摘要：

背景：目前对适合应用于氧化锆陶瓷的表面处理方式仍有争论。有学者认为传统硅烷化处理无法提高氧化锆陶瓷的黏结强度，但也有文献报道经硅烷化处理或喷砂处理之后进行硅烷化处理均可提高氧化锆陶瓷的黏结强度。
目的：测试不同表面处理后氧化锆陶瓷与树脂黏结剂之间的黏结强度，探讨适合口腔氧化锆陶瓷黏结的表面处理方法。
方法：将氧化锆陶瓷胚体切割成15 mm×10 mm×3 mm的试件50个，烧结后根据对其表面的处理方式不同分为以下5组：对照组(不处理)、硅烷偶联剂组、喷砂组、喷砂+硅烷偶联剂组、喷砂+硅溶胶+硅烷偶联剂组。将所有试件与树脂黏结剂黏结，形成剪切测试样本，于疲劳试验机上测试其剪切黏结强度，观察所有测试后样本的破坏模式。
结果与结论：4个实验组的剪切黏结强度值均明显高于对照组(P < 0.05)，喷砂+硅烷偶联剂组剪切强度值最高。除喷砂组与喷砂+硅溶胶+硅烷偶联剂组、喷砂+硅烷偶联剂组与喷砂+硅溶胶+硅烷偶联剂组间比较差异无显著性意义(P > 0.05)外，其余每两组间比较差异均有显著性意义(P < 0.05)。说明喷砂和硅烷偶联剂均能够提高氧化锆陶瓷与树脂黏结剂的黏结强度；喷砂联合硅烷偶联剂是最适合牙科氧化锆陶瓷黏结的表面处理方法。硅溶胶未明显影响氧化锆陶瓷与树脂黏结剂的黏结强度。

Abstract:

BACKGROUND: At present the surface treatment of zirconia ceramics remains controversial. Some scholars believe that the traditional silanization treatment can not improve the bond strength of zirconia ceramics, while it has reported that silanization treatment or treatment after sandblast can improve the bond strength of zirconia ceramics.
OBJECTIVE: To evaluate the effect of different surface treatments on bond strength of zirconia ceramics to resin cement, and to find proper surface treatment for bonding oral zirconia ceramic.
METHODS: According to surface treatment, 50 zirconia ceramic sheets (15 mm×10 mm×3 mm) after sintering were divided into five groups: control group (no treatment), silane coupling agent group, sandblast group, sandblast plus silane coupling agent group, sandblast plus silica coating and silane coupling agent group. All samples were bonded to resin cement and subjected to a shear bond strength test in a fatigue testing machine. Fracture mode of each sample tested was observed.
RESULTS AND CONCLUSION: Shear bond strength values of four experimental groups was significantly increased compared with control group (P < 0.05), reached the peak in sandblast plus silane coupling agent group. Except for sandblast group and sandblast plus silica coating and silane coupling agent group, sandblast plus silane coupling agent group and sandblast plus silica coating and silane coupling agent group (P > 0.05), the significant differences were showed between every two groups (P < 0.05). Sandblast and silane coupling agent can effectively enhance the shear bond strength of zirconia ceramic to resin cement. Sandblast combined with silane coupling agent is the most proper surface treatment for bonding zirconia ceramic. Silica sol cannot affect bond strength of zirconia ceramic to resin cement.
