Abstract

In this paper, we propose a computer aided diagnosis system that facilitates the drafting of treatment plans, the simulation of orthognathic surgery and the prediction of postoperative features. The three-dimensional (3D) display of the oral and maxillofacial region is very efficient for dentists to understand a patient symptom and draft an appropriate treatment plan. To achieve this purpose, we propose a construction method of a 3D head model, which consists of soft and hard tissue. Utilizing feature points extracted from ortho-directional X-ray images and facial images, a standard head model can be modified to adapt an individual head shape. Using this head model, we can predict surgical modification of soft and hard tissue.
