Ex vivo occlusal model. (a) Optical image of a cross-section through the mesial cusp region of a human mandibular second molar indicating the enamel thickness used in this study. BCT: Buccal cusp thickness (2.1 mm); ICS: Enamel thickness in the internal cusp slope region (1.8 mm). (b) Occlusal contact on the functional cusps of a mandibular molar. (c) and (d) Schematic representations of the box highlighted area in (b), used in finite element and analytical stress analyses for blunt loading of ceramic veneer bonded to enamel and dentin, respectively. The symbol P represents load, and R represents cementation surface radial cracks.
