Implant-prosthetic rehabilitation after segmental mandibulectomy and bone grafting

A free vascularized fibula (6 cases) and iliac bone (11 cases) graft were used to reconstruct a mandibular discontinuity defect resulting from cancer surgery in 17 patients. Fifty-two osseointegrated DenTi implants were secondarily placed into the grafted bone, and all the patients underwent prosthetic rehabilitation. (DenTi is an endosseous dental implant system invented and manufactured by Denti-System Ltd., Szentes, Hungary.) To date, the maximum follow-up time after prosthetic treatment is 5 years, the minimum is 2 years. During this time, only one of the 52 inserted implants was lost, and that occurred a few days after insertion. Clinical signs of peri-implantitis were observed in only 2 of the fixed prosthetic restorations. Long-term maintenance is essential if such patients are to achieve successful prosthetic restorations and, thus, enhanced lives.
