摘要
目的:探讨不同桩核材料背景色对3种全瓷材料饰瓷后的颜色影响。方法:采用色差计测量各组饰瓷后试样在贵金属、镍铬合金、银汞合金和树脂背景上的色度值并计算组间色差值。结果:EmpressⅡ材料在贵金属背景色与两种非贵金属和树脂背景色之间,出现明度值和色品值的组间显著差异(P<0.05),渗透氧化铝陶瓷在不同背景色下,只出现了色品值的组间显著差异(P<0.05)。4组氧化锆试样不同背景色下的色度值无组间显著性差异(P>0.05)。结论:饰瓷后,EmpressⅡ铸瓷修复体透明度较高,受背景色的影响较大,人眼可以辨别;渗透氧化铝陶瓷受背景色影响较小,人眼不能辨别。氧化锆陶瓷不受背景色的影响。
Objective： To study the influence of background color on 3 veneered all - ceramics core materials. Methods： The color of all veneered samples that were put on noble metal, NiCr alloy, AgHg alloy and resin background was measured with chromatism instrument. Results- Under different backgrounds, there was significant difference in the L, a and b values among Empress Ⅱ samples, there was significant difference in the a and b values among In - Ceram Alumina samples, and there was no difference in the L, a and b values among In - Ceram Zirconium samples. Conclusion： After veneered,the influence of background color on Empress Ⅱ was clear, on In - Ceram Alumina was less clear, and on In - Ceram Zirconium was void.
