Abstract
The movement of teeth in orthodontic therapy is made by the applied pressure or displacement via the bracket and wire system. The previous study revealed that enough movement of teeth could not be obtained as long as continuum models were considered for teeth and their surrounding tissues. This paper proposes a new orthodontic mandible model that takes into account the springback of the wire and the remodeling of the alveolar bone. The metastasis behavior of teeth simulated is similar to the one observed in an orthodontic therapy clinic. Sufficient amount of teeth movement is obtained by the springback of the wire but not by only pulling the both sides of the wire.
