目前,BIS-GMA树脂(双酚A和甲基丙烯酸缩水甘油酯的复合物)和其他二甲基丙烯酸树脂已广泛用于复合材料、封闭剂和粘着剂中。但这些树脂本身对于牙釉质和牙本质并不具有粘着力。当Michaet Buonocore首先应用酸蚀法后,这些树脂才作为牙釉质粘着剂应用于临床。但是,即使应用酸蚀法,也不能有效地将预防材料和修复材料 At present, BIS-GMA resin (a complex of bisphenol A and glycidyl methacrylate) and other dimethacrylic resins have been widely used in composites, sealants and adhesives. However, these resins themselves do not have adhesion to enamel and dentin. When Michaet Buonocore was first applied to acid etching, these resins were used clinically as enamel adhesives. However, preventive and repair materials can not be effectively used even with acid etching
