A method for simulating the movement of teeth, jaw and face caused by orthognathic surgery is proposed, characterized by the use of 3D cephalometric data for 3D simulation. Computed tomography data are not required. The teeth and facial data are obtained by a laser scanner and the data for the patient’s mandible are reconstructed and integrated according to 3D cephalometry using a projection-matching technique. The mandibular form is simulated by transforming a generic model to match the patient’s cephalometric data. This system permits analysis of bone movement at each individual part, while also helping in the choice of optimal osteotomy design considering the influences on facial soft-tissue form.
