中文摘要
目的 研究纳米氢氧化锆在氧化锆陶瓷表面形成碱性涂层后对10-甲基丙烯酰氧癸二氢磷酸酯（MDP）与氧化锆陶瓷粘接强度的影响。方法 制作氧化钇稳定四方相氧化锆（Y-TZP）瓷片140枚,氧化铝喷砂后对其表面进行不同的处理,制作粘接试件并测试剪切粘接强度。以X线光电子能谱（XPS）检测Y-TZP陶瓷表面依次经过纳米氢氧化锆涂层和含有MDP的底涂剂处理后的化学键变化。结果 老化前,与对照组相比,两种碱性涂层均能提高短期粘接强度值,纳米氢氧化锆涂层增强效果更显著。老化后,各组粘接强度值差异无统计学意义,但较老化前均显著降低（P<0.05）。XPS在制备纳米氢氧化锆涂层的Y-TZP瓷片表面检测到-OH键,在制备纳米氢氧化锆涂层的Y-TZP陶瓷应用含有MDP的底涂剂处理后检测出-P-O-Zr键。结论 在氧化锆陶瓷表面制备碱性涂层能够使MDP提高氧化锆陶瓷粘接强度。
英文摘要
ObjectiveThis study evaluated the influence of alkaline coating of nano-zirconium hydroxide on resin bonding of 10-methacryloxy decyldihydrogen phosphate (MDP)-conditioned zirconia.MethodsA total of 140 yttria-stabilized tetragonal zirconia polycrystals (Y-TZP) plates were prepared and sandblasted with alumina particles, and then subjected to different surface treatment. Resin bonding specimens were prepared with a MDP-free resin cement and tested for shear bond strength (SBS). X-ray photoelectron spectroscopy (XPS) was used to investigate the formation of chemical bond on the surface of Y-TZP treated successively with nano-zirconium hydroxide coating and MDP containing primer.ResultsThe two alkaline coatings increased the 24 h SBS compared to control groups, and groups using nano-zirconium hydroxide coating yielded higher SBS. After thermocycling, no statistical difference was observed between groups, but SBS decreased significantly compared to the 24 h SBS (P<0 .05). xps analysis detected -oh bond on the surface of y-tzp treated with nano-zirconium hydro-xide coating, and -p-o-zr bond was detected on the surface of y-tzp treated with nano-zirconium hydroxide coating and mdp-containing primer.ConclusionAlkaline coatings improved the bonding of resin to zirconia conditioned with MDP-containing primers.
