背景颜色对4种全瓷底层材料饰瓷后颜色的影响
Influence of background color on four veneered dental ceramic core material
摘要
Abstract
Objective To investigate the influence of background color on veneered In-Ceram and Cercon dental ceramics including Vita ln-Ceram Electroformed Alumina (AL2),Electroformed Zirconia (Z21),Cercon base color Zirconia and Cercon base Zirconia.Methods The colorimetric values of all the materials on noble metal,Ni-Cr alloy,silver amalgam and resin background were measured with a spectrocolorimeter,and the color difference among the groups was calculated.Results After veneered,the color difference of Z21 Electroformed Zirconia was more distinct against the background of silver amalgam than against the backgrounds of noble metal and resin,but the color differences of the 4 veneered dental ceramics against different backgrounds were unidentifiable by human eyes (△ E<1.5).Conclusion After veneered,AL2 electroformed alumina,Z21 electroformed zirconia,Cercon base Zirconia and Cercon base color Zirconia are less influenced by the background color,and covering the background color is therefore not necessary.关键词
