Outline of Final Research Achievements

The aim of this study was to clarify the postoperative changes after orthognathic surgery from biomechanical point of view. We tried to evaluate the postoperative displacement of bony segment using finite element analysis under the situation of mastication force loading. As a result of this study, the postoperative changes of bony segment after orthognathic surgery which was observed in the clinical situation could be reproduced and the postoperative prediction using finite element analysis must be useful for diagnosis and planning for surgical orthodontic treatment.
