中文摘要:
      目的:分析不同颜色Vita Alpha饰面瓷对CAD/CAM(计算机辅助设计和计算机辅助制造)氧化铝渗透陶瓷颜色的影响,并与对应的金瓷修复体相比较,为临床选色?配色提供依据?方法:将4组CAD/CAM氧化铝渗透后瓷片(ALC瓷)和10个烤瓷Ni-Cr合金试件(随机分为2组),按照常规步骤分层堆加A2/A3不透明牙本质瓷?牙本质瓷和牙釉质瓷,测量并计算各组的颜色差异?结果:实验组4组氧化铝陶瓷试件完成前后的颜色空间?对照组2组金瓷试件的颜色以及实验组与对照组之间的颜色均显示有显著性差异(P < 0.01)?结论:自制玻璃料渗透氧化铝陶瓷颜色空间均在中国人牙的色度范围内,与金瓷相比,其明亮度较高,b*轴偏黄,符合中国人牙色特点?
英文摘要:
      Objective:Compared with the porcelain-fused metal restorations,the study is to evaluate the alteration of color on CAD/CAM alumina glass-infiltrated composite with different color Vita α veneering porcelain,helping the color-selecting and color-matching in clinical practice. Methods:Four groups of CAD/CAM alumina glass-infiltrated composite(ALC) and ten porcelain-fused Ni-Cr alloys specimens(randomized into two groups) were routinely layered with A2/A3 opaque-dentine porcelain,dentine porcelain and enamel porcelain. The resulting color differences were measured and calculated. Results:There were significant color differences in four groups of ALC,two groups of porcelain-fused Ni-Cr alloys specimens and also between the experimental and control groups(P < 0.01). Conclusion:The color space of alumina self-made glass-infiltrated composite was in the range of Chinese teeth chroma. Compared with the porcelain-fused metal restorations,the color of ALC was shifted to the lightness and yellow in b*-axis,which corresponded with the characteristics of Chinese teeth.
