하악골 신연술의 컴퓨터 가상수술

Abstract

Among three directions of distraction, the horizontal direction shows the least displacement of the condyle process and the largest overlapping surface area. We interpreted above result as the horizontal vector was the ideal direction of distraction among three directions in this patient. The mirror image of normal half side can be used as a target object of simulation surgery and also be used for evaluation of the different assumption of the surgical modalities. In conclusion, the computer simulation surgery using the mirrored image in hemifacial deformity can be an effective method for the prediction and the evaluation of the real surgery and also show the new possibility of application to the other computer simulation technology.
