本文介绍酸蚀技术在修复患儿前牙牙体缺损的应用。酸蚀技术增加了修复体的固位力,这是由于树脂的梳状突和酸蚀处理后的牙釉质表面不规则的超微孔结构之间产生机械性的锁链性结合。这种方法修复外伤和牙釉质发育不全的牙齿有独特的优越性,即技术操作简单,少磨牙,不需要固位装置,可以保存活髓,美观,而且可以一次完成,甚易为患儿所接受。 This article describes the application of acid etching in the repair of anterior teeth defects in children. The acid etching technique increases the retention of the prosthesis due to the mechanical interlocking between the resin comb and the erratic microporous structure of the enamel surface after acid etching. This method to repair trauma and enamel hypoplasia teeth have unique advantages, that is, the technical operation is simple, less molar, no retention device, can save the vital marrow, beautiful, and can be done at once, very easy for children accept.
