〔Abstract〕 All of 231 patients included 293 zirconia or metal-based single crowns and 76 FDPs were evaluated. The estimate cumulative success rates of zirconia ceramic group and metal ceramic group were 79.61% and 84.74% respectively, and the estimate cumulative survival rates were 90.29% and 91.58%. There was no significant difference between the two groups in terms of success and survival rate. The chipping rate in zirconia ceramic group was 12.62% and 5.79% in metal ceramic group, there was significant difference between the two groups. The success and survival rates for FDPs were 75.00% and 88.16% respectively.
