Mandibular reconstruction with the use of heat-treated bone is reported. The patient was a 35-yearold woman with odontogenic myxoma of the mandible. The tumor was distributed throughout the mandibular body, and a mandibulectomy was carried out from 36 to 46. The resected bone segment was treated in physiological saline solution at 80℃ for 30 minutes by pasteurism after removing the alveolar process and intraosseous tumor tissue. The marrow space of the treated bone was filled with bone fragments harvested from the ileum, and the bone was then replanted into the defect of the mandible. The postoperative course has been uneventful for 3 years, with neither recurrence of the tumor nor resorption of the bone grafts.
