摘　　要：目的探讨年轻恒前牙自体断冠再接术的临床疗效。方法选择67例患者92颗外伤冠折的上颌恒前牙，分为断冠再接组（A组，46颗）及复合树脂直接修复组（B组，46颗）。A组使用牙釉质-牙本质粘结剂进行断冠复位再接，B组采用复合树脂直接修复治疗，随诊2年，观察疗效。结果A组成功率为93.47%，B组为89.13%，两者比较差异未见统计学意义（P〉0.05）。结论断冠再接术是治疗年轻恒前牙冠折的一种简便有效的过渡性修复方法。Objective To investigate the clinical effect of autologous rebonding treatment on crown fracture of young permanent anterior teeth. Methods Ninety-two young permanent anterior teeth with crown fracture were selected from 67 patients, then divided into two groups. Group A （46 teeth） was reattached with the original fragment by autologous rebonding treatment, while group B （46 teeth） was rebuilt-up by the composite resin. All patients underwent a 2-year follow-up.Results The success rate was 93.47% in the group A and 89.13% in group B after 2-year follow-up, there was no significant difference between the two groups （P〉0.05）.Conclusions Autologous rebonding treatment is a simple and effective temporary restoration method for young permanent anterior teeth with crown fracture.
