RESUMODescrito primariamente por HOPE em 1840, o termo miíase é utilizado para denominar a invasão de ovos ou larvas de moscas da ordem díptera nos tecidos humanos ou de animais vertebrados. Associada a higiene pública e pessoal inadequada, esta condição pode acometer qualquer órgão ou tecido que sejam acessíveis para oviposição. Relatado pela primeira vez na cavidade oral em 1909 por Laurence, este é um acontecimento raro que ocorre com maior frequência na região anterior da maxila e está associado a presença de lesões, bolsas periodontais, halitose grave, respiração bucal, ausência de selamento labial, trauma supurativo e má higiene oral, sendo ainda classificado como grupo de risco aqueles indivíduos que sejam incapazes de zelar pela própria saúde. O tratamento da miíase não é protocolado, portanto são adotadas diversas terapias de acordo com as condutas dos profissionais, porém é consenso entre os autores que a abordagem inicial deve ser realizada por meio da remoção mecânica das larvas. Podem ser adotadas terapias medicamentosas e clinicas que tornem o meio anóxico e antiparasitário. O objetivo deste artigo é relatar um caso de infestação por miíase em cavidade oral em um paciente portador de paralisia cerebral decorrente de uma meningite.
Nasal bone fractures are very common, and their approach should be immediate to better repair the defects. This is not always possible, which makes the surgical procedure more complex, often going from a simpler fracture reduction to a nose reconstruction. There are several materials and techniques to perform this type of procedure, among them the implant made from polymethyl methacrylate (PMMA). This study aimed to report a case of nasal dorsum reconstruction using a customized in situ molded PMMA prosthesis. A 24-year-old male patient searched for a public hospital with sequelae of fracture in his nasal bones, resulting from a mule kick twenty years ago, with aesthetic complaints. On physical examination, a significant loss of projection of the nasal dorsum was observed with local cicatricial fibrosis. To correct the defect, a prothesis constructed from PMMA was molded and installed, fixed with plates and screws. The patient has been under follow-up for one year with an acceptable result. Although it is not the first option in many cases for nasal dorsum reconstruction, PMMA can be used to repair existing sequelae areas, achieving satisfactory aesthetic results.
<p class="Body"><strong>Aim:</strong> to report on the applicability of biomodels obtained from computerized tomography (CT) images through the technique of stereolithography (SLA) and three-dimensional printing (3DP), in the clinical case reports of patients who underwent surgeries involving dentoskeletal deformity, oral pathology and oral and maxillofacial trauma. <strong>Metodology: </strong> Clinical case 01 deals with fractures in the orbital and zygomatic arch region that required reconstruction and correction of diplopia, by means of CT images, using the technique of three-dimensional printing through SLA, generating a mirrored biomodel for surgical planning and the making of customized prostheses. In clinical case 02, by means of CT images, a biomodel utilizing the 3DP technique showed the total area invaded by invasive ameloblastoma, making it possible to plan the osteotomy with maximum preservation of the adjacent tissue and prior modeling of the plate. In clinical case 03, rapid prototyping technology (RP) was used to make customized prostheses for temporomandibular articulation, with the goal of correcting a serious idiopathic pathology provoking the resorption of the right and left condyles. <strong>Discussion: </strong>Complex cases require the team to have recourse to technology for the implementation of the procedures, in order to offer excellent quality treatment to the patient, in addition to facilitating surgical planning and permitting the construction of customized prostheses. <strong>Conclusion:</strong> that rapid prototyping for the acquisition of biomodels is an important auxiliary tool for the surgical team. </p>
