The increasing use of cone beam computed tomography (CBCT) has led to a growing demand for DICOM software that enables the assessment and measurement of craniofacial structures. This study aimed to compare the airway volume and the minimum axial area in patients with cleft lip and palate using five different imaging software programs: Dolphin3D, InVivo Dental, ITK Snap, InVesalius, and NemoFAB. Initially, 100 CBCT scans were selected by an examiner, and their corresponding DICOM files were collected. The oropharyngeal segments were delineated following the manufacturer’s guidelines, using two different segmentation techniques: interactive and fixed threshold. The results were analyzed using the Friedman test and Wilcoxon post hoc test, with a 5% significance level for all statistical tests. The findings for both the minimum axial area and total volume revealed that the median values across the software groups were higher than expected, and significant differences were observed when comparing the groups (p < 0.001). All five software programs showed notable differences in their outputs. Specifically, a statistically significant difference in volume was found across all groups, except between InVivo and ITK-Snap. It is recommended that pre- and post-treatment comparisons be performed using the same software for consistency.

The treatment of atrophic jaw fracture is a challenge in maxillofacial surgery, due to both local and systemic factors of the affected patients. This article aims to report a case of bilateral atrophic fracture of the mandible treated with an intraoral approach through a thinner and locked 2.0 mm system mandibular plate and subsequent rehabilitation with an implant- supported prosthesis. This technique provided the patient with excellent masticatory, aesthetic, and functional recovery with less morbidity and faster recuperation.

Current treatment of odontogenic tumors (OT) ranges from simple enucleation by curettage or segmental resection. But the treatment does not stop here, we need to think about the rehabilitation of the patients. The Mandibular reconstruction can begin immediately postoperatively, but the delayed reconstruction can be the best option for treatment, because of the high risk of recurrence in some OT, but it is always a challenge. The aim of this study is to describe the approach of a case of mandibular odontogenic myxoma and your total rehabilitations. The segmental hemi-mandibulectomia was performed with an intraoral. After 2 year the iliac crest grafting to intraoral approach was done and after 6 months osseointegrated implants were put and the immediate load with hybrid prostheses was done. After 2 years of complete rehabilitation we can consider that this sequence looks like to be a good form to become social, psychological, esthetic and function in the patients.

A paradental cyst (PC) is an odontogenic lesion, which occurs near the cervical margin of the lateral surface of the root because of an inflammatory process. Generally, they are located on the buccal and distal faces of completely or partially erupted third molar teeth. The purpose of this article is to discuss two uncommon clinical cases of a bilateral PC associated with third molars. Its diagnosed from clinical and radiographic examinations. The diagnosis of a PC was established following the correlation of radiographic, surgical, and microscopic features.

Peripheral odontogenic fibroma (POF) is a rare lesion, the extraosseous counterpart of the odontogenic fibroma, an odontogenic tumor of ectomesenchymal origin. Clinically it resembles as the reactional processes and has slow growth. The purpose of the study is to present a clinical case of posterior maxillary POF mimicking inflammatory periodontal disease in a 42-year-old woman who, after complete surgical excision, is followed up every six months without recurrence of the lesion. POF is a lesion characterized by fibroblast proliferation containing portions of apparently inactive odontogenic epithelium. The surgical treatment, when well performed, presents a very favorable prognosis, with a rare chance of relapse. It is important to emphasize that all the gingival lesions should be submitted to the anatomopathological examination, and the radiographic examination of the region is fundamental to evaluate the extent of the lesion.

As fraturas mandibulares são altamente prevalentes nos traumatismos faciais e representam uma parte significativa dos atendimentos em Cirurgia e Traumatologia Bucomaxilofacial, especialmente no Brasil. Entre as regiões mais acometidas, o ângulo mandibular se destaca devido à sua propensão a complicações, como desalinhamento oclusal e dificuldades na consolidação óssea. O tratamento adequado é fundamental para minimizar sequelas funcionais e estéticas. O objetivo deste trabalho é relatar o caso de um paciente atendido na Santa Casa de Misericórdia de Araçatuba, que sofreu uma queda de bicicleta na semana anterior. Durante a avaliação clínica, foram observados edema endurecido na região submandibular direita, trismo, dor espontânea, crepitação mandibular e alteração oclusal. A tomografia computadorizada revelou uma fratura no ângulo mandibular direito. O paciente foi submetido a uma cirurgia para redução e fixação da fratura, realizada sob anestesia geral com a técnica de Champy, utilizando placas e parafusos do sistema 2.0. Além disso, um dreno de Penrose foi instalado para facilitar a drenagem pós-operatória e foi removido 24 horas depois, na alta hospitalar. O paciente recebeu alta com bom progresso e está sendo acompanhado ambulatorialmente. Este caso reforça a importância de um diagnóstico preciso e de intervenções terapêuticas adequadas, como a técnica de Champy, que se mostra eficaz na estabilização de fraturas mandibulares. O sucesso no manejo cirúrgico e na recuperação do paciente evidencia a relevância de abordagens individualizadas e criteriosas para minimizar complicações e garantir resultados funcionais e estéticos favoráveis.
