摘　　要：目的观察外科手术冠向复位法对复杂冠根折患牙的临床疗效,为临床诊治提供参考。方法在2017年1月至2019年1月南方医科大学口腔医院综合急诊科就诊的牙外伤患者中,选取复杂冠根折恒牙共计10颗,进行外科手术冠向复位法,随访1年,观察其临床疗效。影像学评估牙周膜愈合方式、牙槽嵴顶骨吸收和根尖周骨密度变化。结果10例复杂冠根折患者的患牙经治疗后全部存留。9例出现牙周膜愈合,1例出现牙根表面吸收愈合,没有出现牙根炎症吸收或进行性吸收。2例患牙伴发牙槽嵴顶骨吸收。所有患牙根尖骨质密度增高,没有出现根尖病变。结论外科手术冠向复位法是治疗前牙复杂性冠根折的可行方法。Objective This study aimed to evaluate the clinical effect of surgical extrusion in the treatment of complicated anterior teeth crown-root fractures. Methods From January 2017 to January 2019, a total of 10 anterior teeth with complicated crown-root fracture were included and surgically extruded in the General Consulting and Oral Emergency Department of Stomatological Hospital, Southern Medical University. Clinical and radiographic parameters including survival rate, periodontal healing, marginal bone loss, and periapical lesion were evaluated. Follow-up period was 1 year. Results All 10 teeth with complicated crown-root fractures survived during follow-up. Radiographic results showed nine cases of healing with normal periodontal ligament and one case of healing with root-surface resorption. The complication of marginal bone loss occurred in two cases. No periapical lesions, inflammatory root resorption, or ankylosis-related replacement resorption was found. Conclusion Surgical extrusion is a safe and feasible method of treating complicated crown-root fractures in anterior permanent teeth.
