This study aimed to evaluate the effect of the configuration of implants supporting a four-unit fixed partial denture on load distribution. An epoxy resin model missing teeth from the first premolar to the second molar was used. Three-dimensional piezoelectric force transducers were set on implants placed in the missing teeth area with a four-unit experimental superstructure. Three-dimensional loads on the implants were measured with four different implant configurations when a static load of 100 N was applied. The loads on the implants changed significantly depending on the implant number and position and the applied loading points.
本研究旨在评估种植体支持的四单位固定局部义齿的结构对负荷分布的影响。使用了一个从第一前磨牙到第二磨牙缺失牙齿的环氧树脂模型。在放置于缺失牙区域的种植体上设置三维压电力传感器，并配备一个四单位实验性上部结构。当施加100 N静载时，采用四种不同的种植体结构测量种植体上的三维负荷。种植体上的负荷根据种植体数量、位置以及施加的加载点而发生显著变化。
