摘　　要：目的评价后牙定向骨凿在拔牙术的分牙(劈冠和分根)操作中的临床可行性及其优势性。方法对301颗均存在邻牙阻力和/或牙根骨阻力的各类患牙,随机采用后牙定向骨凿(试验组)或普通骨凿(对照组)的拔牙器械行分牙操作,以术前预测与术中操作结果的完全一致视为成功标准,从智齿邻牙阻力劈冠、错位牙邻牙阻力劈冠、后牙牙根骨阻力分根三方面获取研究数据,进行统计学分析。结果试验组(后牙定向骨凿)和对照组(普通骨凿)在智齿邻牙阻力劈冠和后牙牙根骨阻力分根中的差异,以及二组总差异中均有统计学意义(P<0.05)。结论后牙定向骨凿在分牙(劈冠和分根)操作中的精确度优于普通骨凿,值得临床推广。Objective To evaluate the clinical feasibility and advantages of directional osteotome of posterior teeth in the operation of exodontia.Methods Total of 301 different kinds of ill teeth with exsit resistance between the adjacent teeth or teeth roost were randomly operated by the extraction instruments of directional osteotome of posterior teeth（an experiment group） or common osteotom（a control group）.The complete consistency between the preoperative prediction and intraoperative results was considered as a successful standard.The data to be analyzed statistically were got from three aspects of traditional chisel from the resistance of opsigenes adjacent teeth,the resistance of malposed adjacent teeth and the resistance of teeth roots of posterior teeth.Results There was statistical significance between the experiment group and control group（P0.05）.Conclusion The accuracy of directional osteotome of posterior teeth in the operation of exodontia is superior to the common osteotome and it is worthy for clinical popularization.
