摘要: 目的 评价磷酸酯单体MDP在几种不同的溶剂环境中对提高氧化锆陶瓷与树脂粘接效果的影响。 方法 配置MDP的乙醇、丙酮和乙醇/丙酮(1∶1)溶液作为实验性底涂剂,对比这几种底涂剂处理氧化锆陶瓷后与树脂的粘接强度,测试以不应用任何底涂剂作为阴性对照组,以应用市场常用包含MDP的底涂剂产品作为阳性对照组。使用X线光电子能谱分析检测实验性底涂剂处理氧化锆陶瓷后表面新形成的化学键。 结果 未应用底涂剂组显示了最低的粘接强度值,当前实验中的3种溶剂的底涂剂显示了较高的粘接强度值,但各组间并无统计学差别。X线光电子能谱分析在几种实验性底涂剂处理的氧化锆表面均检测出“-P-O-Zr”键。 结论 以丙酮、乙醇或两者混合液作为溶剂时MDP均能提高氧化锆陶瓷与树脂的粘接强度。

Abstract: Objective To evaluate the influence of the phosphate eater monomer 10metacryloxydecyl dihydrogen phosphate (MDP) on resin bonding of yttriastabilized tetragonal zirconia polycrystals (YTZP), performed in various solvent environments. Methods Ethanol, acetone and ethanol/acetone(1∶1) solution containing MDP were prepared as experimental primers respectively. Shear bond strength testing was performed to compare the efficacy of the three kinds of experimental primers in improving resinzirconia bond strength. The group conditioned with no primers was taken as the negative control and another with a commercially available MDPcontaining primer served as the positive control. Xray photoelectron spectroscopy (XPS)was used to investigate the formation of chemical bond on the surface of YTZP treated with the three experimental primers containing MDP. Results The negative control group presented the lowest SBS, whereas the three groups conditioned with experimental primers showed higher values, which were not significantly different from one another (P>0.05). The XPS spectra analysis detected POZr bond on the surface of YTZP treated with the MDP ethanol solution or acetone solution. Conclusion No matter ethanol, acetone, or the mixing of the two as the solvent, the MDP can improve the resin bond strength of zirconia. 
