摘要: 目的: 探讨组织面遮色处理对氧化锆与树脂间粘接性能的影响。方法: 制作氧化锆试件并随机分为3组:对照组、浸泡染色组、浸泡染色遮色组。每组随机分为2个亚组,分别涂或不涂硅烷耦联剂。测试3组试件接触角;将试件与树脂水门汀粘接,24 h后进行剪切粘接强度测试并观察界面断裂模式。结果: 各组接触角,断裂模式无统计学差异;浸染组粘接强度与对照组无统计学差异,浸染并遮色组粘接强度显著低于对照组及浸染组;各硅烷耦联剂亚组粘接强度显著高于不涂组。结论: 浸泡染色对氧化锆陶瓷与树脂间粘接强度无显著影响;浸染后遮色处理可降低氧化锆陶瓷与树脂间粘接强度;涂布硅烷耦联剂可显著增强氧化锆陶瓷与树脂间粘接强度。

Abstract: Objective: To investigate the effect of masking treatment on the adhesion between zirconia ceramics and resin. Methods: Zirconia specimens were made and randomly divided into 3 groups: control group, immersion dyeing group, and immersion dyeing masking group. Each group was randomly divided into 2 subgroups, with or without silane coupling agent. The contact angles of specimens were tested. The specimens were bonded with the resin cement. The shear bond strength was tested after 24 hours and the interface fracture mode was observed. Results: There was no statistical difference in contact angle and fracture mode between the groups. There was no difference in the bonding strength between the immersion dyeing group and the control group. The bonding strength of the immersion dyeing-masking group was significantly lower than those of other two groups. Subgroups coated with a silane coupling agent had significantly higher bonding strength than those without coating. Conclusion: The immersion dyeing has no significant effect on the bonding strength between zirconia ceramics and resins. The masking treatment after immersion dyeing can reduce the bonding strength between zirconia ceramics and resins. Coating silane coupling agents can significantly enhance the zirconia ceramics and resins bonding strength.
