Light-activated resin-modified glass-ionomer cements have been shown to be satisfactory adhesives for the direct bonding of metal brackets in selected cases. They have the advantage over composite resins in that no etching of the enamel is required, thereby preserving the integrity of the enamel prisms. Debonding of brackets carries less risk of mechanical damage to tooth structure and the long-term fluoride leach reduces the incidence of demineralisation around bracket margins. This paper describes the clinical technique for bonding metal brackets with these materials and some recommendations when debonding.
光固化树脂改性玻璃离子水门汀已被证明在某些情况下是用于直接粘结金属托槽的理想粘结剂。与复合树脂相比，它们的优势在于无需酸蚀牙釉质，从而保持牙釉质棱柱的完整性。托槽脱粘时对牙齿结构造成机械损伤的风险较小，而且长期的氟释放可降低托槽边缘周围脱矿的发生率。本文描述了使用这些材料粘结金属托槽的临床技术以及脱粘时的一些建议。
