自1955年Buonocore[1]第一次引进了酸蚀处理技术以来,即成为了正畸托槽和牙釉质粘结成功的重要条件。酸处理虽然提高了树脂对牙齿结构的粘结强度,但是容易导致牙釉质过度丧失。随着研究的进展,新的牙釉质表面处理方法得到了较快发展。而牙釉质酸蚀及龋损后的再矿化,也得到 Buonocore [1] introduced the etching technique for the first time since 1955, which became an important condition for the successful bonding of orthodontic brackets and enamel. Acid treatment, although increasing the bond strength of the resin to the tooth structure, easily leads to excessive loss of enamel. With the progress of the research, the new enamel surface treatment method has been developed rapidly. Enamel acidosis and remineralization after carious lesions, but also get
