直接粘合正畸托槽在矫正完成后需除去,并使经酸处理的釉质表面恢复正常,关于酸处理与粘合强度间的关系已有许多研究,而最近才有对除去托槽后,残留于牙面粘合剂问题的研究。作者对使用两种不同的粘合剂粘合正畸托槽及使用不同的方法除去牙面残留粘合剂进行了扫描电子显微镜(SEM)研究。 Direct bonding orthodontic brackets to be removed after the correction is completed, and the acid-treated enamel surface returned to normal, the relationship between acid treatment and adhesive strength have been many studies, and recently there is no brackets removed, Study on the Problem of Residual Adhesive in Teeth. The authors performed scanning electron microscopy (SEM) studies on orthodontic brackets using two different adhesives and using a different method to remove residual dental adhesive.
