Abstract

A 22-year-old female patient attended the service of Oral Maxillofacial Surgery of UFRN, with anatomopathologic report of solid ameloblastoma. On physical examination, the patient presented discrete volume increase in the posterior region of right mandible, satisfactory buccal opening, and preserved inferior alveolar nerve integrity. At tomographic examination, osteolytic lesion can be observed, located in branch, angle, and right mandibular body, approximately 6 cm in its largest diameter. Mandibular reconstruction with unilateral mandibular prosthesis was planned, but it had to be authorized. She underwent a first surgical procedure for resection of the lesion and installation of reconstruction plaque of 2.4-mm system. After 6 months, the plaque was removed from the reconstruction and disarticulation of proximal segment for the installation of a prototyped mandibular prosthesis. The patient evolved in the postoperative period of 3 years presenting mandibular contour, mandibular movements, and preserved facial mime, including a total social reinsertion.
