摘要/Abstract

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10 mm×10 mm×2 mm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24 h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。

Abstract: 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 treatmentmethods: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 Scotchbond^TM 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.
