摘　　要：目的:观察分析年轻恒切牙复杂冠根折经根尖屏障术结合外科牵引再植治疗后保存断冠的临床效果。方法:选取外伤致复杂冠根折的年轻恒切牙12颗,局麻下采用根尖屏障术封闭根尖区,经牙槽内移植的外科牵引牙根至所需位置,纤维桩和桩核树脂对断冠行内固位和树脂美容冠修复。结果:12例复杂冠根折外伤牙平均随访时间为1年;经治疗后1例出现牙根表面吸收,2例发生边缘骨丧失,2例发生断冠脱落,但所有病例并未见根尖周病变,牙松动、移位和根外吸收发生。结论:根尖屏障术结合外科牵引再植术可以作为处理年轻恒切牙复杂冠根折的一种相对简单有效的方法。Objective:To evaluate the clinical effect of conserving the broken crown of young permanent incisors with complex crown-root fracture after apical barrier surgery combined with surgical extrusion.Methods:Twelve young permanent incisors with complex crown-root fracture following dental trauma were included in the study.The apical area was closed by apical barrier under local anesthesia,and then the teeth were surgically extracted to a required position.Crowns were restored with fiber-reinforced posts and composite resin veneers.Results:The average follow-up period was 1 year,the most common complications including one tooth with surface resorption,2 teeth with marginal bone loss and 2 teeth with crown shedding,but no periapical lesions,tooth mobility or root resorption occurred in all cases.Conclusion:Apical barrier combined with surgical extrusion can be used as a feasible and effective method for complex crown-root fracture of young permanent incisors.
