自酸蚀剂材料在口腔修复正畸托槽粘接中的应用

目的：总结近年有关自酸蚀剂粘接正畸托槽的现状。方法：由作者应用计算机检索万方数据库中与使用自酸蚀剂粘接正畸托槽有关的文献,检索时限为2000-09/2010-08。检索关键词：自酸蚀剂;托槽;抗剪切强度。纳入标准：①选入针对性强,相关度高的文献。②排除一些重复性研究。对资料进行初审,并查看每篇文献后的引文。结果：共20篇文献符合标准,自酸蚀剂粘接剂与传统釉质粘接剂比较,正畸托槽的抗剪切强度相近。两种方法在托槽脱落后的釉质粘接材料残留无显著差异。结论：自酸蚀剂与传统釉质酸蚀粘接剂比较,其抗剪切强度可靠,粘接剂残留指数低,能满足粘接正畸托槽的需要。

Application of self-etching agent in orthodontic bracket bonding of oral prosthodontics

OBJECTIVE： To summarize the research progress of orthodontic bracket bonding with self-etching agent in recent years. METHODS： A computer-based retrieval of Wanfang database was conducted for articles about orthodontic bracket bonding with self-etching agent, retrieval time is from September 2000 to August 2010. Key words are ＂self-etching agent; bracket; shear strength＂. Inclusion criteria： （1） directly targeted and highly relevant literatures. （2） Repetitive researches were excluded. All data were preliminarily screened, and citations after each article were checked. RESULTS： Totally 20 literatures met the inclusive criteria, compared with traditional adhesive enamel, self-etching adhesive agent has a similar shear strength of orthodontic bracket. There was no significant difference between two methods in the enamel adhesive residual after the bracket removed. CONCLUSION： Compared with the traditional enamel etching adhesive, the self-etching agent has a reliable shear strength and low remnant index of the adhesive agent, thus it can meet the need for orthodontic bracket bonding.
