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.
