摘　　要：目的：观察使用白攻自断螺纹钉和石英纤维桩辅助固位状态下，用树脂对前牙冠折再粘接的临床疗效。方法：将冠折后的牙齿进行根管治疗，根据折断的情况选择不同的辅助回位的方法，使用自酸蚀粘结剂和两种不同的树脂进行断冠再接修复。结果：断冠再接的短期内临床效果良好，功能和美观均能达到患者要求，再接3年的总体保存率为83．3％，单纯性牙冠折断的保存率为90．9％。结论：单纯性牙冠折断进行断冠再接方法是短期修复的好方法，冠根联合折断建议选择其他修复方法。Objective;To observe clinical effects on reattachment of crown fractured permanent anterior teeth using composite assisted in self tapping screw or quartz fiber post.
