Reabilitação com prótese bucomaxilofacial: revisão de literatura / Rehabilitation with maxillofacial prosthetics

A odontologia reabilitadora tem como um dos seus ramos a especialidade de Prótese Bucomaxilofacial (PBMF), que visa restaurar ou substituir estruturas perdidas na região facial e no sistema estomatognático artificialmente, podendo ser ou não removidos pelo paciente. O presente trabalho objetiva revisar a leitura a respeito da reabilitação com PBMF e a sua aplicabilidade na clínica odontológica. Os indivíduos com alguma perda de estrutura na região de cabeça e pescoço, devido a traumas físicos e/ou químicos, defeitos congênitos, doenças autoimunes, neoplasias, infecções e parasitas, são pacientes para os quais há a indicação da reposição da parte ausente. As reconstruções podem ser perdas intraorais (área da maxila, mandíbula), extraorais (oculopalpebral, ocular, nasal, facial extensa e auricular) ou conjugadas. Esse é um trabalho multidisciplinar, com especialistas de áreas abrangentes e todos os especialistas trabalham de forma conjunta. Pode-se concluir que, embora seja uma das especialidades mais nobres da odontologia, ainda é muito desconhecida por parte dos estudantes e profissionais das áreas da saúde e são próteses absolutamente fundamentais para a reabilitação e qualidade de vida dos indivíduos que tem a necessidade do uso da prótese PBMF(AU)

Rehabilitating dentistry has as one of its branches the specialty of Oral and Maxillofacial Prosthesis (PBMF), which aims to restore or replace structures lost in the facial region and in the stomatognathic system artificially, which may or may not be removed by the patient. The present study aims to review the reading about rehabilitation with PBMF and its applicability in dental clinic. Individuals with some loss of structure in the head and neck region, due to physical and/or chemical trauma, birth defects, autoimmune diseases, neoplasms, infections and parasites, are patients in whom there is an indication for replacement of the absent part. Reconstructions can be intraoral (maximal area, mandible), extraoral (oculopalpebral, ocular, nasal, extensive facial and auricular) or conjugated losses. It is a multidisciplinary work, with specialists from the comprehensive areas and that all specialists work together. It can be concluded that although it is one of the noblest specialties of dentistry, it is still very unknown to students and health professionals, and they are absolutely fundamental prostheses for the rehabilitation and quality of life of individuals who need the use the PBMFprosthesis(AU)

Microvascular reconstructions in oral and maxillofacial surgery - Results of a survey among oral and maxillofacial surgeons in Germany, Austria, and Switzerland.

This study aimed to evaluate the use of microvascular free flaps (MFF) in oral and maxillofacial surgery (OMFS) in Germany, Austria, and Switzerland. A dynamic online questionnaire, using 42-46 questions, was sent to OMF surgeons based in hospitals in Germany, Austria, and Switzerland. The questionnaire was evaluated internally and externally. Aside from general information, data were collected on organizational aspects, approaches, MFF types and frequency, presurgical planning, intraoperative procedures, perioperative medications, flap monitoring, and patient management. Participants mostly performed 30-40 MFF each year (11/53). Most stated that the COVID-19 pandemic did influence MFF frequency (25/53) to varying extents. Radial forearm flap was most frequently used (37/53), followed by ALT (5/53), and fibula flap (5/53). Primary reconstruction was performed by most participants (35/48). Irradiated bony transplants were mostly used for implant placement after 12 months (23/48). Most participants (38/48) used reconstruction plates, followed by miniplates (36/48), PSI reconstruction (31/48), and PSI miniplates (10/48). Regarding the postoperative use of anticoagulants, low-molecular-weight (37/48) and unfractioned heparins (15/48) were widely used, most often for 3-7 days (26/48). Clinical evaluation was mostly preferred for flap monitoring (47/48), usually every 2 h (34/48), for at least 48 h (19/48). Strong heterogeneity in MFF reconstructions in OMFS was found, especially regarding the timepoints of reconstruction, types of osteosynthesis, and postoperative MFF management. These findings provide the chance to further compare the different treatment algorithms regarding relevant MFF aspects, such as postoperative management. This could create evidence-based treatment algorithms that will further improve the clinical outcomes in MFF reconstructions.

Practice patterns for initial management of oral leukoplakia amongst otolaryngologists and oral and maxillofacial surgeons.

OBJECTIVE: Oral leukoplakia is encountered frequently by otolaryngologists and oral and maxillofacial surgeons (OMFS). There are no consensus practice management guidelines for oral leukoplakia, resulting in heterogeneity in practice patterns. Characterization of practice patterns of providers who treat oral leukoplakia will be valuable to establish standards of care and future practice guidelines. MATERIAL AND METHODS: A survey was designed by the American Head and Neck Society Cancer Prevention Service collecting demographic and practice management data for treating oral leukoplakia. The survey was approved and distributed to members of the American Academy of Otolaryngology-Head and Neck Surgery and American Association of Oral and Maxillofacial Surgeons. Data analysis was performed using chi square and t-test where appropriate. RESULTS: 396 responses were collected: 83 OMFS, 81 head and neck fellowship-trained providers, and 232 otolaryngologists (non-head and neck fellowship-trained). Providers saw a wide volume of oral leukoplakia (23.0% >30 cases/year, 35.1% 11-30 cases/year, 41.2% 10 or less cases/year), with OMFS seeing more cases of oral leukoplakia. Factors most associated with consideration of initial biopsy included physical exam findings (94.4%), erythroplakia (82.3%), and smoking status (81.6%). The majority of respondents saw patients in follow-up within 1 month (24.8%) or within 1-3 months (46.5%). CONCLUSION: This survey identifies a range of practice patterns in initial management of oral leukoplakia, including indications for biopsy, and time for follow-up. This data provide insight into practice patterns amongst different groups of providers and can potentially lead to consensus guidelines for initial management of oral leukoplakia.

The Royal College of Surgeons of England, its Faculty of Dental Surgery and the origins of the Faculty of Dental Surgery.

The Royal College of Surgeons of England established a Faculty of Dental Surgery in 1947 as part of a wider reorganisation. Its Fellowship in Dental Surgery began at the same time and became a mark of recognition of high standing as part of training programmes for dental specialists. Although similar fellowships were later awarded by the surgical colleges in Edinburgh, Glasgow and Ireland, they are outside the scope of this article. Two questions are examined in this paper: when and why did they start?

How dentists and oral and maxillofacial surgeons deal with tooth extraction without a valid clinical indication.

OBJECTIVES: This study pertains to a secondary data analysis aimed at determining differences between oral and maxillofacial surgeons (OMFSs) and dentists handling dental extractions without an evident clinical indication. STUDY DESIGN: A survey of 18 questions was conducted among 256 OMFSs in the Netherlands and a random sample of 800 dentists Respondents could answer the questions in writing or online. The data was collected in the period from November 2019 to January 2020, during which two reminders were sent. Analysis of the data took place via descriptive statistics and Chi Square test. RESULTS: The response rate was 28.1% (n = 72) for OMFSs and 30.3% (n = 242) for dentists. In the past three years, 81.9% (n = 59) of the OMFSs and 68.0% (n = 164) of the dentists received a request for extraction without a clinical indication. The most common reasons were financial and severe dental fear (OMFSs: 64.9 and 50.9% vs dentists: 77.4 and 36.5%). Dentists were significantly more likely (75.6%, n = 114) than OMFS (60.7%, n = 34) to comply with their last extraction request without a clinical indication. Almost none of them regretted the extraction afterwards. As for the request itself, it was found that 17.5% (n = 10) of the OMFSs and 12.5% (n = 20) of the dentists did not check for patients' mental competency (p = 0.352). CONCLUSIONS: Given that most of the interviewed dental professionals complied with non-dental extraction requests when such extractions are ethically and legally precarious, recommendations for handling such requests are greatly needed.

Psychometric and Perceptometric Comparisons of the Perspectives of Orthodontists, Oral and Maxillofacial Surgeons, and Laypeople of Different Ages and Sexes towards Beauty of Female Jaw Angles (Intergonial Widths and Gonial Heights) on Frontal and Three-Quarter Views.

Objectives: The jaw angle plays an important role in facial beauty. Therefore, this study is aimed at comparatively determining the range of most attractive female intergonial widths and gonial heights on Perceptometric frontal-view and three-quarter-view images, from the perspective of orthodontists, oral maxillofacial (OMF) surgeons, and laypeople of different ages and sexes. Methods: This prospective multivariate Perceptometric study was performed on 4191 esthetic scores given by 127 individuals to 33 Perceptometric face images. Frontal view and three-quarter-view photographs of a normal young woman were modified by image editing software to create two Perceptometric sets, one for the 24 gradual changes of intergonial width on the frontal view, and the other for the 9 vertical changes of the jaw angle on the three-quarter view. An online questionnaire was designed including 24 frontal and 9 oblique view photographs. The questionnaires' internal consistencies were almost perfect. Enrolled were 127 raters, including 33 orthodontists, 32 OMF surgeons, and 62 laypeople. The esthetics of different images were compared across different professions, across different ages, and between the sexes using 2-way MANCOVA, ANCOVA, and Bonferroni; the zones of esthetic jaw angles and also the sensitivity of judges to Perceptometric anatomical changes were assessed using 2-way RM-ANCOVA and Bonferroni (α = 0.05, α = 0.0056, α = 0.0021, and ß = 0.05). Results: Orthodontists and surgeons gave the highest attractiveness scores to intergonial: interzygomatic ratio of 72.53%, while the best ratio was 74.45% for the laypeople. The range of beautiful intergonial is as follows: interzygomatic ratio was 72.53% to 86.03%. OMF surgeons and orthodontists gave the highest score to a gonial height of 4.5 mm above the mouth corner, while the laypeople gave the highest score to the gonial height of 4.5 mm below the mouth corner. The range of beautiful gonial height was from 4.5 mm above the mouth corner to 9 mm below the mouth corner. The education of observers may affect their perception of beauty; orthodontists tended differ from laypeople, overall and also specifically in the case of the highly attractive frontal images concerning the intergonial width changes. However, no such differences were detected between surgeons with orthodontists or laypeople. Although age did not affect the overall esthetic scores, it did affect the sensitivity of the judges to the anatomic changes. So did expertise, i.e., the expertise of judges affected their sensitivity to anatomical changes; orthodontists showed steeper slopes of esthetic preference alterations to anatomical changes, while laypeople had the gentlest slope of preference changes. Judges' sex did not affect either their overall esthetic preferences or their sensitivity to anatomic changes. Conclusion: Narrower female jaw angles and jaw angles that are vertically close to the level of the mouth corner may be unanimously more desirable. Thus, treatments aiming at widening the jaw angle of a woman or lowering it should be discouraged, at least in Persians. Orthodontists, but not surgeons, are more sensitive than laypeople to anatomic changes of the jaw angle. The judges' age can affect this perceptive sensitivity, but their sex cannot.

Opioid prescribing by oral and maxillofacial surgeons in the United States, 2016-2019.

OBJECTIVE: To describe opioid prescribing trends among oral and maxillofacial surgeons (OMFS). METHODS: Prescriptions by OMFS were identified from IQVIA Longitudinal Prescription Dataset, 2016-2019. OMFS-based, patient-based and population-based prescribing rates and changes in high-risk opioid prescribing were calculated annually. We used linear regression to describe trends. RESULTS: There were 13.9 million opioid prescriptions among 12.5 million patients (627 prescriptions/OMFS/year). Hydrocodone and oxycodone decreased by 20.9% and 39.2% (p < 0.05), while tramadol and codeine increased by 24.3% and 6.1% (p < 0.05), respectively. Opioid prescribing rates significantly decreased by 27 prescriptions/OMFS/year, 18.6 patients/OMFS/year and by 0.9 prescriptions/100,000 population/year (p < 0.05 for all). From 2016 to 2019, the proportion of opioids >3 days decreased by 54.2% (p < 0.05) and prescriptions ≥50 MME/day decreased by 66.3% (p < 0.05). Although the number of opioid prescriptions by OMFS decreased in most states, 12% of states experienced increases. CONCLUSION: Opioid prescribing, especially high-risk prescribing, by OMFS has decreased. However, targeted interventions are warranted in some areas.

Reliability and accuracy of the torque applied to osteosynthesis screws by maxillofacial surgeons and residents.

Applying the right torque to osteosynthesis screws is important for undisturbed bone healing. This study aimed to compare test-retest and intra-individual reliabilities of the torque applied to 1.5 mm and 2.0 mm osteosynthesis screws by residents and oral and maxillofacial surgeons (OMF-surgeons), to define the reference torque intervals, and to compare reference torque interval compliances. Five experienced OMF-surgeons and 20 residents, 5 of each 4 residency years, were included. Each participant inserted six 1.5 × 4 mm and six 2.0 × 6 mm screws into a preclinical model at two test moments 2 weeks apart (T1 and T2). Participants were blinded for the applied torque. Descriptive statistics, reference intervals, and intra-class correlation coefficients (ICC) were calculated. The OMF-surgeons complied more to the reference intervals (1.5 mm screws: 95% and 2.0 mm screws: 100%) than the residents (82% and 90%, respectively; P = 0.009 and P = 0.007) with the ICCs ranging between 0.85-0.95 and 0.45-0.97, respectively. The residents' accuracy and reliability were inadequate regarding the 1.5 mm screws but both measures improved at T2 for both screw types compared to T1, indicating a learning effect. Training residents and/or verifying the applied torque by experienced OMF-surgeons remains necessary to achieve high accuracy and reliability, particularly for 1.5 mm screws.

Awareness and Knowledge of Rare Diseases in German Dentists, Dental Specialists and Oral and Maxillofacial Surgeons: A Country-Wide Survey.

Background and objectives: Rare diseases affect an estimated four million patients in Germany. Approximately 15% of the approximately 6000 to 8000 rare diseases known globally show manifestations in the dental, oral and maxillofacial regions. The present survey evaluated the knowledge and management of rare diseases and their orofacial alterations by dentists, dental specialists and oral and maxillofacial surgeons and dentists working at university hospitals for dentistry and/or oral and maxillofacial surgery. Materials and Methods: The study was designed as an anonymous cross-sectional study. Two anonymous online surveys were performed in all dentists in Germany using the open-source survey software limesurvey. The study cohorts were divided into dentists, dental specialists and oral and maxillofacial surgeons in practice, and dentists who worked in university dental and oral and maxillofacial surgery centers. The survey was performed between 1 October 2020 and 31 March 2021. Results: A total of 309 dentists and oral and maxillofacial surgeons in private practice and 18 dentists or oral and maxillofacial surgeons working at universities participated. A total of 209 (86.7%) study participants working in private practice indicated that the topic of rare diseases should be considered clinically relevant. University participants indicated that there was a lecture on rare diseases in only 7 (63.6%) cases. Only 2 (13.3%) participants reported active research on the topic in their department. Conclusions: The current knowledge on rare diseases is inadequate in suitable screening and therapy. Most of the participants believed that knowledge of rare diseases was very important for daily dental practice. The self-estimations showed that all of the participants estimated their knowledge as very good or inadequate, with a tendency in the direction of inadequate knowledge.

Facial Trauma Call Reimbursement Patterns Among American Society of Maxillofacial Surgery Members.

Facial trauma accounts for over 3 million emergency room encounters each year in the United States and places significant financial burden on the health care system and surgeons. However, data on facial trauma call practices among plastic surgeons are lacking. We surveyed members of the American Society of Maxillofacial Surgeons (ASMS) regarding their experience with facial trauma call. A 27-question online survey was distributed through e-mail to ASMS members. Forty-five ASMS members completed the survey, of whom 64% were required to take facial trauma call and 44% were compensated for call. Respondents in the North-East were less likely [odds ratio (OR): 0.234, confidence interval (CI), 0.054-1.015; P =0.052] to be compensated for taking call, whereas those who worked at level 1 trauma centers were more likely odds ratio: 5.42, CI, 0.892-32.89; P =0.066) to be compensated. Surgeons required to take facial trauma call were 4.646 (CI, 1.203-17.944; P =0.026) times more likely to take call ≥5 days per month. These results highlight a relatively low proportion of plastic surgeons receiving additional compensation for facial trauma call while work at a level 1 trauma center was associated with higher likelihood of compensation. Surgeons in the Northeast may be compensated less frequently than other regions. Plastic surgeons should be aware of these trends, as they decide how to incorporate facial trauma call into their practice.

Clinical Anatomy Research Association in Oral and Maxillofacial Surgery.

ABSTRACT: Sufficient knowledge of anatomy is critical for oral and maxillofacial surgeons to provide the best treatment to their patients. The authors have recently established the "Clinical Anatomy Research Association in Oral and Maxillofacial Surgery." There is no doubt as to the benefits of collaboration between oral and maxillofacial surgeons/radiologists and anatomists. In this article, we share what was accomplished at the first annual online conference and discuss our mission for the future.
