摘要：

目的　探讨计算机辅助设计和制造(CAD/CAM)切削陶瓷Vita MarkⅡ的遮色能力,及此能力与厚度和色系间的关系。方法　Vita MarkⅡA3C/18和A2C/18两个色系的0·5 mm,1·0 mm和1·5 mm厚度的试件样本各5 个,覆盖在模拟变色牙的底质上,测量其颜色变化。结果　不同厚度和色系的Vita MankⅡ的遮色能力之间存在显著性差异(P<0·01), 0·5 mm,1·0 mm和1·5 mm Vita MarkⅡA3C/18和A2C/18遮色后,△E分别为15·181, 17·691, 19·667和15·653, 16·880, 18·002。结论　Vita MarkⅡ具有良好的遮色能力,且随厚度增加而增加;在作为瓷贴面时,A2C/18遮色能力略好于A3C/18;而作为嵌体等修复时,A3C/18遮色能力更强。

Abstract:

Objective　The purpose of this study was to evaluate the color masking ability of Computer Aided Design/ ComputerAided Manufacture(CAD/CAM) machining ceramic Vita Mark II, this ability was affected by thickness and shade. Methods　Each of 5 specimens of 0·5 mm, 1·0 mm and 1·5 mmVitaMark II A3C/18 and A2C/18 were prepared and the color change was measured after the substrate simulating stained teeth was covered with the specimen.Results　Statistically significant differences (P<0·01) were recorded in the substrates covered with different thickness and shade of Vita Mark II. The color changes (△E) were 15·181, 17·691, 19·667 and 15·653, 16·880, 18·002 afterthe substrateswere coveredwith 0·5 mm, 1·0 mm and 1·5 mmVitaMarkⅡA3C/18 and A2C/18.Conclusion　As a dental material, CAD/CAMVitaMark II has high quality to mask the underlying color. Being a veneer, the masking abilitywith A2C/18 is better than thatwith A3C/18, but being an in- lay, the result is reverse.
