摘　　要：目的探讨分根术应用于微创拔除前牙区残根的临床效果。方法选取2015年1月至2016年12月来我院口腔颌面外科门诊就诊需拔除前牙区残根的患者400例,依就诊次序奇数纳为实验组,偶数纳为对照组,各200例。实验组利用涡轮钻针先行将残根近远中向分根后,结合微创拔牙刀将残根拔除;对照组术中不分根,仅利用微创拔牙刀拔除残根。对比两组患者手术时间、术后拔牙窝唇侧骨板完整率、疼痛程度及患者满意度。结果实验组手术时间平均为(2.31±0.88)min,与对照组比较差异有统计学意义(P<0.05)。实验组在唇侧骨板完整率、无痛率及满意率方面均优于对照组,差异均有统计学意义(P<0.05)。结论采用分根术微创拔除前牙区残根,拔牙窝唇侧骨板几乎没有破坏,创伤更小,利于后期的种植修复,值得临床推广应用。Objective To investigate the clinical effect of minimally invasive extraction of anterior tooth residual root after root separation. Methods A total of 400 patients receivinganterior tooth residual root extraction were collected in the clinic of oral and maxillofacial surgery department between January 2015 and December 2016. The patients were divided into a control group and a study group according to their sequence to see the doctor, with an odd for the study group and an even for the control group. In the study group, residual roots were separated me- siodistally by high speed turbine before using minimally invasive extraction tool ; while in the control group residual roots were extracted only using minimally invasive extraction tool. The surgical duration, postoperative damage rate of the lip side plate, degree of pain and patient satisfaction in the two groups were analyzed. Results The surgical duration was shorter in the study group compared with the control group （P 〈 0.05）. The postoperative damage rate of the lip side plate and the degree of pain were lower, while patient satisfaction was higher in tbe study group than in the control group （P 〈 0.05）. Conclusions The postoperative damage rate of the lip side plate is significantly lower in minimally invasive extraction of anterior tooth residual root after root separation. Smaller trauma is condu- cive to the implant afterwards. Root separation in minimally invasive extraction of anterior tooth residual root is valu- able for clinical application.
