Abstract

In orthognathic surgery, the framing of 3D-surgical planning that considers the balance between the front and back positions and the symmetry of the jawbone, as well as the dental occlusion of teeth, is essential. In this study, a support system for orthodontic surgery by visualizing the changes in the mandible and the occlusal condition have been developed. This system enables surgeons to determine the optimum position of a jawbone and teeth alignment at the same time. By integrating the manipulation of a tooth model and the 3D-CT skeletal images that are simultaneously displayed in real-time, the optimal determination of the mandibular position and posture is possible. The realistic operation of the entity model and the virtual 3D image display enabled the construction of a surgical simulation system that involves augmented reality.
