Etching or roughening the surface of glass ionomer cement before use of composite resins and bond agents produces bond strengths comparable to the bond strength between glass ionomers and dentin. Bond failure at such surfaces occurs within the glass ionomer. Adequate washing with water after acid etching the glass ionomer is essential to obtain optimal bond strength. Apparently, some combinations of ionomer cements and resins are more effective than are others in providing a good bond in the "sandwich technique".
在使用复合树脂和粘结剂之前对玻璃离子水门汀表面进行蚀刻或粗糙化处理，可产生与玻璃离子水门汀和牙本质之间的粘结强度相当的粘结强度。在这种表面发生的粘结失败发生在玻璃离子水门汀内部。对玻璃离子水门汀进行酸蚀后用水充分冲洗对于获得最佳粘结强度至关重要。显然，在“三明治技术”中，某些离子水门汀和树脂的组合在提供良好粘结方面比其他组合更有效。
