摘要：

目的比较恒前牙牙本质固位钉结合双层固化树脂断冠再接与常规断冠再接的临床疗效。方法将外伤冠折片保留完整的38例患者的49颗龈上冠折上颌恒前牙随机分为实验组（21颗）和对照组（28颗），分别采用牙本质固位钉结合双层固化树脂行断冠再接和常规断冠再接（双层固化树脂行断冠再接）。治疗后第1、6、12个月复查，进行疗效评价。结果术后1年实验组断冠再接成功率为95%，对照组断冠再接成功率为64%，二者之间的差异有统计学意义（P<0.05）。结论牙本质固位钉结合双层固化树脂断冠再接的临床疗效好于自体断冠再接。

Abstract:

Objective To compare the clinical effect between reattachment of permanent anterior teeth with crown fracture using dual-cured resin combined with dentin pin and conventional method. Methods 49 permanent anterior teeth of 38 patients which had intact incisal edge segments were divided into two groups. In experimental group reattachment was conducted by dual-cured resin combined with dentin pin, while in control group only dual-cured resin was adopted. Cases were assessed clinically by one year’s followed up. Results The success rate was 95% in experimental group and 64% in control group after one-year’s follow-up（P<0.05）. Conclusion The clinical effect of reattachment with dual-cured resin combined dentin pin to treat anterior crown fracture is superior to conventional method.
