[摘要]目的观察比较不同树脂粘接剂对氧化铝渗透陶瓷粘接剪切强度的效果。方法选择无龋坏的人离体磨牙40颗，处理后随机分为4组，每组10件。A组用Solobond Plus粘接剂+Bifix QM粘接剂，B组用Fu-turabond DC粘接剂+Bifix QM粘接剂，C组用Bifix SE自酸蚀树脂粘接剂，D组用Panavia F双重聚合型粘接材料。所有样本在37℃蒸馏水中储存24 h后进行测试，记录剪切强度值，用SAS 6.12统计软件对结果进行单因素方差分析。结果Panavia F双重聚合型粘接材料组的剪切强度显著高于其他3组(P<0.01)，Bifix SE自酸蚀树脂粘接剂组的剪切强度最小。结论Panavia F双重聚合型粘接材料用于氧化铝渗透陶瓷可获得较好的粘接效果，值得在临床上推广。

[Abstract]ObjectiveTo observe and compare the shear bond strength of different composite resin cement systems to glass infiltrated alumina oxide ceramic. Methods40 healthy non-carious human molars were selected in the study. The samples were divided into four groups, 10 pieces for each group, including group A(Solobond Plus+Bifix QM), group B(Futurabond DC+Bifix QM), group C(Bifix SE), and group D(Panavia F). All specimens were stored in water at 37°C for 24 hours. The shear bond strength of four different bonding systems to dentin was tested respectively. The data were statistically analyzed by ANOVA with SAS 6.12. ResultsShear bond strength of Panavia F was significantly higher than that of other three groups(P<0.01), and the shear bond strength of Bifix SE was much lower than other groups. ConclusionA successful bond can be achieved by Panavia F in glass infiltrated alumina oxide ceramic.

玻璃渗透氧化铝陶瓷(glass infiltrated alumina oxide ceramic)简称渗透陶瓷，具有高韧性、高强度、耐化学腐蚀且生物相容性好的优点，在口腔陶瓷材料中备受关注，并被越来越广泛地应用于全瓷修复中。但由于渗透陶瓷的化学组成和结构不同于常规陶瓷，所以在临床上，常规陶瓷的粘接技术用于渗透陶瓷均难以获得牢固的粘接效果[1]。
因此，本研究比较了不同树脂粘接剂对渗透陶瓷的粘接效果，以期为临床上渗透陶瓷修复体粘接剂的选择提供参考。
