RESUMO

Aim: The aim of the present study was to evaluate the microbial contamination in internal and external walls of cone morse implant walls. Methods: Eleven patients with edentulous mandibular posterior area were selected to received dental implants, divided into groups: submerged (S), non-submerged (NS), and immediately loaded (IL). Microbiological evaluations (microorganisms' number, aerobic and anaerobic colony forming units (CFU) number and microorganisms' qualification) were divided into internal and external collection of the implant walls, at different stages: T0 (surgical procedure), T2 (suture removal), T4 (reopening S group), T6 (suture removal S group), and T8 (abutment placement in S and NS). All data were submitted to statistical analyses, with confidence level of 0.05. Results: There was difference in number of microorganisms observed over time within the same group (p < 0.05). A difference was observed in CFU when evaluated within the same group over time (p < 0.05), except for the IL group. In internal collection, a predominance of non-formation of microorganisms was observed at T0 in all groups, while formation of Gram-positive Diplococci and Gram-positive Bacilli was observed at T8 (p>0.05). In external collection, an increase in number of microorganisms was observed at T0. Conclusion: There was no difference in microbial contamination among the evaluated groups. The microorganism's colonization changed over time

RESUMO

Introduction: One of the challenges of maxillofacial surgery is the rehabilitation of patients with severe bone loss, using implant-supported prostheses. This challenge is based on the small remaining bone structure, and on the need to reconstruct the structure for the rehabilitation with autogenous or exogenous grafts. Case report: We report the case of a patient with severe maxillary atrophy, where a skullcap graft was performed associated with implant placement and prosthetic completion 14 months after the start of treatment. Final considerations: We demonstrate clinical safety for the use of extraoral grafts without complications, representing a good alternative treatment for this group of patients.


Introdução: um dos desafios da cirurgia bucomaxilofacial é a reabilitação de pacientes com perda óssea severa, utilizando próteses implantossuportadas. Este desafio baseia-se na pequena estrutura óssea remanescente e na necessidade de reconstrução da estrutura para a reabilitação com enxertos autógenos ou exógenos. Relato de caso: Relatamos o caso de um paciente com atrofia maxilar grave, onde foi realizado enxerto de calota craniana associado à instalação de implante, com finalização protética 14 meses após o início do tratamento. Consideracoes finais: Demonstramos segurança clínica para o uso de enxertos extrabucais sem complicações, representando uma boa alternativa de tratamento para este grupo de pacientes.

RESUMO

Aim: This study aimed to systematically review existing literature regarding the association between dental procedures­such as tooth extractions and periodontal therapy­and occurrence of medication-related osteonecrosis of the jaw (MRONJ) in individuals using bone-modifying drugs. Methods: Search strategies were performed in PubMed, Scopus, Web of Science and Cochrane Library for a timeframe ending in December 2021. Study selection, data extraction and risk of bias were analyzed independently by two researchers. Three meta-analyses were performed, estimating the crude risk ratio (RR), the adjusted odds ratio (OR) and the adjusted hazard ratio (HR) for the association between tooth extraction and MRONJ. Results: Of the 1,654 studies initially retrieved, 17 were ultimately included. The majority of patients with MRONJ in these studies were female, with a mean age of 64 years. Zoledronic acid was the most commonly used drug among patients with MRONJ, and cancer was the most frequent underlying health condition. Regarding the performed meta-analyses, crude and adjusted analyses demonstrated that tooth extraction increased the risk for MRONJ by 4.28 (95% confidence interval [95%CI]: 1.73­10.58), the OR for MRONJ by 26.94 (95%CI: 4.17­174.17), and the HR for MRONJ by 9.96 (95%CI: 4.04­24.55). Conclusion: It was concluded that performing dental procedures, especially tooth extraction, in patients using bone-modifying drugs increased the risk of MRONJ occurrence and, therefore, should be avoided. Further studies, using adjusted data, are warranted

RESUMO

Aim: to evaluate the surgical effects of two rehabilitation protocols on dental arch occlusion of 5-year-old children with or without cleft lip and palate. Methods: this is a retrospective longitudinal study the sample comprised 45 digitized dental casts divided into followed groups: Group 1 (G1) ­ children who underwent to cheiloplasty (Millard technique) at 3 months and to one-stage palatoplasty (von Langenbeck technique) at 12 months; Group 2 (G2) ­ children who underwent to cheiloplasty (Millard technique) and two-stage palatoplasty (Hans Pichler technique for hard palate closure) at 3 months and at 12 months to soft palate closure (Sommerlad technique); and Group 3 (G3) ­ children without craniofacial anomalies. Linear measurements, area, and occlusion were evaluated by stereophotogrammetry software. Shapiro-Wilk test was used to verify normality. ANOVA followed by posthoc Tukey test and Kruskal-Wallis followed by posthoc Dunn tests were used to compared groups. Results: For the measures intercanine distance (C-C'), anterior length of dental arch (I-CC'), and total length of the dental arch (I­MM'), there were statistical differences between G1x G3 and G2xG3, the mean was smaller for G1 and G2. No statistically significant differences occurred in the intermolar distance and in the dental arch area among groups. The occlusion analysis revealed significant difference in the comparison of the three groups (p=0.0004). Conclusion: The surgical effects of two rehabilitation protocols affected the occlusion and the development of the anterior region of the maxilla of children with oral clefts when compared to children without oral clefts.

RESUMO

In recent years, with the rapid development of digital technology, the application of oral virtual patients in prosthodontics, orthodontics, oral and maxillofacial surgery, and other disciplines has gradually increased. Although the focus on oral virtual patients varies in different disciplines, the application of oral virtual patients in assisting the prediction of treatment effects and the formulation of treatment plans will have good prospects. The construction accuracy and presentation effects of oral virtual patients can be influenced by the source of three-dimensional (3D) image, and methods of registration. Based on the studies and clinical experiences of our team, researches of other teams, the source of 3D images, the construction methods, and the clinical applications of virtual patients in prosthodontics will be presented, so as to provide a reference for normalized application and development of oral virtual patients and to offer a future development direction of oral virtual patients.

RESUMO

Inappropriate antibiotic prescriptions contributed to a global issue of antimicrobial resistance. This study aimed to assess the prevalence of bacterial pathogens and antimicrobial resistance isolated from maxillofacial infections (MIs). Two hundred and twenty-two patients with different MIs were included in this study. Swab samples were taken from the site of infections. Samples were cultured, and isolated bacteria were identified using various biochemical tests. Antimicrobial resistance patterns of isolates were assessed by the disk diffusion method. The mean age of the patients was 50.8 years. The male-to-female ratio was 127/95 (P<0.05). Smoking and alcohol consumption were found in 60.36% and 37.38% of patients, respectively. Most patients had a ≤1-week infection duration (P<0.05). Abscess lesion was the most predominant infection type (P<0.05). The prevalence of aerobic bacteria among abscess, pus localization, and deep facial infections was 59.33%, 64.28%, and 46.66%, respectively. The prevalence of anaerobic bacteria among abscess, pus localization, and deep facial infections was 40.66%, 23.80%, and 53.33%, respectively. Staphylococcus aureus (10.36%) and Prevotella buccalis (8.55%) had the uppermost distribution amongst all examined samples. Isolated bacteria exhibited the uppermost resistance rate toward penicillin (65.76%), tetracycline (61.26%), gentamicin (58.10%), and ampicillin (57.65%) antimicrobials. The lowest resistance rate was obtained for linezolid (25.67%), ceftriaxone (31.08%), and azithromycin (31.08%) antimicrobials. Linezolid, ceftriaxone, and azithromycin had effective antimicrobial activities toward bacteria isolated from MIs. Therefore, cautious antibiotic prescription might decrease the prevalence of antimicrobial resistance in dental and maxillofacial infections.

RESUMO

The Oral and Maxillofacial Surgery (OMS) Department at Waikato District Health Board (WDHB) is the only current OMS unit within New Zealand to reconstruct oral cavity defects with microvascular free flaps. The primary objective of the study was to retrospectively analyse the demographics, outcomes and complications of free flap surgery patients at WDHB.An OMS reconstruction database was developed and data collected retrospectively. 75 free flaps were performed on 74 patients between 2012 and 2020. There were 34 females and 40 males, with a mean and median age of 62 and 64 respectively. The tongue was the most common site of resection, and squamous cell carcinoma was the most frequent diagnosis. The radial forearm free flap was used most often followed by the fibula and anterolateral thigh flaps. The Clavien-Dindo classification was used to classify complications, with 10 patients having "major" complications and 34 patients having "minor" complications. Flap success rate was 98.7%, which meets internationally accepted standards of care.

RESUMO

Platelet-rich fibrin (PRF), a second-generation platelet concentrate, has been widely recognized in numerous studies for its performance of wound healing and regeneration in dentistry. However, bibliometric analysis of PRF in dentistry is still scarce. Thus, this study aimed to conduct and delineate a bibliometric analysis of the application of PRF and its changing trend in dentistry. All papers concerning PRF up to 30 June 2022 were included in the literature search from the Web of Science Core Collection database. These data were then entered into Microsoft Excel, analyzed by the SAS statistical software, and visualized by the VOSviewer software. A total of 562 articles were retrieved following the exclusive criteria. The results demonstrated that the trend of annual publication increased continually (p for trend < 0.01), more notably in the last five years. The majority of the articles were original (58.01%), followed by reviews (17.08%), and case reports (10.14%). The three major study designs were clinical studies (20.11%), randomized controlled trials (17.62%), and review/meta-analysis (17.08%). PRF was most frequently employed in oral surgery (31.14%), periodontal regeneration (22.42%), and implant therapy (18.68%). Turkey (16.19%), India (12.28%) and China (7.12%) were the top 3 countries publishing PRF studies. By comparing the total number of publications, total citation counts and varying counting methods, a combination of numerous counting methods was suggested for use since each counting method yields different results. Taken together, we hope with these informative findings, researchers could focus on the future direction or advancement in PRF, laying a foundation for evidence-based dentistry.

RESUMO

Introdução. Decorrente do trauma local, durante a exodontia, ou pela falta de estímulos mastigatórios, a ausência dentária promove respostas biológicas que desencadeiam um processo de reabsorção óssea. A preservação óssea alveolar propõe minimizar a reabsorção óssea alveolar, promovendo maior biodisponibilidade óssea para a reabilitação por implantes dentários. Os implantes dentários são uma modalidade terapêutica eficaz para a reabilitação de ausências dentárias. Objetivo. relatar um caso de reabilitação por implante em alvéolo cicatrizado, após preservação alveolar. Relato de caso. Paciente A.L.L., sexo masculino, 23 anos, compareceu à clínica odontológica da UNIBRA. Ao exame físico observou-se ampla destruição coronária do elemento 25 e, ao exame radiográfico notou-se tratamento endodôntico. O tratamento proposto foi a exodontia minimamente traumática, preservação alveolar com matriz de colágeno e instalação de implante dentário em alvéolo cicatrizado. Discussão. Em desdentados, a falta de estímulos mastigatórios, promove um desequilíbrio no turnover ósseo, desencadeando um processo de reabsorção. A preservação alveolar por matriz de colágeno visa minimizar a reabsorção e fornecer maior biodisponibilidade óssea para a reabilitação por implantes. Conclusão. A preservação alveolar com a matriz de colágeno cumpriu com seu objetivo e, a reabilitação por implante dentário em alvéolo cicatrizado é uma modalidade eficaz na reabilitação de pacientes desdentados...

Introduction. Due to local trauma, during tooth extraction, or the lack of masticatory stimuli, the absence of teeth promotes biological responses that trigger a process of bone resorption. Alveolar bone promotion minimizes alveolar bone resorption, promoting high bone bioavailability for rehabilitation with dental implants. Dental implants are a treatment modality to edentulous. Objective. Report a case of implant rehabilitation in a healed socket after alveolar preservation. Case report. Patient A.L.L., male, 23 years old, attended the UNIBRA dental clinic. On physical examination, a wide coronary destruction of element 25 was observed and, on radiographic examination, endodontic treatment was noted. The proposed treatment was a minimally traumatic tooth extraction, alveolar preservation with collagen matrix and implant placement in healed sockets. Discussion. In edentulous patients, the lack of masticatory stimuli promotes an imbalance in bone turnover, triggering a resorption process. Alveolar preservation by collagen matrix aims to minimize resorption and provide greater bone bioavailability for implant rehabilitation. Conclusion. Alveolar preservation with collagen matrix fulfilled its objective, and rehabilitation by dental implant in a healed socket is an effective modality in the rehabilitation of edentulous patients...

RESUMO

Diabetes mellitus (DM) is thought to be associated with poor outcomes in cervicofacial infections (CFI), yet little is known about the prevalence of DM in these cases. Stress hyperglycaemia (SHG), a normal physiological response to inflammation, is distinct from DM, though they overlap and may be conflated. We aimed to establish the prevalence of DM and SHG in CFI, and to determine the effect of each on severity of disease and outcome measures. The Maxillofacial Surgery Trainee Research Collaborative (MTReC) carried out an audit of all patients with CFI admitted to 25 hospitals between May and October 2017. To the best of our knowledge this created the largest prospective database on CFI, with information collected on presentation, source of infection, biological data, and outcomes. We recorded 1002 admissions, of which 78 (7.8%) had DM. Random blood glucose was measured on admission in 401 patients (40%), of which 45 (11%) displayed SHG. Patients diagnosed with DM were more likely to have infections arising from a salivary source (13% vs 4%, p<0.00), more returns to theatre (9% vs 2%, p<0.00), and a longer hospital stay (median (range) 2 (0-34) vs 1 (0-139) day, p=0.01) than non-DM patients. In contrast, patients with SHG had more severe disease (multiple fascial spaces involved in 59% vs 19%, p=0.01, and systemic inflammatory response syndrome present in 66% vs 45% p=0.03), but did not have significantly more returns to theatre (2% vs 3%, p=0.91) or longer stays in hospital (median (range) 1 (0-63) vs 1 (0-6), p=0.55) than normoglycaemic patients. The prevalence of DM in our cohort was only marginally higher than in the general population, despite previous retrospective case reviews suggesting a significantly higher prevalence. SHG was not associated with poor outcomes in our cohort, but is likely to be associated with a small increased risk of subsequent diagnosis of DM, which can be quantified using a calculator tool. On discharge, it is important to give appropriate advice about diet, lifestyle, exercise, and weight loss to all patients with CFI.

RESUMO

As life expectancy and the number of people living with chronic illness increases, the medical complexity of patients requiring oral surgery will also increase. This and the continuously evolving range of medical treatments used to manage their conditions will increasingly challenge dentists in both primary and secondary care to avoid complications and treat this patient group safely.This paper will describe the importance of careful treatment planning including consideration of the timing and location in which oral surgery is undertaken for medically complex patients. The risk of acute medical events, bleeding, infection, and impaired healing which may complicate oral surgical procedures in this group of patients is discussed and the role in their care played by general dental practitioners explored.

RESUMO

Reconstruction of defects in the maxillofacial region following traumatic injuries, craniofacial deformities, defects from tumor removal, or infections in the maxillofacial area represents a major challenge for surgeons. Various materials have been studied for the reconstruction of defects in the maxillofacial area. Biodegradable metals have been widely researched due to their excellent biological properties. Magnesium (Mg) and Mg-based materials have been extensively studied for tissue regeneration procedures due to biodegradability, mechanical characteristics, osteogenic capacity, biocompatibility, and antibacterial properties. The aim of this review was to analyze and discuss the applications of Mg and Mg-based materials in reconstructive oral and maxillofacial surgery in the fields of guided bone regeneration, dental implantology, fixation of facial bone fractures and soft tissue regeneration.
