The aim of the paper is a stress-strain analysis of the temporomandibular joint (TMJ) with subtotal replacement. The temporomandibular joint is a complex, sensitive and highly mobile joint which works bilaterally so each side influences the contralateral joint and because of this the distribution of the stresses is changed in the healthy joint as well.
Detailed knowledge about function these are necessary for clinical application of temporomandibular joint prosthesis and also help us estimate the lifetime of the prosthesis a possibilities of alteration in the contra lateral joint components. The mathematical model of TMJ with replacement is based on the theory of semi-coercive unilateral contact problems in linear elasticity.
The numerical solution is based on finite element approximation. The obtained numerical results will be discussed.
