Abstract - The biomechanical problem of investigating the behavior of a maxillary partial denture is treated by non-linear finite element analysis. The finite element models developed allow the solution of an inverse problem to find material data of the palatal tissue and the computation of pressure distributions between the palatal plate of the denture and the palatal tissue as well as the determination of the forces acting on the anchoring teeth. This information is essential from the physiological point of view in order to avoid configurations causing pain to the patient and to prevent the natural teeth from becoming slack. Such analyses can serve as a basis for the computer aided design of proper palatal dentures.
