The movement of teeth in orthodontic therapy is made by the applied pressure or displacement through bracket and wire. In this research, we made virtual teeth on the computer and simulated the behavior of displacement by giving them external pressure through bracket and wire. The followings are the results obtained by the present study. The movement behavior of teeth obtained were similar to the one observed by clinical, and was able to describe the metastasis behavior of teeth in the orthodontics department correction qualitatively. The displacement of teeth is not done sufficiently by only pulling the both side of wire and we couldn't get the enough displacement if we don't consider virtual pliability intermediate layer that assume the spring-back or bone remodeling.
