| Research Abstract |
The purpose of this study is to find the knowledge of the bone resorption around the implant neck by analyzing the wave propagation in the thinning model of trabecular bone. After measuring the pig bone, the implant body and supra-structure by micro-focus x-ray CT, and making the STL data of the implant and 3D model of trabecular bone, and the change of stress of bone was analyzed by finite-element analysis. In the result, on putting the load to the implant, the stress was recognized in the cortical bone and trabecular bone, and as the decrease of the load, the stress of trabecular bone was decreased, and finally only in the cortical bon the stress was recognized.
