【摘要】 目的:观察弹性结扎法治疗纵折后牙的临床效果。方法:86颗纵折后牙,在根管治疗前采用弹性结扎法结扎固定患牙,待根管治疗完成后,去除结扎丝,行全冠修复。结果:治疗后1、2、3 a的成功率分别为97.67%、93.02%和88.37%。结论:劈裂牙在根管治疗前进行弹性结扎,可有效防止治疗中和治疗后牙体折裂,有效保存患牙。更多还原

【Abstract】 PURPOSE: To evaluate the clinical effect of vertically fractured posterior teeth treated with elastic ligation.METHODS: Eighty-six vertically fractured posterior teeth were chosen to be treated with elastic ligation for external fixation before root canal therapy(RCT), and then full crown prostheses were made for rehabilitation. RESULTS: The success rate after 1 year, 2 years and 3 years were 97.67%, 93.02% and 88.37%, respectively. CONCLUSIONS: Elastic ligation for vertically fractured posterior tooth before RCT can effectively prevent tooth fracture during treatment and preserve the tooth for functional use.更多还原
