This review article evaluated biomechanical studies, finite element analyses, and clinical papers on the prosthetic and surgical principles for the survival of implants when reconstructing the edentulous mandible, including the use of a three-implant-supported fixed prosthesis.
A comprehensive search of studies published from 1983 to December 2017 listed in the PubMed/MEDLINE databases was performed. Relevant studies were selected according to predetermined inclusion and exclusion criteria.
The initial database search yielded 942 titles. After filtering, 157 abstracts were selected, with 68 articles considered relevant and included. Consensus among authors was identified in regard to the number and the distribution of implants; limiting or eliminating distal cantilevers; and the principles of biomechanical loading of a cross-arch splinted prosthesis.
The result of this review suggests that reconstruction of the edentulous mandible with a fixed prosthesis using three, four, or six implants is a viable treatment option. However, when using three implants, wider-diameter implants are recommended for favorable force control.
本综述文章评估了生物力学研究、有限元分析以及关于无牙颌种植体修复的假体和手术原则的临床文献，包括使用三种植体支持的固定义齿。
对 1983 年至 2017 年 12 月期间在 PubMed/MEDLINE 数据库中列出的研究进行了全面检索。根据预定的纳入和排除标准选择相关研究。
最初的数据库搜索产生了 942 个标题。经过筛选，选择了 157 篇摘要，其中 68 篇被认为是相关的并被纳入。作者之间就种植体的数量和分布、限制或消除远端悬臂以及交叉拱形夹板修复体的生物力学加载原则达成了共识。
本综述的结果表明，使用三、四或六枚种植体的固定义齿修复无牙颌是一种可行的治疗选择。然而，当使用三枚种植体时，建议使用更大直径的种植体以进行有利的力控制。
