摘要： 目的:探讨3种树脂粘接剂对氧化锆全瓷修复体和IPS e.max Press铸瓷颜色稳定性的影响。方法:氧化锆全瓷修复体和铸瓷试件各45个,随机分为A-F共6组。A、B、C组均为氧化锆全瓷试件,分别采用FujiCEM、RelyX Unicem和RelyX Veneer树脂粘贴;D、E、F组均为铸瓷试件,分别采用FujiCEM、RelyX Unicem和RelyX Veneer树脂粘贴。Shadepilot 数字比色仪测量人工唾液浸泡前(T0)、浸泡1个月(T1)、3个月(T2)、6个月(T3)和9个月(T4)时的光学值和色差值。结果:T0-T4各时间点,A、B、C组以及D、E、F组的L*、a*、b*和△E值比较差异均有统计学意义(P＜0.05)。T1-T4时间点,A组△E值大于B、C组(P＜0.05),D组△E值大于E、F组(P＜0.05)。为期9个月的实验期间,A、B、C组以及E、F组均未出现人眼可辨别的颜色改变,D组在T3点(6个月)时出现了人眼可辨别的颜色改变,在T4点(9个月)时颜色改变进一步加大。结论:与RelyX Unicem和RelyX Veneer树脂粘接剂比较,FujiCEM树脂对颜色稳定性的影响最大,尤其是对铸瓷试件颜色稳定性影响最大。

Abstract: Objective: To investigate the effect of three resin adhesives on the color stability of IPS E.Max press cast porcelain and zirconia all-ceramic restorations. Methods: A total of 45 zirconia all-ceramic specimens and 45 cast-ceramic specimens were prepared and randomly divided into A-F groups, with 15 specimens in each group. Zirconia all-ceramic specimens in groups A, B, and C were bonded with FujiCEM, RelyX Unicem, and RelyX Veneer resins, respectively. Cast-ceramic specimens in group D, E, and F were bonded with FujiCEM, RelyX Unicem, and RelyX Veneer resins, respectively. Shadepilot digital colorimeter was used to measure the optical value (L, a, b) before (T0), 1 month (T1), 3 months (T2), 6 months (T3), and 9 months (T4) after immersion, respectively. The color difference (△E) was calculated. Results: At T0-T4 time points, there were significant differences in L*, a*, b*, and △E values between group A, B, C and D, E, F (P<0.05). At T1-T4 time points, the value of △E in group A was higher than that in group B and C (P<0.05), and the value of △E in group D was higher than that in group E and F (P<0.05). During the nine-month experiment, no discernible color changes were observed in group A, B, C, E and F. In group D, discernible color changes were observed at T3 (6 months) time point and further increased at T4 (9 months) time point. Conclusion: Compared with Relyx Unicem and Relyx, Fujicem has the greatest influence on color stability, especially on the color stability of cast-ceramic.
