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- 32 1色差计 (D6 5光源 )以 CIE1976 - L* a* b*色度系统分别对 15 0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 6 6 .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。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.
