Objective To compare the efficiency of two methods of tooth extraction and the incidence of intraoperative and postopera?tive complications,as well as to provide basis for the new clinical therapies. Methods 132 cases were divided into two groups ran?domly,using surgaical impact air handpiece and traditional method respectively. The extraction time, intraoperative and postoperative complications of two groups were compared. Results The extraction time of experimental group was shorter than the control group and there was significant difference between the two groups(P<0.05). The incidences of root fracture, gingival laceration, and injury of temporomandibular joint of experimental group were lower than those in the control group,and the difference was statistically significant (P<0.05). There was no significant difference in the lingual bone plate fracture,tooth mobility,nurve injuries and tooth slip into fas?cial space in the two groups(P>0.05).The incidences of postoperative pain, limited mouth opening, postoperative swelling and dry socket in the experimental group were lower than those in the control group,and the difference was statistically significant(P<0.05). Conclusion The new method with surgical impact air handpiece can improve efficiency,as well as reduce the incidence of complica?tions,and it's worth the clinical expansion.%目的 通过比较两种拔牙方法的效率及术中、术后并发症的发生率,为临床开展新疗法提供依据.方法 将132例患牙随机分为两组,分别使用气动式外科专用切割手机拔牙法和传统拔牙方法,比较两组的拔牙时间及术中、术后并发症的发生情况.结果 涡轮机组拔牙时间少于对照组(P<0.05).涡轮机组牙根折断、软组织损伤及颞下颌关节损伤等术中并发症发生率低于对照组(P<0.05),涡轮机组舌侧骨板骨折、邻牙损伤、神经损伤及牙体滑入间隙等术中并发症发生率与对照组比较差异无统计学意义(P>0.05),涡轮机组术后疼痛、张口受限、面部肿胀及干槽症发生率明显低于对照组,差异有统计学意义(P<0.05).结论 气动式外科专用切割手机及配套工具的使用提高拔除下颌低位阻生齿的效率,降低并发症发生率,值得临床推广.
