Research Abstract

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.
