摘要/Abstract

摘要： 目的评价氧化锆陶瓷经几种表面处理后在不同强度的人工老化实验条件下的粘接耐久性。方法制备4组氧化锆陶瓷/树脂粘接试件128个，各组试件氧化锆陶瓷按照以下方式处理并使用不同种类的树脂水门汀。组A，摩擦化学法硅涂层+硅烷偶联剂；组B，氧化铝喷砂；组C，氧化铝喷砂+应用氧化锆涂底剂Z-Prime Plus；组D，氧化铝喷砂+应用氧化锆涂底剂Z-Prime Plus。组A和C使用传统Bis-GMA基光固化树脂水门汀，组B和D使用自粘接树脂水门汀。各实验组再分为4个亚组接受不同的人工老化。不接受人工老化（a），水储40 d（b）；冷热循环1 200次；水储40 d后冷热循环12 000次。测试各组剪切粘接强度值并进行统计学分析。摩擦化学法硅涂层和氧化铝喷砂的氧化锆陶瓷表面以扫描电镜观察并进行能谱分析。结果不论接受或不接受人工老化，4种表面处理间对氧化锆陶瓷的粘接强度值影响无统计学差异。各实验组单独来看，仅有人工老化方式d时粘接强度值都出现了下降，差别具有统计学意义。结论不同人工老化强度对氧化锆陶瓷粘接强度的影响不同。

Abstract: Objective To evaluate the effects of artificial aging on bond durability of zirconia treated with different methods. Methods 128 zirconia/composite resin bonding specimens for 4groups were prepared. Surface conditioning and resin cement were used by groups: A=tribochemical silica coating + silane + Bis-GMA based resin cement; B=alumina sandblasting + self-adhesive resin cement; C=alumina sandblasting + zirconia primer Z-Prime Plus+ Bis-GMA based resin cement; D= alumina sandblasting + zirconia primer Z-Prime Plus+ self-adhesive resin cement. Each group was divided into 4 subgroups to receive different artificial aging as no aging, water storage for 40 days, thermal cycling for 1200 times, and thermal cycling for 12000 times after water storage for 40 days. The shear bond strength of each specimen was tested. The zirconia surface treated with tribochemical silica coating or alumina sandblasting was observed by a scanning electron microscopy and electron spectroscopy analysis was done. Results No statistically significant difference was found among the 4 groups whether accepting artificial aging or not. In each group, only the subgroup d showed significantly lower bond strength values and the difference was statistically significant. Conclusion Different artificial aging methods have different effects on bonding strength of zirconia.
