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.
本体内研究的目的是评估使用压电换能器固定种植体上部结构的夹板对支持固定上部结构的种植体施加的三维力的生物力学影响。测量设备设置在下颌右侧第二前磨牙和第一磨牙的种植体固位器中。在咬牙时，如果与未夹板的对照种植体相比，夹板固定的种植体的力大小更均匀地分配到两个种植体上。然而，在蜡咬时，负载分配的这种均衡并不明显。夹板固定种植体支持的固定上部结构会影响种植体上的力，尤其是在咬牙时。
