摘要/Abstract

摘要： ［摘要］目的评价二硅酸锂铸瓷后牙牙合贴面的临床效果。方法对12例160颗重度磨耗前磨牙和磨牙用二硅酸锂铸瓷进行牙合贴面修复，观察3年，按照美国公共卫生服务修正标准对修复体的颜色匹配、边缘着色、修复体折裂、继发龋及边缘适合度等进行评价。结果后牙牙合贴面中95.62%的颜色为A级，93.75%的修复体无边缘着色，98.13%的修复体完好无损，所有修复体中没有发现继发龋，95%的修复体边缘适合度为A级。结论二硅酸锂铸瓷后牙牙合贴面近期临床修复效果优良。

Abstract: Objective To evaluate the clinical effect of posterior teeth occlusion veneer with lithium disilicate ceramic. Methods 12 cases, 160 severely worn premolars and molars were reconstructed with occlusion veneer with lithium disilicate ceramic. After 3 years of observation, according to the revised standards of public health service in the United States, the color matching, edge coloring, fracture of restorations, secondary caries and marginal fitness of the prostheses were evaluated. Results 95.62% of the colors of the occlusion veneer in the posterior teeth were Class A. 93.75% of the prosthesis had no edge coloring. 98.13% of the restorations were intact. No secondary caries were found in all the prostheses. 92.5% of the prosthesis edge fitness was Class A. Conclusion The posterior teeth occlusion veneer with lithium disilicate ceramic has good clinical effects recently.
