目的:探讨常规方法(骨凿劈冠法)联合涡轮钻法拔除下颌阻生第三磨牙的临床效果。方法:对196例下颌阻生智齿采用常联合法拔除。结果:联合法比单一常规法手术时间短,患者痛苦小,术中、术后并发症少。结论:常规方法联合涡轮钻法拔除下颌阻生第三磨牙,易为医生掌握,手术更安全。 Objective: To investigate the clinical effect of conventional method (osteotome split crown method) combined with turbodrill extraction of mandibular impacted third molars. Methods: 196 cases of mandibular impacted wisdom teeth were removed by the common method. Results: The combined method was shorter than the single conventional method, the patients had less pain, less intraoperative and postoperative complications. Conclusion: Conventional method combined with turbodrill extraction of mandibular impacted third molars is easy for doctors to master and the operation is safer.
