title: Mandibular reconstruction using iliac bone and great auricular nerve grafts and oral rehabilitation using osseointegrated implants in a patient with a large ossifying fibroma: a 10-year follow-up study.
abstract: Ossifying fibromas are bone-related benign neoplasms that are characterized by well-demarcated lesions composed of fibrocellular tissue and mineralized material with varying appearances. Although small lesions are asymptomatic, they may cause enlargement of the affected jaw and rarely require reconstructive or restorative treatments for aesthetic and functional problems. In this study, we report a 35-year-old woman who underwent multidisciplinary treatment for a large ossifying fibroma of the mandible. A segmental mandibular resection was performed, and immediate reconstruction was performed using iliac bone and great auricular nerve grafts. After consolidation of the grafted bone, oral rehabilitation was fulfilled using osseointegrated implants and a fixed prosthesis. There was no evidence of recurrence ten years after the resection of the tumor. The range of mouth opening and motion of the temporomandibular joint provided a functional mandible. The neurosensory examination revealed the recovery of sensibility of the mental region and pulpal sensitivity of the teeth. The prosthesis was stable, and no clinical or radiographic signs of implant failure were observed. Our results demonstrate that the proper combination of reconstructive and restorative treatments could result in appropriate aesthetic and functional outcomes for a period of ten years.
