目标.通过二氧化硅涂层、随后的硅烷化和三种一瓶通用粘合剂（无论是否使用氧化锆底漆进行预先调节），评估树脂水泥与氧化钇稳定四方氧化锆多晶（Y-TZP）的粘合。方法。Y-TZP试样（n = 160）通过摩擦化学二氧化硅涂层和硅烷化（CS）或氧化铝喷砂处理，用以下含MDP的粘合剂或底漆之一进行处理：Z-Prime Plus（TM）（氧化锆底漆，ZP）、Single Bond Universal（TM）（SU）、Clearfil Universal Bond（TM）（CU）或All-Bond Universal（TM）（Au）。此外，一些样本（ZPSU，ZPCU和ZPAU）接受Z-Prime Plus（TM），然后使用三种粘合剂之一。在24小时水储存和“老化”（20，000次热循环加上另外40天水储存）后，测量剪切粘结强度（SBS）。采用傅里叶变换红外光谱（FTIR）和X射线光电子能谱（XPS）表征底漆/粘合剂与氧化锆之间的化学键。通过热力学计算考察了MDP-氧化锆化学键和SiO2-硅烷化学键之间的水解稳定性。CS和ZPCU组的SBS高于其他六组。ZP、SU和ZPSU之间，或ZP、Au和ZPAU之间无显著性成对差异。除CS和ZPCU外，老化导致所有组的SBS显著降低。表面处理和老化之间没有统计学显著的相互作用。XPS测定了MDP和氧化锆之间的化学键。FTIR显示所有底漆和/或粘合剂基团的特征磷酸盐峰的类似位移。热力学计算结果表明，SiO2-硅烷体系的平衡常数远大于MDP-四方相氧化锆体系的平衡常数。氧化铝喷砂后应用一瓶通用粘合剂是一种替代摩擦化学二氧化硅涂层与硅烷化粘接氧化锆，而树脂和Y-TZP之间的粘接更容易水解时，氧化锆底漆或一瓶通用粘合剂使用。(C)2015年牙科材料学院。由Elsevier Ltd.出版。保留所有权利。
Objectives. To evaluate the bonding of resin-cement to yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) via silica coating followed by silanization, and three one-bottle universal adhesives, with or without prior conditioning using a zirconia primer.Methods. Y-TZP specimens (n = 160) were conditioned by tribochemical silica coating and silanization (CS), or alumina sandblasting with one of the following MDP containing adhesives or primers: Z-Prime Plus (TM) (zirconia primer, ZP), Single Bond Universal (TM) (SU), Clearfil Universal Bond (TM) (CU) or All-Bond Universal (TM) (AU). Additionally, some specimens (ZPSU, ZPCU and ZPAU) received Z-Prime Plus (TM) followed by one of the three adhesives. After 24 h water storage and "aging" (20,000 thermocycles plus additional 40-day water storage), shear bond strength (SBS) was measured. Fourier-transform infrared spectroscopy (FTIR) and Xray Photoelectron Spectroscopy (XPS) were employed for characterization of the chemical bonds between the primer/adhesives and the zirconia. Thermodynamic calculations were used to examine the hydrolytic stability between the MDP-zirconia chemical bonds and the SiO2-silane chemical bonds.Results. The CS and ZPCU groups showed higher SBS than the other six groups. There were no significant pairwise differences amongst ZP, SU and ZPSU, or amongst ZP, AU and ZPAU. Aging led to significantly decreased SBS for all groups except CS and ZPCU. There was no statistically significant interaction between surface treatment and aging. XPS determined the chemical bonds between MDP and zirconia. FTIR showed similar shifts in characteristic phosphate peaks for all the primer and/or adhesive groups. Result of thermodynamic calculation showed that equilibrium constant of SiO2-silane system is much larger than the one of MDP-tetragonal phase zirconia system.Significance. The application of one-bottle universal adhesives after alumina sandblasting is an alternative to tribochemical silica coating with silanization for bonding to zirconia, while bonding between resin and Y-TZP is more susceptible to hydrolysis when zirconia primer or one-bottle universal adhesive is used.
