摘　　要：目的评价一种自粘接树脂水门汀RelyX^(TM) U_(200)与氧化锆陶瓷粘接的强度和耐久性。方法 90枚氧化锆瓷片(Y-TZP)喷砂处理后分别以"使用自粘接树脂水门汀RelyX^(TM) U_(200)(RU组)"和"氧化锆底涂剂处理+使用传统树脂水门汀RelyX Veneer(ZPRV组,对照组)"两种粘接策略制作Y-TZP/树脂水门汀/光固化复合树脂结构的粘接试件。两组试件分别按照以下三种方法进行处理:37℃水储24 h,30 000次冷热循环下进行人工老化,37℃水储6个月进行人工老化,随后测试试件的剪切粘接强度,分析断裂模式。按照剪切测试同样的两种粘接策略分别制作双瓷层粘接试件(n=10),以去离子水浸泡,电感耦合等离子体质谱(ICP-MS)测试1、7、14、21、30、60和90 d的磷元素释放量。结果两种粘接策略提供了类似的氧化锆陶瓷与树脂间的粘接强度(P=0.841),这一粘接强度在老化处理后均降低(P<0.05),并且老化处理后各组试件的粘接断裂模式所占比例增加。RU组可获得与ZPRV组相等或更高的粘接耐久性。ICP-MS测试仅在Ctr-RU(单纯树脂水门汀RelyX^(TM) U_(200),对照组)、RU和ZPRV中检测到了磷元素的释放,随浸泡时间的延长,磷元素的释放呈现一定的增加。结论 RelyX^(TM) U_(200)树脂水门汀在无需底涂剂处理的条件下用于氧化锆陶瓷粘接可获得较好的粘接强度和粘接耐久性。Objective To evaluate the bonding strength and durability of one type of self-adhesive resin cement RelyXTM U200 bonding to zirconia ceramic. Methods 90 pieces of zirconia ceramic(Y-TZP) plates were sandblasted and randomly divided into 2 groups, bonded with a self-adhesive resin cement RelyXTM U200(RU group) and a conventional resin cement RelyX Veneer combined with zirconia primer(ZPRV group, control group) to produce Y-TZP/resin cement/composite resin adhesive specimens. Then adhesive specimens were randomly divided into 3 subgroups(n=15) to receive different treatment methods: water storage at 37 ℃ for 24 hours, 30000 thermal cycles, and water storage at 37 ℃ for 6 months, followed by shear bond strength test and failure mode analysis. Double-layered Y-TZP adhesive specimens(RU and ZPRV groups) were immersed in deionized water after 1, 7, 14, 21, 30, 60 and 90 days, using inductively coupled plasma mass spectrometry(ICP-MS) to detect the phosphorus release. Results The two bonding strategies achieved similar bond strength between zirconia ceramic and composite resin(P=0.841). After aging, the bond strength decreased(P<0.05) and the proportion of adhesive failure in each group increased. The RU group obtained the same or even higher bonding durability than the ZPRV group. ICP-MS detected the release of phosphorus only in the Ctr-RU(only self-adhesive resin cement RelyXTM U200, control group), RU and ZPRV groups, and the release of phosphorus increased with the prolongation of soaking time. Conclusion RelyXTM U200 resin cement can achieve the desired bond strength and bond durability for zirconia ceramics bonding without primer pre-treatment.
