摘要:

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。

Abstract:

The present paper introduced the use of acid etching technique to restore the defective anterior teeth in child patients.Acid etched resin restorations demonstrated increased retention due to mechanical interlocking of resin tags in the irregular microporosities of the etched enamel surface.It offered an unique advantage in the restoratic of fractured and hypoplastic teeth.The technique was simple minimum tooth removal was required,no post retention was necessary,the vitality of the pulp could be preserved,the procedure could be finished in one appointment and it improved the esthetic appearance.It provided a high level of clinical acceptance.
