不同树脂粘接剂对渗透陶瓷粘接强度的影响

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Futurabond 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24h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.%Objective To observe and compare the shear bond strength of different composite resin cement systems to glass infiltrated alumina oxide ceramic. Methods 40 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. Results Shear 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. Conclusion A successful bond can be achieved by Panavia F in glass infiltrated alumina oxide ceramic.
