Osseointegrated implants in craniofacial reconstructions improve prostheses retention and stability and comfort and safety for a patient. According to biomechanical principles, the treatment success regarding osseointegration maintenance depends on an adequate surgical technique associated to a retention system that provides favorable tension distribution to implants. Furthermore, patient expectation, esthetics, function, and anatomic limitations must be evaluated during treatment planning. Therefore, the aims of this study were to present available retention systems to implant-supported craniofacial prosthesis and to highlight the advantages, indications, and limitations. A literature review was conducted through a MEDLINE search. Sixteen articles and 2 textbooks met the inclusion criteria and were included in the review. It was concluded that the success of craniofacial rehabilitation with implants depends on an adequate surgical technique and an adequate selection of a retention system.
颅面重建中的骨整合植入物可改善假体的固位、稳定性以及患者的舒适度和安全性。根据生物力学原理，骨整合维持的治疗成功取决于与固位系统相关的适当手术技术，该固位系统能为植入物提供有利的张力分布。此外，在治疗计划制定过程中必须评估患者的期望、美观、功能和解剖学限制。因此，本研究的目的是介绍用于种植体支持的颅面假体的现有固位系统，并突出其优点、适应症和局限性。通过医学文献数据库（MEDLINE）检索进行了文献综述。16篇文章和2本教科书符合纳入标准并被纳入综述。得出的结论是，种植体颅面修复的成功取决于适当的手术技术和固位系统的适当选择。
