Implant-supported hybrid prostheses have become popular solutions when treating patients with terminal dentitions or who are completely edentulous. Since the implementation of osseointegrated dental implants to treat edentulism, multiple prosthetic designs and materials have been used for full-arch fixed hybrid prostheses. While these restorations can be highly successful, the most common restorative failures are attributed to lack of prosthetic space or a framework without passive fit, consequently leading to possible chippings, delamination, and/or fractures. This article reviews the clinical and laboratory steps for fabrication of definitive implant-supported hybrid prostheses with the implementation of bone reduction guides, implant osteotomy guides, and immediate provisionalization using digital manufacturing technologies.
当治疗终端牙列或完全无牙患者时，种植体支持的混合修复体已成为一种流行的解决方案。自从将骨整合牙科植入物用于治疗无牙颌以来，已经使用了多种修复体设计和材料用于全口固定混合修复体。虽然这些修复体可以非常成功，但最常见的修复体失败归因于缺乏修复空间或没有被动配合的框架，因此可能导致碎裂、分层和/或骨折。本文综述了使用骨减少引导器、种植体截骨引导器和数字化制造技术进行即刻临时修复，制作最终种植体支持的混合修复体的临床和实验室步骤。
