| 摘 要： | 目的：观察VITA比色板比色制作的金瓷修复体色彩复现率。方法：用美能达CR－321色差计（D65光源）以CIE1976－L^*a^*b^*色度系统分别对150个上颌中切牙及其金瓷修复体色度值进行测色、计算色彩复现率并进行统计。结果：临床视觉比色法的色彩复现率为33.9%,色彩偏差为66.1%。结论：常规比色制作出的金瓷修复体的色彩复现率较低,在临床比色过程产生的色彩偏差较大。

| Abstract: | Objective: To study the color reproduction ratio of metal ceramic restoration in clinic. Methods:The color of 150 maxillary incisors and its metal ceramic restorations was measured by MinoltCR 321 chromaticity instrument(D65 daylight simulator inside),the color reproduction ratio was calculated with CIE 1976 L*a*b* system. Results: The color reproduction ratio of metal ceramic restoration measured by clinical eye evaluation was 33.9%.Color error ratio was 66.1%. Conclusion: The color reproduction ratio measured by eye evaluation is low and the color error ratio is high. |
