Three-dimensional finite element models for the bilayered ceramics subjected to a bite load of 300 N were developed. Bilayered structures of porcelain with thicknesses of 0.3, 0.4, and 0.5 mm, and a core thickness of 1.0 mm, were evaluated. Stress analysis demonstrated that the peak value of principal tensile stress, which occurred at the surface of the porcelain, decreased with increasing contact radius, but was independent of the porcelain thickness. For a contact radius of 0.2 mm, the peak value of principal tensile stress was much higher than the mean bending fracture stress of the porcelain. The results indicated that Herztian cone cracking was the domimant fracture mode of bilayered ceramics. For a contact radius was 0.7 mm, however, the peak value of principal tensile stress was much lower than the mean fracture stress of the porcelain. The results showed that the fracture mode of an all ceramic crown under bite load was dependent on the occlusal contact area. For the conditions analyzed in this study, we concluded that contact area had a major influence on the stress distribution and fracture mode of bilyered ceramics.","subitem_description_type":"Other"}]},"item_10002_full_name_75":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"4240","nameIdentifierScheme":"WEKO"}],"names":[{"name":"WAKAMATSU,
