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
