目的:探讨运用阻生牙专用超长裂钻对于拔除下颌角缩窄型患者下颌阻生智齿的影响。方法:收集2010年1月~2017年1月需拔除下颌阻生智齿的下颌角缩窄型患者11例,并运用高速涡轮手机联合超长裂钻拔牙法拔除阻生智齿,观察分析术中、术后下唇麻木、张口受限发生等并发症。结果:全部患者术中、术后均无颞下颌关节损伤、张口受限,下颌骨骨折,咬合关系紊乱、皮下气肿,唇、舌神经麻木等并发症出现。结论:应用阻生牙专用超长裂钻拔除下颌角缩窄型下颌阻生智齿的效果较为理想,值得临床推广。
Objective: To investigate the effect of using special super long cracked teeth for mandibular impacted mandibular wisdom teeth removal. Methods: Eleven patients with mandibular angle narrowing mandibular impacted wisdom tooth were collected from January 2010 to January 2017. High-speed turbine handpieces combined with extra-long split-tooth extraction were used to remove impacted wisdom teeth. Observation and analysis During operation, Postoperative lower lip numbness, mouth restriction occurred and other complications. Results: All patients had no complications of temporomandibular joint injury, limited mouth opening, mandibular fracture, occlusal relationship, subcutaneous emphysema, lip and tongue numbness in operation and postoperatively. CONCLUSION: The effect of mandibular angle narrowing mandibular impacted wisdom tooth extracted by special super long cracked teeth of impacted teeth is ideal and worthy of clinical promotion.
