The aim of this study was to evaluate the influence of multimode MDP-based primers and different application protocols on the bond strength of a representative resin cement to an yttrium stabilized tetragonal zirconia (Y-TZP) ceramic.
The occlusal dentin from 60 human molars was exposed. The teeth and zirconia cylinders (N = 60) (3 mm of diameter; 4 mm of height) were divided into six groups (n = 10) according to the ceramic surface conditioning: (1) air abraded with SiO particles; (2) Z-Prime Plus; (3) air abraded with SiO particles + Z-Prime Plus; (4) air abraded with SiO particles + All-Bond Universal; (5) air abraded with SiO particles + ScotchBond Universal Adhesive; and (6) untreated zirconia. The luting agent (Duo-Link cement) was applied on the treated dentin surface. Specimens were stored in water (37°C, 24 h) and tested in shear bond strength. Data were statistically analyzed using 2-way ANOVA and Post hoc Tukey tests ( = 0.05).
Significant effects of ceramic conditioning were found (p < 0.0001). The specimens sandblasted with silica particles followed by the application of Z-Prime Plus or All-Bond Universal presented greater bond strength values. For the untreated zirconia, several specimens failed prematurely prior to testing.
Sandblasting with silica particles combined with Z-Prime Plus increased the bond strength.
本研究旨在评估基于多模态 MDP 的引物和不同应用方案对代表性树脂水泥与钇稳定四方氧化锆（Y-TZP）陶瓷之间粘结强度的影响。
暴露 60 个人类磨牙的牙本质。将牙齿和氧化锆圆柱体（N = 60）（直径 3mm，高度 4mm）根据陶瓷表面处理情况分为六组（n = 10）：（1）用 SiO2 颗粒喷砂；（2）Z-Prime Plus；（3）SiO2 颗粒喷砂+Z-Prime Plus；（4）SiO2 颗粒喷砂+All-Bond Universal；（5）SiO2 颗粒喷砂+ScotchBond Universal 粘合剂；（6）未处理的氧化锆。将粘结剂（Duo-Link 水泥）涂于处理后的牙本质表面。将样本储存在水中（37°C，24h）并进行剪切粘结强度测试。使用 2 因素方差分析和事后 Tukey 检验对数据进行统计学分析（=0.05）。
发现陶瓷处理有显著影响（p < 0.0001）。用硅砂喷砂后再应用 Z-Prime Plus 或 All-Bond Universal 的试件具有更大的粘结强度值。对于未处理的氧化锆，在测试前有几个试件提前发生了过早失效。
硅砂喷砂结合 Z-Prime Plus 可提高粘结强度。
