Osseointegrated implants can be applied to facilitate retention, stability, and support for facial and intraoral prostheses used to restore head and neck defects. At the University of California, Los Angeles, Maxillofacial Prosthetics Clinic, retrospective studies have indicated that in nonirradiated maxillectomy patients, implant survival rates are 82.6 percent. In mandibles reconstructed with fibula free flaps, survival rates are 94.6 percent. Similarly, high implant survival rates have been observed for most sites used to support facial prostheses. Cumulative six-year survival rates for auricular sites exceed 95 percent and for floor of nose sites, success rates exceed 87 percent. However, survival rates are low (53 percent) for implants placed in the frontal bone for retention of orbital prostheses and even lower for irradiated bone sites ranging from 63 percent in the maxilla to 27 percent in the orbit.
骨结合种植体可用于辅助修复头颈部缺损的面部和口腔内假体的固位、稳定和支撑。在加利福尼亚大学洛杉矶分校颌面修复诊所，回顾性研究表明，在未接受放疗的上颌骨切除患者中，种植体存活率为82.6%。在采用游离腓骨瓣重建的下颌骨中，存活率为94.6%。同样，在大多数用于支撑面部假体的部位也观察到了较高的种植体存活率。耳部部位的六年累积存活率超过95%，鼻底部位的成功率超过87%。然而，用于眶部假体固位的额骨种植体存活率较低（53%），而在放疗后的骨部位，存活率更低，在上颌骨中为63%，在眶部为27%。
