Background:
Functional reconstruction of the jaw defect due to tumor resection poses a challenging problem in maxillofacial surgery. The osteocutaneous fibula free flap in combination with simultaneous or second stage insertion of dental implants has exhibited growing popularity for such reconstructions. This study was aimed at evaluating the clinical status and the success rates of dental implants inserted in fibula-free flaps for orofacial reconstruction following ablation of tumors.
Methods:
We conducted a clinical follow-up study based on 29 patients after oral tumor surgery, who received vascularized fibula bone grafts and endosseous implants for functional jaw reconstruction during a 5-year period. The follow-up protocol included clinical examination and radiological evaluation. The clinical records of the patients were reviewed retrospectively. Information on treatment modalities, dentition, implant parameters, and prostheses was collected and analyzed.
Results:
In general, a high primary stability for implants placed into the free fibula grafts was achieved. The 1-year and 5-year cumulative survival rates of the implants were 96% and 91%, respectively, using the Kaplan-Meier method. The 1-year and 5-year cumulative success rates of implants placed into the fibula bone grafts were 95% and 87%, respectively. The main reasons for failure of the dental implants were infection, tumor recurrence and soft tissue proliferation. The fibula flap presents many advantages for implant placement, but its limited height sometimes makes implant-supported prosthetic rehabilitation difficult.
Conclusions:
Vascularized fibula bone grafts provide a firm basis for the placement of dental implants in jaw reconstruction. Implants placed in fibula bone grafts were shown to integrate normally. The double-barrel technique, or increasing the height of the fibula flap by vertical distraction osteogenesis before implant placement in the mandible, is desirable from a functional and esthetic point of view.
