001). Consistent with the weaker edge crack resistance, the 120° group experienced the greatest wear (p=0.008), and the wear depth in the enamel of the 75° group exceeded that of the 90° group (p0.001) in the early stage (5×102 cycles). However, no significant difference in the wear depth (p0.147) and morphology were found at the later wear stage among the three groups. Within the limitations of this study, minimally invasive preparations with 120° and 75° marginal angles can result in early sever damage at the ceramic inlay
