Development and Problems of Biomechanical Study on Implants Based on in Vivo Measured Load

Abstract

The structure of peri-implant bone is continuously changing because of bone remodeling induced by mechanical stress, which can cause bone resorption and/or bone mineral density reduction. Therefore, for preserving peri-implant tissue in a healthy condition for a long time, it is essential to design an optimized implant treatment plan considered the relationship be tween the force and bone response. To clarify this relationship, it is necessary to know the actual conditions of in-vivo force exerted on implants via the prostheses while in use. In this paper, we outline the influence of the force exerted on implants on peri-implant bone based on a review of the literature. To date, several methods have been used to measure the force on implants in-vivo. Therefore, studies that analyzed bone remodeling activity using actual in-vivo measured force are also sum marized. Finally, a future vision of implant treatment planning based on force optimization is given.
