摘要/Abstract

摘要： 目的: 通过体外研究热碱溶液（20%NaOH溶液）处理氧化锆陶瓷表面,探讨处理后的氧化锆陶瓷与树脂水门汀粘接强度的变化。方法: 制作18块氧化锆陶瓷试件块,按相同方法打磨抛光后随机分为3组,A组用热碱溶液（20%NaOH）处理（n=6）,B组用110 μm直径的氧化铝颗粒喷砂处理（n=6）,C组为空白对照组（n=6）。利用原子力显微镜测量试件表面粗糙度,扫描出氧化锆的表面形貌图,制作陶瓷-树脂粘接试件,水储24 h后进行剪切粘接强度（SBS）测试,并对粘接界面进行观察,得出试件的破坏形式。采用SPSS20.0软件包对数据进行统计学处理。结果: 粗糙度B组>A组>C组,剪切强度B组>A组>C组。结论: 在180℃条件下,通过20%NaOH溶液处理氧化锆陶瓷,氧化锆陶瓷与树脂水门汀之间的粘接强度发生改变,热碱溶液处理优于不处理,但不如喷砂处理。

Abstract: PURPOSE: In this experiment, we applied hot alkaline solution (20%NaOH solutions) to treat the surfaces of zirconia ceramics in vitro, then evaluated the changes of bond strength of zirconia ceramics and resin cement. METHODS: Eighteen pieces of zirconia ceramic specimens were made, using the same method of grinding and polishing, and then randomly divided them into 3 groups: group A with hot alkali solution treatment (20%NaOH) (n=6), group B underwent sand blasting with a diameter of 110 μm alumina particles (n=6), group C was as the control group. Atomic force microscope was used to measure the roughness of the surface of the specimens, and the zirconia surfaces were scanned to get topography maps, then made them into ceramic/resin-bonded specimens. After 24 h of water reservoir processing, shearing bonding strength (SBS) test was conducted and their bond interfaces were observed to investigate the lesions of different degree in these specimens. The data were analyzed with SPSS20.0 software package. RESULTS: Surface roughness was group B> group A > group C, SBS was group B>group A>group C. CONCLUSIONS: Under the condition of 180℃, bonding strength between zirconia and resin cement after treatment with 20% NaOH solution was significantly higher than without any treatment, but lower than sand blasting treatment.
