摘要/Abstract

摘要： 目的： 评估摩擦化学法硅涂层对氧化锆陶瓷粘接强度的影响。方法： 将切割烧结后的Lava氧化锆瓷块60件分为6组，每2组分别经喷砂/硅烷偶联剂、喷砂/CoJet Sand/硅烷偶联剂、无处理3种表面处理后，相同表面处理的2组中，每组分别用RelyX Unicem或Panavia F2.0与牙釉质粘接。各组随机抽取5件共30件进行24 h水浴，其余30件进行5000周水热循环，然后进行剪切粘接强度测试。采用SPSS 23.0软件包对数据进行双因素方差分析、Tukey HSD多重比较法及t检验。结果： 喷砂/CoJet/硅烷组的剪切强度均显著高于其他2组（P<0.001）；经老化试验后，喷砂/CoJet/硅烷组使用RelyX Unicem仍保持较高的剪切强度[(21.374±4.433)MPa]，与其他各组相比有显著差异（P<0.001）。结论： 摩擦化学法硅涂层能够有效提高氧化锆的粘接强度及耐久性，表面处理方式与粘接剂之间的相互作用需得到临床关注。

Abstract: PURPOSE: To evaluate the effect of tribochemical silica coating for zirconia bonding. METHODS: Sixty cut and fully sintered Lava frame zirconia blocks were randomly divided into 6 groups and subjected to 3 different surface treatments and 2 kinds of resin cement.The surface treatments were airborne-particle abrasion/silane, airborne-particle abrasion/CoJet Sand (tribochemical silica coating) /silane and no treatment(control), resin cements were RelyX Unicem and Panavia F2.0. Half of the specimens in each group were randomly chosen and stored in 37℃ distilled water for 24h, the others were thermocycled (5℃ and 55℃) for 5000 cycles. All specimens were subjected to shear bond strength(SBS) testing. SBS values were analyzed by two-way ANOVA and t test, and multiple pairwise comparisons were then completed with post hoc Tukey test. Statistical analysis was performed using SPSS23.0 software package for Windows. RESULTS: Airborne-particle abrasion/CoJet sand/silane group resulted in a significantly higher SBS than those in other groups (P<0.001). After thermocycling, the bond strengths in the airborne-particle abrasion/CoJet Sand/silane groups bonded with RelyX Unicem showed no significantly decrease while marked drop appeared in all other groups. CONCLUSIONS: Combination of tribochemical silica coating with silane coupling can effectively enforce the bond strengths of zirconia (Y-TZP). Attention should be paid to the interaction between surface treatments and resin cements.
