Typically, full arch reconstruction of edentulous ridges requires five to 10 dental implants; however, some patients demanding fixed implant-supported prostheses are not able to medically or economically afford complex bone grafts and/or a greater number of implants. These situations could pivot the treatment plan toward the All-on-4 protocol. Nevertheless, due to less implant support in this treatment option, mechanical and biological complications might arise. This article describes the treatment of a fully edentulous patient with two types of fixed implant-supported prostheses on four dental implants along with the following complications.
通常情况下，无牙颌牙槽嵴的全牙弓重建需要5至10颗牙种植体；然而，一些需要固定种植体支持式修复体的患者在医学或经济上无法承受复杂的骨移植和/或更多数量的种植体。这些情况可能会使治疗方案转向All-on-4方案。尽管如此，由于该治疗方案中种植体支持较少，可能会出现机械和生物学并发症。本文描述了一名全口无牙患者在四颗牙种植体上使用两种固定种植体支持式修复体的治疗情况以及以下并发症。
