摘要
目的:探讨作为前牙美容修复的金瓷、全瓷、树脂材料的颜色和光学特性是否与Vita比色板一致、具有相同的比色参照性。方法:对Vita比色板,及同色系相同部位定制的VITAVMK95金-瓷修复材料、Artglass树脂修复材料、全瓷(In-Ceram)修复材料的颜色样本进行了色度值测量与色差分析。结果:Vita比色板与全瓷修复材料、Artgalss修复材料的颜色样本平均色差ΔE均小于3NBS单位;与金-瓷修复材料颜色样本的色差均值为ΔE=13.78,大于人眼可接受的范围,有明显差异(P<0.01)。结论:Vita比色板与金-瓷修复材料的颜色属性存在较大的偏差,而与全瓷修复材料、Artgalss树脂修复材料偏差较小。因此其比色参照性有待于进一步研究改进。
Objective：To observe the consistence of the color and optical parameters of metal-ceramic, all-ceramic and composite resin with Vita Classical shade guides. Methods：Specimens of VITA VMK95 metal-ceramic, In-Ceram all-ceramic and Artglass composite resin according to the same area with Vita Classical shade guide were made respectively. AEab^＊ , L^＊ , a^＊ , b^＊ between specimens and shade guide were calculated. Results ：The mean AE between shade guide and all-ceramic or composite resin was less than 3 NBS. The mean AE between shade guide and metal-ceramic material was 13.78 NBS, the significant difference could be identified by visual determination （ P 〈 0.01 ）. Conclusion： The optical parameters of all-ceramic and composite resin were similar to those of Vita Classical shade guide. While there is significant difference between the optital parameters of Vita Classical shade guide and metal-ceramic material.
