This paper presents a surgical simulator for orthognathic surgery based on the integration of dental models and 3D cephalometry. The objective of dental models integration is to make coherent informations gathered from different sources (occlusal analysis and CT scan), and for that purpose, a system using a 3D optical localizer is used. The 3D Cephalometry analysis is used for the detection of dysmorphosis and surgical planning. This cephalometry integrates the Inferrence process for improving the surgical system. Both elements of our simulator have been implemented and technically validated with success.
