Outline of Final Research Achievements

I tried to quantify bone remodeling rate with micro-CT images of rat. Besides, I was planning to program the value to finite element analysis enabled to achieve the purpose. However, tooth of rat was too small and it took a lot of time to make the finite element model. Moreover, it was necessary that the relationship the value of stress on the point of the surface of periodontal ligament and its distance from initial position to final to clarify bone remodeling rate, but because so much points were exist and verification among the number of teeth were needed, bone remodeling rate has not been clarified yet. In other times, simulation of tooth movement was only the initial tooth displacement, nevertheless, long time tooth movement for more than several months has been able to do.
