Finite-element analysis is now a very important tool for biomechanical studies of bones to estimate the stresses produced by load application. Stress analysis requires an exact mechanical model if we desire valid results. This paper describes a method generating a three-dimensional finite-element model from X-ray CT data. We focused on a human mandible and proposed the modelling method. The method mainly consists of four parts. First, contour images of the shape of the mandible are extracted from the X-ray CT. Second, a surface model covered with polygons was made from the contour images. Third, an approximate model modified from a standard model was provided. Finally, we obtained an individual finite-element model by transforming the modified model so that it fits the shape of the surface model.
