Abstract

The aim of this work was to employ the Finite Element method (FE) on the study of thermal residual stresses arising in metal-ceramic dental restorations after cooling from the processing temperature. Two different interface designs were studied: conventional metal-ceramic sharp transition and a compositionally graded transition (FGM). The FE analysis was performed based on experimental data obtained for Young's Modulus and Coefficient of Thermal Expansion of the materials. Results have shown significant benefits of the FGM design over the traditional sharp transition in terms of the stress reduction and stress profile. Maximum tensile stresses were significantly reduced with the FGM design.
