Finite element analysis of the residual thermal stresses on functionally gradated dental restorations

The aim of this work was to study, using thefinite element method (FEM), the distributionof thermal residual stresses arising in metal–ceramic dental restorations after cooling fromthe processing temperature. Three different interface configurations were studied: withconventional sharp transition; o...
