STATEMENT OF PROBLEM In post-and-core crown restorations, the use of flexible posts concentrates stresses at the dentin and the use of stiff posts concentrates stresses at the interfaces. A class of inhomogeneous materials (called functionally graded materials) has been proposed for posts to resolve the weaknesses of both flexible and rigid posts. PURPOSE The purpose of this in vitro study was to design an inhomogeneous post and investigate its influence on the stress distribution of post-and… CONTINUE READING
