Abstract：
Appropriate load distribution among the supporting elements is essential for the long-term success of implant-assisted removable partial dentures; however, there is little information available on load distribution.
This study aimed to evaluate the effect of implant location on load distribution in implant-assisted removable partial dentures by reviewing in vitro models and finite-element analysis studies.
English-language studies which examined the load distribution of implant-assisted removable partial dentures and were published between January 2001 and October 2022 were extracted from PubMed, ScienceDirect, and Scopus online databases, and manual searching. Two reviewers selected the articles based on the predetermined inclusion and exclusion criteria, followed by data extraction and analysis.
Forty-seven studies were selected after evaluating the titles and abstracts of 264 articles; two were identified manually. After screening the text, 12 studies were included: six in vitro model experiments and six finite-element analysis studies. All included studies used a mandibular free-end missing model (Kennedy Class I or II). The influence of implant location on load distribution to the abutment tooth, implant, and mucosa under the denture base was summarized in three cases: implant at the premolar, first molar, and second molar region. Due to differences in the measurement method of load distribution and loading condition to the denture, the results differed among the studies.
The implant location in implant-assisted removable partial dentures can affect load distribution to the supporting elements, such as the abutment tooth, implant, and mucosa under the denture base.

摘要：
背景：支撑元件之间的适当载荷分布对于植入物辅助的可移动局部义齿的长期成功至关重要；但是，关于负载分布的信息很少。
目的：本研究旨在通过回顾体外模型和有限元分析研究，评估种植体位置对种植体辅助可摘局部义齿中载荷分布的影响。
方法：在2001年1月至2022年10月之间发表的研究种植体辅助可摘局部义齿的负荷分布的英文研究摘自PubMed，ScienceDirect,和Scopus在线数据库，手动搜索。两名审稿人根据预定的纳入和排除标准选择了文章，然后进行数据提取和分析。
结果：在评估了264篇文章的标题和摘要后，选择了47项研究；其中两项是手动确定的。筛选文本后，包括12项研究：6项体外模型实验和6项有限元分析研究。所有纳入的研究均使用下颌游离端缺失模型（肯尼迪I级或II级）。种植体位置对基牙载荷分布的影响，植入物,并总结了三种情况：前磨牙种植，第一磨牙,和第二磨牙区。由于义齿的载荷分布和载荷条件的测量方法不同,研究结果不同。
结论：种植体辅助可摘局部义齿中的种植体位置可影响支撑元件的载荷分布，例如基牙，植入物,和义齿基托下的粘膜。
