Abstrakt:	The problem of rational designing of ceramic and metalloceramic dentures is considered. The evaluation of the stress-strain state and the solution of the boundary inhomogeneous elastoplastic problem are used for determining the critical values of the amplitudes of all-ceramic cusps. The effect of the basis of the inhomogeneous structure on the changes in the angles of critical loads at which the prosthesis functions reliably up to the appearance of irreversible phenomena (cleavage of the ceramics, basis fracture) is estimated.
