Objective To investigate the therapeutic results on replantation of vertical fractured posterior teeth after bonding with glass ionomer cement and fixation with metal post. Methods A total of 40 vertical fractured posterior teeth were treated by extraction,root canal therapy,bonding with glass ionomer cement.fixation with metal post, replantation and coronal restoration. 36 of the 40 posterior teeth were completely followed up for 2 years and evaluated. Results Among 36 vertical fractured posterior teeth observed,the the successful reserved rate of 6 months was 100.00% (36/36),one year was 88.89% (32/36),two years was 80.56% (29/36) There were statistical significant differences of the reserved rate in difference period after therapy, the reserved rate became lower with observation time became longer. Conclusion The therapeutic results were satisfied with a 2-year reserved rate, and the method can be worth of clinical application.%目的:对桩钉辅助玻璃离子粘结固定冠根纵折的后牙行再植术并行冠修复的临床效果进行观察、评价.方法:选择40例牙体相对完好、牙周情况良好的纵裂的后牙,拔牙后即刻体外完成根管治疗,用玻璃离子粘固剂粘结并复位,冠部横向钻通,插入并粘结根管桩钉辅助固定,再植入牙槽窝,2个月后行全冠或连冠修复,随访2年,观察疗效.结果:除失访4例外,6个月的成功保存率为100.00％(36/36),1年的保存率为88.89％(32/36),2年的保存率为80.56％(29/36),成功率随术后时间延长而下降.结论:正确选择适应证,对桩钉辅助玻璃离子粘结固定冠根纵折的后牙再植治疗,可获得一定的效果满意,为临床保存治疗提供多一种选择.
