摘　　要：目的:研究DA9-7烤瓷支架钴铬合金用于烤瓷最适合的遮色瓷厚度变化的基本规律。方法:使用接触式JY9800色度计,研究DA9-7烤瓷支架钴铬合金、GiroBond NB钴铬合金和CWPA镍铬烤瓷合金和VITA VMK95 A色系瓷粉的不同瓷层厚度时,颜色变化规律,并且寻找不同的颜色瓷粉和合金组合需要的最佳遮色瓷层厚度。结果:三维和二维MANOVA分析发现,主效应"颜色"、"合金"、"瓷层厚度"对于试件颜色的影响不尽相同。DA9-7合金所需要的遮色瓷厚度依次为:0.10～0.15mm(A1),0.15～0.20mm(A2),0.15～0.20mm(A3),0.20～0.25mm(A3.5),0.25～030mm(A4)。结论:遮色瓷厚度与Co-Cr烤瓷合金修复体颜色有密切关系。Objective： This article was to investigate the fundamental rules of appropriate opaque ceramic thickness for DA9-7 Co-Cr dental alloy. Methods：A colorimeter （JY9800） was used to study the color variety of DA9-7 Co-Co dental alloy, Girobond NB Co-Co dental alloy, CWPA Ni-Cr alloy and VITA VMK95 A shade ceramic, finding the optimal opaque ceramic thickness for different combination of ceramic and alloy. Results：Opaque ceramic thicknesses for DA9-7 dental alloy were successively 0.10-0.15mm（A 1 ）,0.15-0.20mm（A2）,0.15- 0.20mm（A3）,0.20-0.25mm（A3.5）,0.25-0.30mm（A4）. Conclusions： Thickness of opaque ceramic was related with color of Co-Cr dental alloy restorations.
