中文摘要:
      目的:评价2种含磷酸酯单体的底涂剂处理的Y?TZP陶瓷与树脂的粘接及其耐水解性。方法:80枚氧化锆(Y?TZP)瓷片随机分为4组进行不同的表面处理:氧化铝喷喷砂;氧化铝喷砂后以氧化锆底涂剂Z?Prime Plus或Clearfil Ceramic Prime处理;摩擦化学法硅涂层后以硅烷处理。使用树脂水门汀制作粘接试件测试其剪切粘接强度。Y?TZP瓷片表面分别经过2种底涂剂处理后以X射线光电子能谱分析(XPS)检测其表面化学键变化。采用电感耦合等离子体制谱(ICP?MS)测试Y?TZP/树脂粘接界面的磷元素释放量。结果:老化前,与阴性对照组相比,2种含MDP的底涂剂处理均能提高短期粘接强度值,但硅涂层处理组的粘接强度最高。老化后,硅涂层处理组较老化前未有明显变化;喷砂及2种含MDP底涂剂处理组的粘接强度值显著下降(P < 0.05)。XPS在Y?TZP陶瓷使用2种含MDP底涂剂处理后均检测出“?P?O?Zr”键。ICP?MS测试在使用含MDP底涂剂处理的粘接试件的浸泡液中检测到磷元素的释放。结论:水会负面影响磷酸酯单体介导的氧化锆与树脂间的粘接。
英文摘要:
      Objective:This study aimed to evaluate the durability of resin bonding to an yttria?stabilized tetragonal zirconia polycrystals(Y?TZP)using two different primers containing phosphate ester monomer [10?methacryloyloxydecyl dihydrogen phosphate(MDP)]. Methods:A total of 80 zirconia plates were prepared and assigned to 4 groups to build bonded specimens according to surface treatments(sandblasted with alumina particles;sandblasted with alumina particles followed by application of Z?Prime Plus or Clearfil Ceramic Primer;tribochemical silica coating followed by application of silane). Bonded specimens were built using resin luting cement and tested for shear bond strength(SBS). X?ray photoelectron(XPS)was used to investigate the formation of chemical bond on the surface of Y?TZP after conditioned with two types of MDP containing primers. Release of the element phosphorus from MDP?mediated Y?TZP/resin?bonded interfaces were evaluated via inductively coupled plasma?mass spectrometry(ICP?MS). Results:The two types of MDP containing primers increased the SBS in short time,compared to negative control group,the tribochemical silica coating group obtained the highest SBS. After thermocycling,no statistical difference was observed in tribochemical silica coating group,but SBS decreased significantly in groups sandblasted and conditioned with two types of MDP containing primers(P < 0.05). XPS analysis detected ?P?O?Zr bond on the surface of Y?TZP conditioned with MDP?containing primers. Phosphorus was detected by ICP?MS from the solutions used for immersed the Y?TZP/resin?bonded specimens. Conclusion:Water negatively affects bonding between zirconia and resin mediated by MDP?containing primers.
