Rehabilitation of Surgically Reconstructed Partially Edentulous Mandible with Iliac Crest Graft After Ameloblastoma Resection with an Implant-Supported “Toronto Prosthesis”

Abstract

Ameloblastomas are locally invasive and benign odontogenic tumors with a high long-term recurrence rate. These lesions can cause serious anomalies in the facial area and alveolar bones, leading deformity and deterioration of functions. Wide local excision and reconstruction are required for the surgical treatment of these tumors. Aggressive resection effectively eliminates tumors; however, this approach may cause various problems that need reconstruction to restore the oral functions. In the present case report, the rehabilitation of surgically reconstructed partially edentulous mandible with iliac crest graft after ameloblastoma resection with an implant-supported “Toronto Prosthesis” is presented. In the surgical procedure, mandible was partially resected and simultaneous iliac bone graft was applied. Then, four dental implants were inserted into the reconstructed bone and implant-supported Toronto prosthesis was fabricated. The patient was satisfied with the final result of the treatment and recurrence was not observed during the 2-year clinical follow-up.
