目的:探讨纯钛烤瓷修复体的颜色匹配性,为临床应用提供依据。方法:分别使用Noritake Ti-22 A2色体瓷与VITA A2色体瓷,制作厚2mm、直径12mm的全瓷瓷片各6个,观察颜色,使用VITA Easyshade比色仪测量色差,并对数据进行统计学分析。结果:肉眼观察,钛瓷片与VITA普通瓷片之间未见明显差异,比色仪测量Ti-22钛瓷色差为2.53,VITA普通瓷的色差为1.4,经统计学分析,两组之间具有显著性差异(P<0.05)。结论:钛瓷的颜色匹配性比普通瓷稍差,但可以为临床所接受。
Objective: To investigate the color matching of pure titanium porcelain restoration and provide the basis for clinical application. Methods: Six Noritake Ti-22 A2 color body porcelain and VITA A2 color body porcelain were used respectively to make 6 all-porcelain tiles with a thickness of 2mm and a diameter of 12mm. The color was observed and the color difference was measured by a VITA Easyshade colorimeter. Statistical analysis. Results: There was no significant difference between titanium tiles and VITA ordinary tiles. The color difference of Ti-22 titanium tiles measured by colorimeter was 2.53 and the color difference of VITA common porcelain was 1.4. According to statistical analysis, There was significant difference (P <0.05). Conclusion: Titanium porcelain color matching slightly inferior to ordinary porcelain, but can be accepted by the clinic.
