摘要：

背景：研究表明，不同桩核材料对IPS-EmpressⅡ全瓷冠系统美观修复效果有一定程度的影响。
目的：比较IPS-EmpressⅡ全瓷冠在4种不同的桩核材料背景下色彩学方面的差异，为临床选择不同的桩核系统以及应用该全瓷系统提供依据。
方法：选取1颗完整离体上颌中切牙，进行桩道、4种不同材料桩核以及一个IPS-EmpressⅡ全瓷冠的制备，分为4组：镍铬合金桩核组、金合金桩核组、氧化锆桩铸瓷核组、纤维桩树脂核组。采用美能达CM-700d分光测色仪，测试4组不同桩核材料背景下IPS-EmpressⅡ全瓷冠唇面中1/3区域的颜色参数。
结果与结论：4种不同的桩核材料背景下IPS-EmpressⅡ全瓷冠的L*a*b*值的差异有显著性意义。镍铬合金桩核组的色差大于金合金桩核组，均超过临床可接受水平(△E>2)，氧化锆桩铸瓷核组色差大于纤维桩树脂核组，处于临床可接受范围内，但纤维桩树脂核组色差肉眼不能识别其差异(△E<1.5)。在临床应用IPS-EmpressⅡ全瓷冠修复根管治疗后的上前牙时，推荐使用纤维桩树脂核，可以考虑使用全瓷桩核，不建议使用金属桩核。

Abstract:

BACKGROUND: Studies have demonstrated that there are some influences of different post and core materials on the aesthetic effect of IPS-EmpressⅡceramic system.
OBJECTIVE: To compare the color of IPS-EmpressⅡ ceramic system among four kinds of post and core materials and to provide guidance for the clinical use.
METHODS: An intact central incisor was selected from upper jaw. The post path, four kinds of post and core materials, and a crown with IPS-EmpressⅡ ceramic were prepared. There were four groups according to the material: Ni-Cr alloy, golden alloy, ceramic post-and-core, and resin core with fiber-post groups. The CM-700d spectrophotometric tester was used to test the color parameter for the four groups.
RESULTS AND CONCLUSION: There were significant difference of the L*a*b* value in four groups with different post-and-core. The △E value in the Ni-Cr alloy group was larger than in the golden alloy group, beyond the level that could be accepted in clinic (△E > 2). The △E value in the all ceramic post-and-core group was larger than in the resin core with fiber-post group, accepted in clinic, but the color difference could not be identified by the naked eye (△E < 1.5). In combination with IPS-EmpressⅡ crown, resin core with fiber post was suitable for routine use, all ceramic post-and-core could be recommended, but Ni-Cr alloy and golden alloy post-and-core could not be recommended for clinical practice.
