%0 Journal Article %T Computer aided planning for orthognatic surgery %A Matthieu Chabanas %A Christophe Marecaux %A Yohan Payan %A Franck Boutault %J Physics %D 2006 %I arXiv %X A computer aided maxillofacial sequence is presented, applied to orthognatic surgery. It consists of 5 main stages: data acquisition and integration, surgical planning, surgical simulation, and per operative assistance. The planning and simulation steps are then addressed in a way that is clinically relevant. First concepts toward a 3D cephalometry are presented for a morphological analysis, surgical planning, and bone and soft tissue simulation. The aesthetic surgical outcomes of bone repositioning are studied with a biomechanical Finite Element soft tissue model. %U http://arxiv.org/abs/physics/0610213v1
