| Research Abstract |
The purpose of this study was to establish a simulation model to predict bone tissue changes by occlusal force by means of 3-D finite element analysis. We established rat implant occlusion model first. Then, we used micro CT to have digital data of 3-D structure of the implant with surrounding bone tissue. Using 3-D finite element analysis program, we applied occlusal force to the implant and seek some correlation between the force distributions and bone tissue changes investigated by histological sections. As a result, we found that there were some correlations between those and it was shown that the bone tissue changes upon occlusal loading could be predicted by 3-D finite element analysis. The precision should be verified by further investigation yet.
