Figure 5. Equivalent stress distribution of enamel in the three groups
a-c: distribution of equivalent stress of enamel, with the maximum stress in each restoration model mainly concentrated in the enamel at the cavosurface and the cervical enamel-dentin interface; d-f: distribution of equivalent stress of enamel in the buccolingual direction; g: maximum stress of enamel; group A: the cavosurface angle is 90°; group B: the cavosurface angle is 120°; group C: the cavosurface an-gle is 135°
