This study attempted to bond glass-ionomer and zinc phosphate cements to a dental ceramic with the aid of a coupling agent and appropriate surface preparation. Four luting agents were shear tested after thermocycling: a glass-ionomer cement with three titanate coupling agents, three zircoaluminate coupling agents, and a silane coupling agent; a light-activated glass-ionomer cement with a silane coupling agent; a zinc phosphate with a titanate coupling agent; and the manufacturer's resin/silane as control. The light-activated glass-ionomer cement/silane coupling agent had the highest mean strength (3.8 MPa) followed by the control (3.7 MPa) and glass-ionomer/carboxy zircoaluminate (2.4 MPa). These measures were significantly (P < .05) higher than those of glass-ionomer/silane, zinc phosphate, and other lower ranking groups. Light-activated glass-ionomer cement was successfully bonded to dental ceramics. Carboxy zircoaluminate showed good results for bonding conventional glass-ionomer cement.
本研究试图借助偶联剂和适当的表面处理,将玻璃离子水门汀和磷酸锌水门汀粘结到牙科陶瓷上。四种粘结剂在热循环后进行了剪切测试:一种含三种钛酸酯偶联剂、三种锆铝酸酯偶联剂和一种硅烷偶联剂的玻璃离子水门汀;一种含硅烷偶联剂的光固化玻璃离子水门汀;一种含钛酸酯偶联剂的磷酸锌水门汀;以及作为对照的制造商的树脂/硅烷。光固化玻璃离子水门汀/硅烷偶联剂的平均强度最高(3.8MPa),其次是对照组(3.7MPa)和玻璃离子水门汀/羧基锆铝酸酯(2.4MPa)。这些测量值显著(P<.05)高于玻璃离子水门汀/硅烷、磷酸锌和其他排名较低组的值。光固化玻璃离子水门汀成功地粘结到牙科陶瓷上。羧基锆铝酸酯在粘结传统玻璃离子水门汀方面显示出良好的效果。
