| 摘 要： | 目的研究不同材料桩核对IPS- Empress 2全瓷冠不同部位颜色的影响规律。方法制作全瓷桩核、氧化锆桩树脂核、金合金桩核、镀金镍铬合金桩核和镍铬合金桩核各3个，用PR- 650光谱扫描色度仪测量不同桩核背景下IPS- Empress 2全瓷冠唇面切1/3、中1/3和颈1/3的L*、a*、b*颜色参数，研究不同材料桩核对全瓷冠颜色的影响。结果全瓷桩核和镀金镍铬合金桩核背景的L*、a*、b*值均高于其他桩核背景，氧化锆桩树脂核背景的L*、a*值较高，b*值较低，金合金桩核背景的L*、a*、b*值较低，镍铬合金背景的L*、a*、b*值最低。结论应用IPS- Empress2全瓷冠修复根管治疗后的上前牙时，推荐使用全瓷桩核和氧化锆桩树脂核，也可以考虑使用镀金镍铬合金桩核或金合金桩核，不推荐使用镍铬合金桩核。

| Abstract: | Objective To evaluate the influence of different types of posts and cores on the final color of the IPS-Emperss 2 crown. Methods Five types of posts and cores(Cerapost with Empress cosmo, Cerapost with composite resin, gilded Ni-Cr alloy, gold alloy and Ni-Cr alloy) were made. The shifts in color of three points of IPS-Empress 2 crown surface(cervical, middle and incisal) with different posts and cores was measured with a spectroradiometer(PR-650). Results The L* a* b* values of zirconium oxide and gilded Ni-Cr alloy posts and cores with ceramic crown were the highest. The L* a* values of zirconium oxide posts composite cores were higher while the b* values were lower. The L* a* b* values of Ni-Cr alloy were lower than that of gold alloy and were the lowest. Conclusion In combination with IPS-Empress 2 crown, zirconium oxide posts are suitable for routine use in the anterior dentition, and gilded Ni-Cr alloy and gold alloy posts and cores can be recommended for clinical practice. Ni-Cr alloy posts and cores can not be recommended for clinical practice. |
