摘　　要：目的:探讨几种表面处理方法对氧化锆修复体粘接强度的影响,为提高氧化锆修复体的粘接力提供依据。方法:加工10mm×10mm×2mm钇稳定氧化锆瓷坯60件,根据表面处理方法不同将试件分成喷砂组、硅涂层组、Z-PRIME Plus组、喷砂+Z-PRIME Plus组、喷砂+硅涂层组和硅涂层胶+Z-PRIME Plus组,每组10件。使用通用型粘接剂Scotchbond^(TM) Universal制作氧化锆-树脂粘接样本,在37℃水浴中储存24h后采用万能力学试验机测试其剪切强度,体视显微镜记录样品断裂模式,各组断裂样品随机抽取1件,在扫描电子显微镜下观察其表面形貌。结果:Z-PRIME Plus组试件所测得的剪切强度明显高于其他组(P<0.05)。断裂模式观察,粘接破坏主要出现在喷砂、硅涂层、喷砂+硅涂层和硅涂层+Z-PRIME Plus组试件中。喷砂+Z-PRIME Plus组试件混合破坏4例,喷砂+硅涂层组试件混合破坏8例;各组试件均未出现内聚破坏。扫描电镜下观察,喷砂、Z-PRIME Plus和喷砂+Z-PRIME Plus组试件断裂面发生在粘接剂-氧化锆界面,硅涂层、硅涂层+Z-PRIME Plus组试件断裂面发生在硅涂层-氧化锆界面,喷砂+硅涂层组试件断裂面部分发生在硅涂层-粘接剂界面。结论:Z-PRIME Plus用于氧化锆表面预处理可以明显提高其与树脂的粘接强度。Objective：To evaluate the effects of several kinds of surface treatment methods on the bond strength of zirconia prosthesis,and to provide references for improving the bond strength of zirconia prosthesis.Methods：Sixty zirconia blocks（10 mm×10 mm×2 mm） were divided into 6 groups according to the surface treatment methods：sandblasting,silica coating,Z-PRIME Plus,sandblasting＋Z-PRIME Plus,sandblasting＋silica coating,and silica coating＋Z-PRIME Plus groups.The zirconia-resin specimens were fabricated using ScotchbondTM Universal;shear bond test was performed to detect the shear bond strength after treated with water storage（37℃） for 24 h by universal mechanical testing mechine;the fracture types were observed by stereoscopic microscope.One fracture specimen was randomly chosen from each group,and the morphology of the specimen was examined under scanning electron microscope.Results：The shear bond strength of the specimen in Z-PRIME Plus group was higher than those in the other groups（P〈0.05）.The adhesive failure was predominantly observed in sandblasting,silica coating,sandblasting＋silica coating and silica coating＋Z-PRIME Plus groups.There were 4 cases of mixed failure in Z-PRIME Plus group and there were 8 cases of mixed failure in sandblasting＋Z-PRIME group.No cohesive failure was observed in all the groups.The scanning electron microscope results showed that the fracture surface occurred on the resin-zirconia interface of the specimens in sandblasting group,Z-PRIME Plus group,and sandblasting＋Z-PRIME Plus group.The silica-zirconia fracture of specimens occurred in silica coating group and silica coating＋Z-PRIME Plus group.The silica-resin interface fracture of specimens partially occurred in sandblasting＋silica coating group.Conclusion：The application of Z-PRIME Plus can significantly improve the bond strength between zirconia and resin.
