Finite element model of facial soft tissue. Effects of thickness and stiffness on changes following simulation of orthognathic surgery.
A study was conducted to investigate the influence of the thickness and stiffness of soft tissue on changes following orthognathic surgery. The finite element method was used to simulate surgery. Three finite element models with normal thickness and stiffness, twice the thickness and twice the stiffness were made in preparation for the simulation. The thickness of soft tissue had more effect than stiffness on posterior and vertical changes.
