Role of Dental Implants in Maxillofacial Rehabilitation
摘要
Dental implants play a crucial role in the rehabilitation of patients who have undergone segmental mandibulectomy or maxillectomy due to oral cancers. Such surgeries often lead to significant loss of jaw structure, affecting mastication, speech, and aesthetics.Complete rehabilitation of all oral functions following the treatment for cancers of the oral cavity is desirable, yet a difficult goal to achieve. Reconstructive surgeries using free bone flaps—like fibula, iliac crest, or scapula—help restore continuity of the mandible and provide a base for implant-supported prosthetic rehabilitation.
ObjectiveTo highlight the role and outcomes of dental implants in free bone flap reconstruction for patients undergoing oral cancer resection.The ability to achieve total rehabilitation of all oral functions is, however dependent on tumor factors, patient factors, treatment related factors and physician factors.
MethodsA review of clinical approaches to implant placement in vascularized free bone flaps such as fibula, scapula, and iliac crest was conducted. The principles of bone and soft tissue management were discussed, emphasizing early versus delayed implant placement, and the influence of radiotherapy and flap type on implant success.
ResultsFree bone flap reconstructions provide a reliable foundation for dental implants, allowing effective prosthetic rehabilitation. Earlystage oral cancer cases are usually treated surgically, enabling reconstruction and later implant placement for functional and aesthetic restoration. However, achieving ideal outcomes in all patients remains challenging due to variations in bone volume, flap anatomy, and postoperative complications.
ConclusionDental implants in free bone flaps significantly improve quality of life by restoring mastication, speech, and aesthetics after major jaw resections. The fibula flap remains the preferred option due to its favorable bone length, height, and vascularity, supporting successful implant-based oral rehabilitation.
