摘要： 目的　评价溶胶凝胶自组装法硅涂层对氧化锆陶瓷与树脂短期粘结强度的影响。方法　加工56 个氧化锆瓷块并随机分为4 组，分别对粘结面进行以下处理：A组：硅烷偶联剂；B组：溶胶凝胶浸涂1层硅涂层+硅烷偶联剂；C组：溶胶凝胶自组装2层硅涂层+硅烷偶联剂；D组：溶胶凝胶自组装3层硅涂层+硅烷偶联剂。制作56 枚光固化复合树脂圆柱并用树脂水门汀粘结于预处理后的氧化锆瓷块上，水浴24 h 后测试剪切粘结强度。以扫描电镜和表面能谱分析对不同表面处理的氧化锆进行表征分析，体视显微镜记录样品断裂模式。结果　A组到D组各组剪切粘结强度值分别为（3.05±0.26）MPa，（6.83±0.33）MPa、（10.51±0.58）MPa和（7.72±0.35）MPa。除B组和D组无统计学差异外，其余各组之间均具有统计学意义(P=0.000)。其中溶胶凝胶自组装2层硅涂层获得的剪切粘结强度值最大。结论　溶胶凝胶自组装法硅涂层可以提高氧化锆陶瓷表面粘结强度，其中溶胶凝胶自组装2层硅涂层组的效果最好。

Abstract: Objective　To evaluate the effect of silicon coating prepared by sol-gel self-assembling on instant bond strength of zirconia ceramic and resin. Methods　56 zirconia ceramic slices were obtained and randomly divided into 4 groups based on the surface treatment to be applied: groupA: silane couple agent; group B: sol-gel impregnated with 1 layer of silicon coating and silane couple agent; group C: sol-gel self-assembly 2 layer silicon coating + silane coupling agent; group D: sol-gel self-assembly 3 layer silicon coating and silane couple agent. 56 photo-cure composite resin columns were prepared and bonded on the zirconia ceramic by resin cement. Bonded specimens received shear bond strength testing after 24-hour water storage. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) were used to characterize the zirconia of different surface treatments, and the sample fracture mode was recorded by the stereoscopic microscopy. Results　The shear bond strength values of group A, B, C, D were respectively (3.05±0.26) MPa, (6.83 ±0.33) MPa, (10.51 ± 0.58) MPa and (7.72±0.35) MPa. There was no statistical difference between group B and group D, while all the other groups were statistically significant (P=0.000).The shear bond strength obtained by self-assembly of two silicon coatings was the largest. Conclusions　Sol-gel self-assembled silicon coating can improve the adhesion strength of zirconia ceramics. The result of sol-gel self-assembling 2-layer silicon coating group is the best.
