肩台瓷金瓷冠在前牙修复中的临床效果观察

Clinical observation of the metal-ceramic crowns with shoulder porcelain of anterior teeth

目的分析肩台瓷金瓷冠在前牙修复中的临床效果。方法根据纳入标准分别对42颗肩台瓷金瓷冠、44颗镍铬合金烤瓷冠修复1年后的临床效果进行观察对比,评价其结果。结果 2组间在颜色、外形、边缘密合性、牙龈健康方面有差异但无统计学意义。在牙龈灰线、边缘变色方面有差异,且差异有统计学意义。结论肩台瓷金瓷冠在前牙修复中有较好的美观效果。

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.
