This research addresses modeling the kinematic and dynamic response of the human jaw system, from an analytical, virtual and experimental viewpoint. Kinematic parameter variation laws have been identified which define the mandible motions on a human skull and a human subject through experimental measurements. A virtual human skull reconstruction it is presented, by using an original method and this was parameterized on a modular concept, based on the anatomy of a human subject. For this, equivalent mechanisms of the human jaw were elaborated and these represent a base frame for inverse kinematic modeling in an analytical way. This analysis has been validated with a numerical processing algorithm in order to identify the generalized coordinate variation laws. Human jaw muscle groups have been modeled as linear actuators. The aim of this research is to perform a dynamic analysis by using the finite element method, for stress and deformation distributions determination, on normal or critical motions cases. Mathematical and virtual models, created through a modular construction, easily permit us to evaluate in a dynamic mode different dental prostheses used in dentistry domain.
