Outcome of partial mandibular reconstruction with fibula grafts and implant-supported prostheses.

This study sought to evaluate the outcome of patients treated with fibula grafts for partial mandibular reconstruction and implant-supported prosthesis at a Danish university hospital. Patient inclusion criteria were: partial mandibular resection, reconstruction with a fibula graft, and treatment during the period 1998-2011. Patients with incomplete medical records were excluded. Thirty-six patients were included, of whom 16 were treated with an implant-supported prosthesis. Relevant presurgical, intraoperative, and postoperative parameters were registered. The fibula graft survival rate at the last follow-up (mean follow-up 22 months, range 0-89 months) was 97%. Half of the patients experienced non-severe complications such as loosening of osteosynthesis material, fistulae, and graft exposure. One of 37 fibula grafts in the 36 patients was removed due to infection. The implant survival rate was 96%; three of 67 implants were lost due to infection. Eight implants were not included in the prosthetic rehabilitation. Fibula graft surgery for mandibular reconstruction was found to be a reliable treatment modality with a high survival rate. Rehabilitation with implant-supported prostheses was characterized by high survival rates and few complications. The results obtained are comparable to those of previous studies.
