摘要/Abstract

摘要： 目的

分析不同陶瓷材料瓷贴面在四环素牙背景下的色彩学性能和半透性。

方法

采用热压铸造和分层堆塑方法分别制作总厚度0.50 mm的A1、A3、B2、B4色玻璃陶瓷贴面和长石质瓷贴面试件各10片，利用分光光度计测量试件在模拟四环素牙背景及黑白背景上的L*、a*、b*值，计算试件在模拟四环素牙背景上与背景颜色的色差ΔE₀₀1、与试件在白背景上色差ΔE₀₀2及试件的TP值。

结果

IPS d.SIGN遮色长石质瓷试件的ΔE₀₀1显著大于IPS e.max Press LT玻璃陶瓷试件，B4色瓷试件的ΔE₀₀1显著大于其他色号（P<0.05）。遮色长石质瓷试件ΔE₀₀2均小于1.25，玻璃陶瓷试件ΔE₀₀2均大于2.23，但各颜色组间差异无统计学意义（P>0.05）。遮色长石质瓷试件TP值显著小于玻璃陶瓷（P<0.05），不同陶瓷颜色组间差异无统计学意义（P>0.05）。

结论

0.50 mm厚IPS d.SIGN遮色长石质瓷贴面美白改色四环素牙可获得理想的色彩学性能，但其半透性不理想，远差于IPS e.max Press LT玻璃陶瓷贴面。

Abstract: Objective

To analyze the chromatic properties and translucency of porcelain veneers made from different ceramic materials against the background of tetracycline-stained teeth.

Methods

Porcelain specimens (A1, A3, B2, B4) measuring 0.50 mm in thickness were prepared by heat-press casting and layering. The L*, a*, and b* values of the specimens against simulated tetracycline tooth and black-and-white backgrounds were measured by a spectrophotometer, and color differences ΔE₀₀1 between specimens on simulated tetracycline backgrounds and the backgrounds themselves and ΔE₀₀2 between specimens on simulated tetracycline backgrounds and the white background were calculated. The translucent parameter (TP) was also evaluated.

Results

The ΔE₀₀1 of feldspathic specimens (IPS d.SIGN) with the opaque layer was significantly greater than that of glass ceramic specimens (IPS e.max Press LT), and the ΔE₀₀1 of group B4 was consistently greater than those of the other color groups (P<0.05). The ΔE₀₀2 values of all feldspathic specimens with the opaque layer were less than 1.25, and the ΔE₀₀2 values of the glass ceramic specimens were greater than 2.23. However, no significant difference was observed among the different color groups (P>0.05). The TP values of feldspathic specimens with the opaque layer were significantly lower than those of glass ceramic specimens(P<0.05), but no significant difference was observed among different color groups (P>0.05).

Conclusion

When changing the color of tetracycline-stained teeth, 0.50 mm-thick IPS d.SIGN feldspathic veneers with an opaque layer provide better chromatic properties than IPS e.max Press LT glass ceramic veneers. However, the translucency of feldspathic veneers is generally poorer than that of glass ceramic veneers.
