The aim of this study was to evaluate stress distribution in peri-implant bone and to investigate the influence of splinting implants by finite element analysis (FEA) with in vivo loading data. The magnitude and direction of the force exerted on implants during maximal voluntary clenching of a subject were recorded with 3-D piezoelectric force transducers. FEA using in vivo loading data was conducted on splinted and non-splinted models with two implants. Overall, the splinted model reduced stress in peri-implant bone in comparison with the non-splinted model.
本研究的目的是通过有限元分析（FEA）结合体内加载数据来评估种植体周围骨组织的应力分布，并研究种植体夹板固定的影响。使用三维压电力传感器记录受试者最大自主咬合时施加在种植体上的力的大小和方向。对有两个种植体的夹板固定模型和非夹板固定模型进行了结合体内加载数据的有限元分析。总体而言，与非夹板固定模型相比，夹板固定模型降低了种植体周围骨组织的应力。
