Computer-Assisted Maxillo-Facial Surgery
This project aims at assisting the clinician for the planning of orthognatic surgery. The objective is to build a biomechanical model of the patient face soft tissues and to use this model in order to predict the consequences of the bone repositioning onto the soft tissues deformations. The long term goal consists in providing the surgeon a prediction of the patient aesthetics after surgery, in order to validate or to modify his osteotomy planning.
