RESUMO

The technique of sagittal split osteotomy of the mandibular ramus is an established technique that has been evolving over the years, with significant improvements regarding stability, better bone contact between the segments, and possibilities of osteosynthesis. However, paresthesia is common in the postoperatory, sometimes permanent, and undesirable fractures in the subcondylar region can occur leading to longer operative time and extraoral scars. The short lingual split technique is an easy technique that simplifies the horizontal osteotomy of the ramus and decreases the risk of undesirable fractures with a neurosensitive recovery of patients in a much shorter time because of minor trauma and nerve manipulation during the execution.

RESUMO

New possibilities such as Surgery-first and Minimal Presurgical Orthodontics have become extra alternatives for patients, orthodontists, and oral and maxillofacial surgeons, with immediate facial improvements, reduced preparation time, and shorter treatment time. The purpose of this case report was to demonstrate the retreatment of a female patient, dissatisfied with the instability of the compensatory orthodontic treatment, chin deviation, and forward inclination of the maxillary incisors, which was successfully treated with Minimal Presurgical Orthodontic approach associated with customized lingual brackets and virtual planning on the open-source Blender 3D software, where the post-surgical maxillary lingual brackets were also designed. Orthodontic preparation was performed in 5 months. After surgery, orthodontic treatment was finished with the aid of mini-implants and miniplates. The total treatment time was 18 months. Great facial and occlusal results were obtained and the patient was satisfied. Overall, all treatment steps were performed following a digital workflow and open-source software. It is possible to conclude that Minimal Presurgical Orthodontic Preparation was an excellent alternative for the retreatment of this patient with mandibular asymmetry and increased treatment expectations. Additionally, the surgical planning and design of lingual braces with open-source software can be considered useful and low-cost alternatives for orthodontists.

RESUMO

ABSTRACT Osteochondroma is one of the most common benign bone tumours. However, it a rare in the mandibular condyle. Depending on the symptoms and duration of the osteochondroma, the management ranges from excision of the tumor alone to condylectomy along with tumor excision. This paper presents a case of Osteochondroma after surgical treatment affecting the mandible of a 39-year-old man and highlights the diagnosis, surgical procedures and 3-year follow-up period. At the clinical examination, the patient presented severe mandibular lateral deviation to the right, left side disocclusion with a slight oral opening limitation, dental abrasion compatible with bruxism and class III. After 3-year follow-up 3 years later revealed that the surgical management posed was successful for Osteochondroma and the patient is currently under regular review.


RESUMO Osteocondroma é um dos tumores ósseos mais comuns, mas raramente acomete o côndilo mandibular. Dependendo dos sintomas e duração do Osteocondroma o manejo da lesão pode variar desde a excisão do tumor até a realização da condilectomia com a remoção do tumor. O objetivo deste trabalho é relatar um caso clínico de Osteocondroma acometendo o côndilo da mandíbula em um paciente de 39 anos de idade, ressaltando as etapas para a realização do diagnóstico, procedimentos cirúrgicos e follow-up de 3 anos. Ao exame clínico observou-se severo desvio mandibular para o lado direito, desoclusão do lado esquerdo, abertura de boca reduzida, abrasão dentária compatível com bruxismo e classe III. Após a realização de tratamento cirúrgico e o período de acompanhamento de 3 anos foi possível observar a resolução do caso em imagens de tomografia computadorizada de feixe cônico. Conclusão: Pode-se concluir que a terapia proposta resultou em sucesso e o paciente continua em acompanhamento periódico.

RESUMO

O fibro-odontoma ameloblástico é um tumor benigno raro, classificado como tumor odontogênico misto. Ocorre principalmente em crianças na primeira década de vida, sendo 65% dos casos em mandíbula. O exame radiográfico é bastante característico, apresentando imagem radiolúcida em "bolha de sabão" com tecido fortemente radiopaco associado. Apesar da aparente agressividade da lesão relatada nesse caso clínico de grandes proporções, o tratamento proposto foi conservador, via acesso extra-oral, mantendo-se a integridade do nervo alveolar inferior, com preservação da base da mandíbula e dentes adjacentes e mostrando excelente neoformação óssea.


The ameloblastic fibro-odontoma is a rare benign tumor, classified as a mixed odontogenic tumor. It usually occurs in children in the first decade of life, and in 65% of the cases it is within the mandible. The radiographic exam is fairly characteristic and presents a radiolucent "soup bobble" image associated to an intense radiopaque tissue. Despite of the aggressive appearance of the lesion reported, the proposed treatment was conservative, extra-orally accessed, keeping the alveolar inferior nerve intact, preserving the mandibular base and the adjacent teeth and showing an excellent new bone formation.
