Abstract:
A 63-year-old man underwent segmental mandibulectomy for ameloblastoma, followed by fibula free-flap reconstruction. As the bone volume was inadequate, guided bone regeneration (GBR) was performed using iliac particulate cancellous bone and marrow, titanium mesh, and tenting screws. After consolidation, 4 implants were placed, and restoration was completed with a computer-aided design and computer-aided manufacturing titanium bar and LOCATOR-retained overdenture. This staged approach ensured stable implant placement and successful rehabilitation. At 1 year postoperatively, the patient's appearance and masticatory function had improved significantly, with no peri-implant or prosthetic complication. The combined application of GBR and a 2-stage protocol after fibula flap surgery enables the predictable achievement of functional reconstruction.
