The tooth model was crowned with Au-Pd alloy, Ni-Cr alloy and porcelain. A load of 450 N, at an angle of 45° to the longitudinal axis was applied on the occlusal margin of the crown tooth. The tooth was assumed isotropic, homogenous, elastic and unsymmetrical. This numerical study was carried out using three-dimensional finite element models and calculation programs were prepared by the authors using FORTRAN 77. The distribution of compressive, tensile and shear stress were plotted for the dentine, dentine-metal and metal-porcelain interfaces. The highest stress values were observed when Ni-Cr alloy and porcelain was used. © 2002 Blackwell Science Ltd.EnglishBicuspidChromium AlloysCompressive StrengthCrownsDental Stress AnalysisDentinFinite Element AnalysisGold AlloysHumansMasticationMaxillaMetal Ceramic AlloysStress, MechanicalTensile Strengthalloychromium derivativegold alloyarticlecompressive strengthdental caredentinfinite element analysishumanmasticationmaxillamechanical stressmethodologyphysiologypremolar toothtensile strengthtooth crownArticle10.1046/j.1365-2842.2002.00826.x
