本体内研究的目的是利用压电传感器测量施加在支撑固定上部结构的种植体上的三维力，以评估种植体支撑上部结构的夹板的生物力学效应。在下颌右侧第二前磨牙和第一磨牙的种植固定装置中设置测量装置。在握紧时，与未夹板的对照种植体相比，夹板的两种种植体的力大小分配更均匀。然而，在咬蜡过程中，这种负载分布的均衡并不明显。种植体支撑的固定上层结构的夹板会影响施加在种植体上的力，特别是在咬合时。
The purpose of this in vivo study was to evaluate the biomechanical effects of splinting of implant-supported superstructures using piezoelectric transducers to measure the three-dimensional forces exerted on implants supporting fixed superstructures. Measuring devices were set into the implant fixtures at the mandibular right second premolar and first molar. During clenching, force magnitudes were allocated more evenly to the two implants if they were splinted compared with the unsplinted control implants. However, this equalization of load distribution was not apparent during wax biting. Splinting of implant-supported fixed superstructures affects the force exerted on implants, especially during clenching.
