Finite element study to quantify the relationship between masticatory stress and prognathism

Abstract

In anthropology, the finite element method (FEM) is frequently applied to determine the validity of hypotheses concerning the adaptation of biological form to suit functionality. Different geometries are analysed, and based on the predicted displacements and/or stresses, conclusions are drawn regarding which geometry is better suited to perform a particular function. In this project, we demonstrated the ability of the FEM to predict patient-specific stress distributions due to a variation in facial form. The outcomes of this project have potential application in forensic science and facial reconstructive surgery.
