Paper Title:
Soak Colored Zirconia Ceramics and its Colorimetric Plate
  Abstract

Objective: To test specimens of soak-colored Vita In-Ceram YZ zirconia ceramics and the colorimetric data of staining solution colorimetric plate. Methods: five sets of specimens were prepared, soaking and coloring them with LL1 to LL5 staining solution for 2 min respectively. Specimens were sintered for 2 h at 1530°C, and grinded one side of the specimens to 1.5 mm in thickness. The colors of the specimens and staining solution colorimetric plate were tested by spectrophotometer in black background. The chromatic aberration between the specimens and colorimetric plate were calculated as well as measured the lightness difference, hue angle difference, and saturation difference. Results: the colorimetric data of the dyed specimens are L: 59.81 ~ 78.93; a: 0.36 ~ 9.36; b: 19.62 ~ 26.91. The color space of the specimens and staining solution colorimetric plate was similar and the chromatic aberration was 4.02-6.96 NBS units. The biggest difference between them was the hue angle difference, mean 7.38, followed by the saturation difference, mean 2.31; minimum lightness difference, mean 2.29. Conclusion: staining solution colorimetric plate was suitable to be colorimetric reference for the color-matching of the basic layer of the ceramic. Proper chromatic aberration leaves color revision space for the translucent porcelain veneer.
