The Investigation of the Occlusion of Implants-supporting FixedProstheses on the Analysis of Three Dimensional Loads in vivo

施加在种植体上的三维载荷是种植体支撑固定修复体生物力学控制的重要参数。在治疗过程中，不仅要考虑载荷的大小，还要考虑载荷的方向，这样才能获得良好的预后。在本研究中，我们开发了一种基于口颌系统坐标的体内三维载荷测量系统，并对载荷进行了分析，明确了假体参数对载荷的影响。

Three-dimensional (3-D) loads exerted on dental implants are important parameters in the biomechanical control of implant-supported fixed prostheses. It is critical to consider not only the load magnitudes but also the load directions during function to obtain a good prognosis of that treatment. In this study, we developed a system for measuring in vivo the 3-D loads exerted on dental implants and for analyzing the loads on the basis of the stomatognathic system coordinates and clarified the effects of the prosthetic parameters on the loads.
