Objective To observe the prosthetic effects of the metal-ceramic crowns with shoulder porcelain of anterior teeth clinically.Methods Forty-two units of metal-ceramic crowns with shoulder porcelain, forty-four units Ni -Cr based porcelain -fuse -metal crowns were observed after one year through clinical methods.Results There were some differences between the two groups in color match, contour, marginal integrity and health of gum. But the difference between the two groups had no statistic significance. The differences of marginal integrity and marginal discoloration between metal-ceramic crowns with shoulder porcelain and Ni-Cr based porcelain-fuse-metal crowns had high statistic significance.Conclusion Using metal -ceramic crowns with shoulder porcelain could progress the esthetics in anterior teeth.
