Introduction: Exostoses and mandibular torus have uncertain and multi-factorial etiology, but it is believed that environmental and genetic factors are related. They are more common in the male gender, prevailing from 0.09 to 19% in the former and from 5 to 40% in the case of mandibular torus. Objective: The present study aimed to investigate a clinical case of surgical removal of extensive exostosis of maxilla and mandibular torus. Method: Patient attended the CTBMF with complaint of impossibility of prosthetic rehabilitation. After the clinical examination, a maxillary edentulous arch with large lobulated-looking bone volume was observed. In the mandibular arch, bone protuberance was observed along the lingual surface in the premolar region and surgical removal of the maxillary, and mandible ex- ostoses under local anesthesia was indicated. There were no intercurrences in the postoperative period. Histopathological examination revealed fragments of lamellar bone tissue, with predominantly compact areas in the peripheral regions. Results: The inflammation was minimal and the patient reported little postoperative discomfort. Conclusion: The exostosis are common physiological changes that make prosthetic rehabilitation impossible, and the maxillary complex surgery is indicated to rehabilitation.
