Abstract: The mechanical behavior of the human mandible during mastication is explored. The technology of stress analysis of the mandible is then compared with more typical engineering problems. A finite element model for the stress analysis of the mandible is presented. The results of the finite element model are then compared to simpler engineering approximations. Sensitivity of the predicted stresses to variations in the boundary conditions used in the model is explored. The treatment of mandible fractures with rigid internal fixation (RIF) will then be described. The stress distribution in a fractured mandible after RIF is presented and the model's predictions for optimal RIF plate designs are discussed.
