was placed once ready. The alternative impression technique enabled oral rehabilitation of the patient despite the mouth-opening limitation, and provided an accurate impression and a good prosthetic result.

Background: The literature is unclear about bite force (BF) and handgrip force (HF) in a specific group of different ages and dentate conditions, or even a predictive model for each specific group, using BF and HF as factors. Objective: To establish the correlation between HF and BF in female participants with distinct ages and dentate conditions; also create a predictive model of BF as a function of HF. Methods: Participants were divided into three groups (GI: young natural dentate women, n = 65; GII: adult natural dentate women, n = 67; and GIII: edentulous women users of bimaxillary complete dentures, n = 67) and subjected to an HF measurement test using a digital dynamometer. Subsequently, BF was measured using a digital gnathodynamometer in the molar region. Pearson correlation coefficient (r) and multivariate analysis of variance (α = 0.05) were performed, and simple linear regression was used to obtain a model to predict BF from HF for each group separately (α = 0.05). Results: All groups presented moderate and strong correlations among the variables (GI: r = 0.838; GII: r = 0.714; GIII: r = 0.646). A significant difference in BF was observed (GI > GII > GIII; p <.05). GIII presented a significantly lower HF than the other groups (p <.05). Besides, three equations predicting BF, using HF, were obtained for use in young/adult dentate and edentulous women. Conclusion: All groups found a positive and significant correlation between BF, HF and groups. HF can be a simple and efficient method for predicting BF using the predictive models developed for women with good health. [ABSTRACT FROM AUTHOR]

Abstract Background Progressive familial intrahepatic cholestasis is a heterogeneous group of disorders, leading to intrahepatic cholestasis, with the possibility of chronic liver failure and biliary cirrhosis. Oligodontia is either the manifestation of a specific syndrome or is non-syndromic. To the best of our knowledge, this is the first case report of type 3 progressive familial intrahepatic cholestasis and concurrent oligodontia, craniosynostosis, dens in dente, taurodontism, and delayed permanent dentition in the medical and dental literature. Case presentation We present the dental and medical histories and comprehensive dental management of a girl with type 3 progressive familial intrahepatic cholestasis and several dental anomalies, who was referred to a dental clinic due to severe dental caries and pain. Conclusion Our findings suggest that PFIC with manifestations as oligodontia, craniosynostosis, dens in dente, taurodontism, and delayed permanent dentition, might indicate an unknown syndrome; otherwise, the craniofacial anomalies are the manifestations of an independent disease coinciding with PFIC. Moreover, our case is a good example of the importance of timely medical and dental care in confining further health-related complications. The patient was able to ingest without any pain or discomfort after receiving proper dental management.

Introduction: Oral rehabilitation is a multidisciplinary process that involves the integration of various knowledge and clinical and surgical procedures to treat oral problems. Digital tools have been developed to optimize clinical time and increase accuracy, such as image overlay, known as Virtual Patient, allowing for a non-invasive treatment plan. Clinical Case Report: A 35-year-old male patient, dissatisfied with the aesthetics of his smile and presenting generalized incisal and occlusal wear, was diagnosed with loss of Vertical Dimension of Occlusion. Initial examinations were performed, including cone beam computed tomography, intraoral scanning, and standardized photographs. The DORA device was 3D printed and consists of three pieces: an upper plate, a screw, and a lower plate, which were individually produced. Using a dynamic virtual model of the patient, the reconstruction of dental guides and the detection of eccentric interferences generated by the prosthetic design were diagnosed using a semi-adjustable articulator. The final result was patient satisfaction in terms of aesthetics and function. Conclusion: Collaboration between the clinician, planning center, and laboratory within the digital workflow ensured agility and precision in the completion of a completely individualized and functional treatment.

Introduction: Peg teeth are incisors which mesio-distal incisal widths are smaller than the cervical widths. The significant reduced size and format of those teeth are often related to a distal migration of the maxillary central incisors and maxillary anterior diastema. The presence of bilateral canine guidance is recommended to obtain a balanced occlusion, as it promotes a single contact between the maxillary and mandibular canines on the working side, with no other horizontal contacts. In aesthetic reconstructions, dental ceramics present high resistance and optical properties that resemble natural teeth. Objective: The aim of this study is to report an aesthetic and functional rehabilitation of peg teeth and establishment of canine guidance with ceramic fragments and veneers. Case report: The 25-year-old female patient complained about her "sharp" teeth. Clinical examination revealed the presence of peg-shaped maxillary lateral incisors, diastema between maxillary central incisors, and absence of canine guidance. After patients digital smile design and in-office tooth bleaching, a study cast and diagnostic wax-up were obtained. Following mock-up and patients approval, dental preparations and impressions were performed. Lithium disilicate ceramics were fabricated and tried in mouth. Veneers were then bonded, followed by occlusal adjustments, finishing and polishing. Conclusion: Thus, the final result was a natural smile, integrating aesthetics and function after 1-year follow-up. [ABSTRACT FROM AUTHOR]

This report details the successful prosthetic rehabilitation of a 25-year-old male patient with Papillon Lefèvre Syndrome (PLS) using an implant-supported hybrid prosthesis. Six implants were placed in the maxilla, and four were placed in the mandibular arch. All implants were inserted axially (non-tilted) and were planned to be loaded after a healing period of 6 months. One implant failed due to graft loss during the healing phase, which was removed and the remaining implants were restored with a hybrid prosthesis after 6 months, using the delayed loading protocol. The patient was followed-up for four years and all the remaining implants successfully integrated and remained fully functional during this period. The prosthesis significantly improved the functional, aesthetic, and psychological well-being of the patient. This case report is the first of its kind to use only four axially placed implants for rehabilitation of a PLS patient with a successful four-year follow-up. [ABSTRACT FROM AUTHOR]

When the patient with class III malocclusion needs extensive oral rehabilitation due to multiple missing teeth, accurate diagnosis, and careful analysis, such as the patient's occlusal relationship, facial changes, and evaluation of the temporomandibular joint are essential. Orthognathic surgery is often performed for aesthetic improvement, depending on the patient's chief complaint. If it is not possible due to certain circumstances, partial aesthetic improvement can be achieved through minimal elevation of the vertical dimension. As this patient may have unexpected issues, such as temporomandibular joint disorder, oral habits like bruxism, and masticatory muscle tension, it was determined whether the patient could adjust to a reversible temporary removable partial denture. After this, the maxillary implant-supported fixed prostheses and the mandibular fixed prostheses were used to achieve stable posterior support and to partially improve the maxillary anterior esthetics. The patient was satisfied with the results both aesthetically and functionally. The prognosis is expected to be good if regular check-ups are conducted. [ABSTRACT FROM AUTHOR]

Introduction: Endosteal implants may be insufficient in treating complete edentulism in severe bone loss, such as advanced bone resorption, trauma, infection, intraoral pathologies, and traumatic tooth extractions. With the developing technology, in cases where bone quality and quantity are inadequate, treatment with custom-made subperiosteal implants also emerges as an alternative. Case: This case report examined the procedural steps and the six-month post-operative period while evaluating our edentulous patient who rehabilitated using endosteal and custom-made subperiosteal implants. Results: No resorption or mobility of the implants was detected in the 6th-month post-operative control of our complete edentulous case, which was rehabilitated using traditionally used intra-bone implants in the maxilla and subperiosteal implants in the mandible. Conclusion: One of the essential advantages of the subperiosteal implant system is that it provides fixed prosthetic treatment, especially in jaws with advanced bone atrophy. Correct case selection and appropriate surgical and prosthetic treatment will increase success. Keywords: Dental implantation; Endosteal; Mouth rehabilitation; Subperiosteal.

For full‐mouth rehabilitation of worn dentition, "diagnostic" interim restorations are required to reestablish the interocclusal relationship. It is important but challenging to transfer the interocclusal relationship and to map the basic form and contour of interim restorations to the final restorations. Alignment of interim restorations and working casts is difficult when using digital workflows because of a lack of consistent hard tissue reference points. The digital workflow presented in this study used a "3‐point sectional‐cast digital cross‐mounting method" to transfer the interocclusal relationship during full‐mouth rehabilitation. An intermediate cast was made with three interim restorations: one on an incisor and two on molars. The interocclusal relationship and occlusal morphologies of the diagnostic interim prostheses were transferred and aligned to working casts using the 3‐point sectional casts. [ABSTRACT FROM AUTHOR]

In recent years, vibrational devices have been introduced in order to reduce patient discomfort in some situations such as orofacial pain, orthodontic therapy, and injection of local anaesthetics. This article aims to review the clinical experience given by the use of these devices in local anaesthesia. The literature search was carried out on the main scientific databases for articles up to November 2022. Eligibility criteria were established, and pertinent articles selected. The results were classified by author, year, type of study, sample size and characteristics, purpose of use, type of vibrational device used, protocol used, and outcomes. Nine relevant articles were found. These are split mouth randomized clinical trials which evaluate the reduction in pain perception with different devices and different protocols of use in children, during procedures which require local analgesia by injection, compared with traditional local anaesthesia with premedication based on anaesthetic gels. Different objective and subjective scales of pain and discomfort perception were used. Although results are promising, some data, such as those relating to vibrational intensity and frequency, are not clear. Evaluations on samples varying by age and context of use are necessary to fully define the indications for this type of aid during oral rehabilitation procedures. [ABSTRACT FROM AUTHOR]

Objective: to present the radiographic clinical follow-up of the prosthetic rehabilitation of a patient with an atrophic mandible, with the installation of short implants associated with an implant of regular length. Method: case report of a completely edentulous patient with an atrophic mandible and a 6-year radiographic clinical follow-up conducted at the dental clinic of the Federal University of Piauí, Teresina, from February 2011 to January 2020. After collecting sociodemographic data, health records, clinical radiographic examinations, and prosthetic surgical planning, four dental implants were installed between the mental foramina. After three months, mini-conical abutments and a fixed prosthesis screwed onto the implants were installed and monitored every six months for a period of six years. Results: the clinical evaluation revealed tissue stability without significant peri-implant changes after the follow-up period. Radiographically, bone resorption was not observed around the implant. Stability of the prosthesis and absence of prosthetic complications were observed during the follow-up period. Conclusion: short implants associated with regular-length implants can be placed in the anterior region of an atrophic mandible for rehabilitation with fixed complete dentures.

ABSTRACT The immediate rehabilitation of the posterior region of the mandible with dental implants, expands the set of possible actions for the dental surgeon, in the face of tooth loss. The purpose of this study is to describe two cases of single rehabilitation of mandibular molars with hybrid internal tapered implants indicated for immediate loading in post-extraction socket, associated with the maintenance of the prosthetic and peri-implant space. Implants with macrogeometry and surface treatment (Hydrophilic) were used to optimize primary stability, as well as the type of internal connection and prosthetic abutments that allows better accommodation and healing of adjacent tissues, and protection of the bone graft. Different methodologies of surgical guides did not influence the final result. The predictability of associating techniques and components can be observed in the 2-year follow-up. The initial planning combined with the new technologies enable to achieve stable and functional final restorations.

Palatally impacted canines are usually challenging to treat in terms of both biomechanics and possible side effects. Different therapeutic approaches have been reported with or without the use of temporary anchorage devices, including the canine-first approach. Two groups of patients with palatally impacted canines were compared, observing their canine movement measured on consecutive CBCTs after three months of treatment. In the control group, impacted canines were treated with direct anchorage on miniscrews, and in the test group with indirect anchorage using a miniscrew-supported transpalatal arch. The primary outcome was the canine movement speed; the secondary outcome was the change in the root length of adjacent teeth. The median monthly apex speed was 1.05 mm in the control group (IR [0.74, 1.64]) and 0.72 mm in the test group (IR [0.27, 1.30]). The median monthly cusp displacement was 1.89 mm in the control group (IR [1.04, 2.84]) and 1.08 mm in the test group (IR [0.81, 1.91]). Approximately 50% of teeth adjacent to an impacted canine underwent a negative root length change of less than 1 mm in the majority of cases, but no significant differences were found in root length changes between groups. No statistically significant differences in the reported speeds were found, and no miniscrew failures were observed in either group. [ABSTRACT FROM AUTHOR]

Purpose: Multifocal motor neuropathy (MMN) is a rare immune-mediated neuropathy causing progressive, asymmetric weakness without sensory loss. Long-term administration of intravenous (IVIg) or subcutaneous (SCIg) immunoglobulins is the primary therapeutic approach. Despite this, therapy failure can result in a decline in strength, particularly in the hands, impacting daily activities. This review and case report presents the current literature on this complex dental and medical topic and explores the novel use of dental implants for full-mouth rehabilitation in MMN patients undergoing long-term IVIg therapy., Materials and Methods: A patient with MMN underwent 15 years of long-term treatment with intravenous immunoglobulin (IVIg), starting with an initial dose of 0.4 g/kg for 5 days every 4 months in 2008. The maintenance dosage of 0.2 g/kg as a single dose every 3 months was established as a long-term therapy. In 2017, the patient received a maxillary and mandibular complete-arch implant-supported prosthesis., Results: MMN showed no progression until the IVIg interval was extended to every 4 months in 2022. Significant deterioration in dental health resulted from a loss of right-hand dexterity, which affected toothbrush use and interproximal brushing, resulting in poor oral hygiene. Dental hygiene and dental health, which were not optimal anyway, were considerably worsened by the loss of dexterity in the right hand, which impaired the use of the toothbrush and the cleaning of the interdental spaces., Conclusion: Dental implants are a well-established treatment for edentulous patients, but their success in those with MMN requires careful consideration of oral health practices. Effective maintenance protocols and optimised prosthetic designs are crucial for long-term implant therapy success in MMN patients. Peri-implant diseases pose risks influenced by various factors. In the case of MMN and its neurological considerations, implications for dental implant provision warrant further exploration, considering clinical symptoms, therapy, and potential progression.

Introduction: The objective of a complete denture prosthesis is restoring aesthetics, comfort, and function by the replacement of missing dental and alveolar structures employing a stable prosthesis. Case Report: Many conditions can complicate the treatment plan and fabrication of a complete denture prosthesis. Complete denture fabrication in clinically compromised conditions is a challenging task for the dentist. In this clinical report, we present comprehensive management of a patient with denture-induced hyperplasia, flabby ridge, and severely resorbed edentulous ridge. The three-part strategy for management of the above-mentioned challenges can provide high-quality complete dentures, based on recognized prosthodontic principles. This first part will discuss the management of denture induced hyperplasia by elimination of the inflammation and excision of the lesion. Part two will cover management of the flabby ridge using a modified window technique for the impression of maxillary flabby tissues for an improved and controlled application of the impression material that is usually obtainable in dental practice. Part three highlights the rehabilitation procedure of the resorbed mandibular ridge using a functional impression technique with minimum soft tissue displacement and neutral zone arrangement of teeth to improve stability of the denture. Conclusion: rehabilitation of a patient with denture induced hyperplasia, flabby ridge, and severely resorbed edentulous ridges was successful.

ABSTRACT Rubinstein Taybi syndrome has a genetic origin in the chromosome 16. It has physical characteristics, delay in physical and mental development, and may present oral alterations. This paper aims to report a case of prosthetic rehabilitation of a patient with syndrome who, due to dental trauma, lost dental elements early. Female patient, 4 years and 7 months old, with loss of the deciduous maxillary central incisors. The data collection was carried out through anamnesis, clinical and complementary exams. After the diagnosis and the establishment of the treatment plan, we made a Denari type prosthesis. It has a tube-bar mechanism that allows maxillary growth and development. At the end of treatment, the caregiver was instructed to make periodic visits to the dentist for clinical and radiographic follow-up of the prosthesis, as well as the need for treatment with the speech therapist. The loss of anterior deciduous teeth can be associated with trauma in this region and the dental absence can affect the development and behavior of children, promoting a change in daily life and impacting the quality of life of the whole family. The Denari prosthesis is a viable treatment option for children with this syndrome, as it accompanies the maxillary growth, restores the functions of the stomatognathic system, prevents deleterious oral habits and helps with phonetics. It is necessary for the dentist to be able to offer the best treatment for these patients, as the syndrome makes it difficult, but does not impede its execution.

Objective: to review the literature on rehabilitative possibilities for patients with dental erosion. Method: literature screening that followed the principles of the SANRA check list. The search was performed in the BVS (LILACS and BBO), Scielo, Cochrane Library and PubMed databases. English language studies and clinical case reports available in full were included. Articles published until February 2022 and without chronological restriction were searched. Results: among 44 articles identified, 10 were selected. Most studies (40%) were published in Brazil, followed by the United States (20%) and Italy (20%). The rehabilitation possibilities identified were the use of ceramic crowns, ceramic laminates and direct restoration with composite resin. Conclusion: it was possible to verify that the rehabilitation of dental elements with direct materials (composite resins) or indirect (ceramics or ceromers) has shown satisfactory results, according to the clinical cases investigated.

Oligodontia is a complex congenital deformity, as it includes the lack of permanent teeth, functional and psychosocial problems. The management of this deformity requires a multidisciplinary approach, that involves the work of an orthodontist, gnatologist, and a prosthetic specialist. In the following casereport the comprehensive treatment of the three siblings are presented having oligodontia and the oldest sister in addition has dental metal allergy as well. In all cases we used fixed dental prosthesis for the rehabilitation. In the treatment plan: facebow, arrow tracing, diagnostic wax-up, mock-up was used for the individual treatment, moreover, to treat the consecutive bite loss, bite elevation was necessary. As the oldest sister has metal allergy, in the treatment plan we used titanium framework. With the final restoration the functional, aesthetic, and psychosocial problems were solved, and the patients were satisfied with their new prosthetic appliances.

Objective: To investigate the incidence and risk factors for non-adaptation of the conventional mandibular complete denture (CMCD). Materials and methods: A total of 108 edentulous patients were rehabilitated with complete dentures (CDs) and followed up at 3- and 6-month intervals. Adaptation was confirmed based on chewing, phonetics, and comfortable swallowing with the CDs. The risk factors among sociodemographic and patient-centered factors were analyzed. Statistical analyses included the chi-square test and then a multivariate analysis. Results: After 3 months, 38.0% of patients showed non-adaptation to CMCDs. Non-adaptation was significantly associated with the absence of previous mandibular denture experience (p = 0.042), ulcerations after 15 days of rehabilitation (p < 0.001), and a reduced posterior mandibular ridge (p = 0.035). After 6 months, this incidence decreased to 14.1%. The factors associated with non-adaptation were ulcerative lesions after 15 (p < 0.001) and 30 (p < 0.001) days of the delivery of CDs and the non-regular use of mandibular CDs (p < 0.001). Conclusion: The incidence of non-adaptation was higher after 3 months, with reduction after 6 months. Sociodemographic variables did not influence the adaptation. After 3 months, the absence of previous experience, traumatic ulcers, and reduced mandibular ridges hindered the adaptation of patients to mandibular CDs. After 6 months, only the occurrence of ulcerative lesions and non-regular wear of dentures were risk factors for non-adaptation. Clinical relevance: A considerable number of patients have difficulties in adapting to the mandibular dentures. Identifying the factors of non-adaptation of the dentures will contribute to increasing the predictability of this critical adaptation period. [ABSTRACT FROM AUTHOR]

With the development of digital dentistry, it is being applied in various ways of dental treatment. This case report presents the definitive prosthesis designed in advance with a re-established vertical dimension and the digital technology, which determined the amount of tooth preparation, in order to preserve as much tooth structure as possible in a patient with pathological wear of the posterior teeth and loss of vertical dimension. For accurate tooth preparation, the guides of the occlusal and axial surfaces were digitally and additively manufactured. Then, aesthetics and anterior guidance were established at the provisional stage. The information of the provisional restoration was delivered to the definitive stage by double scanning. The digital technology, including the virtual planning and the guided tooth removal, produced the definitive restorations satisfactory to both the patient and clinician. [ABSTRACT FROM AUTHOR]

When planning oral rehabilitation for maxillary edentulous patients, fixed prosthetic restoration using implants, complete denture restoration or overdentures using implants can be considered as treatment methods. In the case of complete denture restoration, it does not require additional surgery and is relatively economical. In the case of implant-supported fixed prostheses, the functional part is generally superior to that of complete denture restoration, but there are cases in which implant placement is clinically difficult. Recently in consideration of the patient's needs and the condition of the remaining alveolar bone, after partial implant placement, a method of restoring with a removable partial denture using implant-supported surveyed crown is also being attempted. This case is a case of performing a removable partial denture restoration using implant-supported surveyed crown in the anterior maxilla, and showing satisfactory esthetic and functional results.

The evaluation of the oral health-related quality of life (OHRQoL) is important for clinical assessment and could be an indicator of the quality of the treatment received. Objective: To evaluate the OHRQoL in adults with removable prostheses in relation with patient characteristics such as age, sex, type and time of use of the prosthesis, previous experience and perception about the stability of the prosthesis. Materials and Methods: 217 patients from the Dental Clinic of the National University of San Marcos-Peru were evaluated after rehabilitation with a removable prosthesis. A structured questionnaire was applied by telephone interview. The evaluation of the OHRQoL was carried out using the General/Geriatric Oral Health Evaluation Index (GOHAI). For the statistical analysis, the Mann Whitney U test, the Kruskal-Wallis H test and the Spearman correlation were used. Results: The sample included 63 men (29%) and 154 women (71%) with an average age of 66.34. The average GOHAI score was 52.44+8.15. The GOHAI score was related to age (p=0.241), sex (p=0.110), type of prosthesis (p=0.069), previous experience (p=0.293), and perception of movement of the prosthesis (p

Background: Children with congenital heart disease (CHD) are at high risk of contracting oral diseases. The aim of this study is to investigate dental procedures to prevent the risk of infective endocarditis in children with CHD., Material and Methods: 146 patients aged 2-14 years, in need of prophylaxis before cardiovascular surgery and who had filled out anamnesis records, were considered. Dental caries in all the children with CHD was reported as the number of decayed, missing and filled teeth (DMFT)., Results: There was a significant strong positive relationship between the pre-oral rehabilitation DMF-T/dmf-t scores and the number of caries patients (r=0.95, p=0.01). There was no significant correlation between the pre-oral rehabilitation DMF-T/dmf-t scores and both tooth loss (r=0.14, p=0.09) and the number of restorations (r=0.11, p=0.17). In addition, there was no significant correlation between the post-oral rehabilitation DMF-T/dmf-t scores and the prevalence of dental caries. A positive and moderately strong correlation was found between the post-oral rehabilitation DMF-T/dmf-t scores and the number of missing teeth (r=0.56, p=0.01), while there was a positive and strong relationship between the post-treatment DMF-T/dmf-t scores and the number of fillings (r=0.62, p=0.01)., Conclusions: Extraction should be considered when providing oral rehabilitation, rather than endodontic and deep restorative treatments.

Introduction: Defects in the maxillary anterior teeth are delicate and difficult to solve because of the esthetic, functional, and psychological impairment that may arise if the rehabilitation treatment does not return the damaged tissues to the naturalness. Esthetic predictability and reduced surgical interventions are some great reasons to simplify dental treatments. During the presurgical evaluation, the clinician should review the implant esthetic risk profile, considering the patient's smile line, the esthetic demands, the hard and soft tissue thickness and width, and the gingival biotype. Thus, achieving long‐term esthetic results initiates with a detailed case planning before surgical intervention. Case Presentation: The present report described a complex esthetic clinical case involving teeth and dental implant related to a high smile line. The clinical case was solved through immediate implant placement and immediate loading using a personalized prosthetic abutment and finalized with the installation of metal‐free prosthetic restorations. Conclusion: The use of a personalized prosthetic abutment helped to achieve a better emergence of the prosthesis under the periodontal tissues. Although it was a challenging esthetic case, especially because of the high smile line, the result was a natural smile while the adjacent soft tissues maintained their esthetics and health.

Abstract To assess facial changes after oral rehabilitation with complete dentures (CDs) by 3D technology allows understanding the results of a treatment that changes facial proportions. Precise outcome parameters can improve decision making. Objective This descriptive observational research aimed to assess facial changes in completely edentulous patients after oral rehabilitation with a CD by a 3D stereophotogrammetry system. Methodology 30 edentulous patients (7 men and 23 women), aged 50 to 75, were analyzed with stereophotogrammetry at 28 previously determined anthropometric landmarks, at 2 different times: T1, before treatment, and T2, after inserting the CDs. Images were analyzed with a specific software for linear and angular measurements. The paired t-test was used to compare timestamps (α=0.05). Results Major changes were observed in 7 of the 13 linear measures and 7 of the 9 angular measures. The following linear measurements had an increase: Sn-Gn (lower third of the face), Ls-Li (height of the vermilion lip), and ChL-ChR (mouth width). Sn-Ls (nasal philtrum height) decreased. For angular measurements, Sn-St-Pg (lower facial convexity) angles increased, and the Prn-Sn-Ls (nasolabial angle) and GoR-Pg-GoL (mandible convexity) angles decreased. Conclusions Major facial changes in newly rehabilitated edentulous patients with CDs included an increase of the lower third of the face, of the vermilion lip, of mouth width, and of the lower facial convexity, and a decrease of the nasolabial angle and mandible convexity.

Palatally impacted canines are usually challenging to treat in terms of both biomechanics and possible side effects. Different therapeutic approaches have been reported with or without the use of temporary anchorage devices, including the canine-first approach. Two groups of patients with palatally impacted canines were compared, observing their canine movement measured on consecutive CBCTs after three months of treatment. In the control group, impacted canines were treated with direct anchorage on miniscrews, and in the test group with indirect anchorage using a miniscrew-supported transpalatal arch. The primary outcome was the canine movement speed; the secondary outcome was the change in the root length of adjacent teeth. The median monthly apex speed was 1.05 mm in the control group (IR [0.74, 1.64]) and 0.72 mm in the test group (IR [0.27, 1.30]). The median monthly cusp displacement was 1.89 mm in the control group (IR [1.04, 2.84]) and 1.08 mm in the test group (IR [0.81, 1.91]). Approximately 50% of teeth adjacent to an impacted canine underwent a negative root length change of less than 1 mm in the majority of cases, but no significant differences were found in root length changes between groups. No statistically significant differences in the reported speeds were found, and no miniscrew failures were observed in either group.

ABSTRACT The aim of the current study is to present a treatment approach in a case of severe early childhood caries (ECC). A 5-year-old girl was referred to the Pediatric Dentistry Division with multiple premature tooth loss, masticatory difficulties, prolonged breast-feeding, and low quality of life, who was diagnosed with severe ECC. A three-phased treatment plan was implemented: 1. Disease control – consisting of behavioral changes in oral hygiene habits, diet guidance, professional biofilm removal followed by fluoride application and temporary restorations; 2. Infection control – teeth extractions and pulpotomy; and 3. Functional rehabilitation – direct and semi-indirect resin restorations, a removable partial and total prostheses in the lower and upper jaws, respectively. In conclusion, the proposed multidisciplinary approach resulted in a positive impact on the patient’s nutrition and growth, speech production, communication, self-image, and social functioning leading to an improved quality of life.

Background: Tooth decay and periodontal disease are currently considered the main causes of tooth loss. Timely prosthetic rehabilitation is the ideal treatment for this problem, as it allows the restoration of lost functions. Objective: to characterize tooth loss in relation to the need for prosthetic treatment. Methods: descriptive, observational, cross-sectional study, carried out with all the patients who attended the El Carmen stomatological consultation, belonging to the Barrio Adentro Mission in the Barinas, Venezuela, from January to June 2018. The age, tooth loss, need for prosthetic treatment and type of prosthesis were analyzed. Results: female sex predominated, represented by 62.4%, and patients aged between 19 and 34 years old, with 48.7%. The loss of 7 and more teeth prevailed in the studied group. The 63.4% required prosthetic treatment, and partial rehabilitation was the most demanded. Conclusion: the conditions of oral health, specifically of tooth loss, in these Venezuelan patients, were characterized by the predominance of the female sex, as well as the youngest. A large number of participants were affected by the absence of seven and more teeth. The need for prosthetic treatment increased with age, with a greater demand for partial prostheses.

Objectives: The purpose of this study was to assess the effects of oral rehabilitation with complete dentures on bite force and electromyography of the suprahyoid and sternocleidomastoid muscles, and their correlation with occlusal vertical dimension (OVD). The research questions were "What are the effects of rehabilitation with complete dentures on bite force and electromyography of suprahyoid and sternocleidomastoid muscles, and how are they correlated with OVD?" Materials and methods: Patients who are wearers of unsatisfactory removable complete dentures were attended in three sessions (T0, T1, and T2). At T0, while the patients still wore the old dentures, they were submitted to bite force and surface electromyographic exams of the suprahyoid and sternocleidomastoid muscles. These exams were repeated, and the OVD was measured while the patients wore their old and new prostheses, 30 days after insertion of the new prosthesis (T1). The exams were repeated 100 days after the insertion of the new prosthesis (T2). The data were submitted to the Shapiro-Wilk normality test, analysis of variance (ANOVA), and Pearson correlation and linear regression, all with 5% significance. Results: Fifteen patients participated in the study. No statistically significant difference was observed for bite force or electromyography in T0, T1, or T2. However, the correlation and regression tests showed important interactions between the OVD and maximum voluntary occlusal bite force, as well as the OVD and electromyography during deglutition for the suprahyoid muscles. Conclusion: Rehabilitation did not impact bite force nor the activity of the assessed muscles (electromyography). On the other hand, OVD was shown to be an important factor for bite force, and deglutition of water after rehabilitation. Clinical relevance: This study shows what are the influences of rehabilitation on oral functions and reinforces the importance of corrected reestablishment of OVD because it has been found to be an important factor for bite force and electromyography during deglutition.

Background. Implant fractures can cause difficult problems for patients and dentists. This systematic review aimed to determine the influence of some implant parameters on the occurrence of their fracture and to determine the incidence of fractures reported in recent years. Methods. A search was conducted in Pubmed database, from which 12 studies published in the last 12 years were selected. Results. This review reported a 2% incidence of implant fracture. Most implants had been in function between 3 and 4 years until fracture. The studies did not provide necessary information to establish a relationship between the different parameters of implants and the incidence of fractures. Conclusion. Thus, the indication of type, diameter and length of an implant and the bone quality in the region receiving it should be studied and accurately examined for each individual case in order to avoid future failures.
