Functional rehabilitation of the atrophic mandible and maxilla with fibula flaps and implant-supported prosthesis.
Historically, nonvascularized bone grafts have been the standard treatment for severe mandibular and maxillary atrophy, followed by immediate or delayed implant placement. Extreme atrophy is an unfavorable biological and mechanical location for nonvascularized autologous bone transplants. The authors present the results of a multidisciplinary treatment protocol for rehabilitation of extreme mandibular and maxillary atrophy by use of the vascularized fibular flap. This protocol includes bone augmentation, implant surgery, soft-tissue management, and prosthetic restoration. Since 1993, 18 patients with a mean age of 47.5 years presented with extreme mandibular and/or maxillary atrophy and underwent alveolar crest augmentation with vascularized fibular flaps. Bone healing was achieved in 17 of the 18 patients. Seventy-three osteointegrated implants were inserted in 12 of 17 fibular flaps. Altogether, 62 implants were loaded and 11 dental prostheses were made. Average follow-up of the loaded implants was 41 months. The success rate of loaded implants was 100 percent. The authors strongly recommend the use of the fibular bone flap when dealing with extreme atrophy of the mandible and maxilla and suggest the protocol outlined in this review.
