Abstract

It is clinically important to accurately predict facial soft tissue changes prior to orthognathic surgery. However,the current simulation methods are problematic,especially in clinically critical regions. We developed a two-stage finite element method (FEM) simulation model with realistic tissue sliding effects. In the 1st stage,the facial soft-tissue-change following bone movement was simulated using FEM with a simple sliding effect. In the 2nd stage,the tissue sliding effect was improved by reassigning the bone-soft tissue mapping and boundary condition. Our method has been quantitatively and qualitatively evaluated using 30 patient datasets. The two-stage FEM simulation method showed significant accuracy improvement in the whole face and the critical areas (i.e.,lips,nose and chin) in comparison with the traditional FEM method.
