Fig. 4.
The Mohr-Coulomb stress ratio distributions in the residual tooth structure under vertical and lateral loading.
B = buccal; D = distal; FRC = fiber-reinforced composite; GAC = gold alloy cast; M = mesial; P = palatal; yellow arrow = maximal Mohr-Coulomb stress ratio; red curve = high Mohr-Coulomb stress ratio regions.
