| 目的 比较反角高速涡轮牙钻截冠法与传统锤凿劈冠法拔除下颌阻生智齿的临床疗效，探讨应用反角高速涡轮牙钻截冠法拔除下颌阻生智齿的优越性。方法选取临床上需要拔除下颌阻生智齿的120例患者为研究对象，每例患者均需拔除阻生智齿1颗，按就诊顺序分为甲、乙两组，每组60例。甲组采用反角高速涡轮牙钻截冠法拔除，乙组采用传统的锤凿劈冠法拔除。比较两组患者手术时间、术后疼痛、颌面部肿胀、张口受限程度及干槽症的发生情况，并进行统计分析。结果甲组手术时间较乙组明显缩短（P＜0.05），甲组术后疼痛、颌面部肿胀、张口受限程度及干槽症的发生率均明显低于乙组（均P＜0.05）。结论反角高速涡轮牙钻截冠法与锤凿劈冠法在下颌阻生智齿拔除中相比，前者具有手术时间短、术后反应轻、并发症少等优点，值得临床推广应用。 |

| Abstract: |
| Objective To compare the clinical efficacy of anti-angle high speed turbine crown truncation method with that of traditional hammer chisel splitting method for removal of impacted mandibular wisdom teeth. Methods One hundred and twenty cases with impacted mandibular third molar extraction were randomly assigned to receive anti-angle high speed turbine crown truncation method (group A, n=60) or traditional hammer chisel splitting method (group B, n=60) for removal the impacted teeth. The operative time, degree of postoperative swelling, pain and limitation of mouth opening, and the incidence of dry socket were recorded and compared between two groups. Results The mean operative time was significantly shorter in Group A com- pared with that in Group B (P＜0.05). The degree of trauma swelling, pain and limitation of mouth opening, and the incidence of dry socket after operation in group A were significantly lower than those in Group B (P＜0.05 ). Conclusion Compared with the traditional hammer chisel splitting method, the anti-angle high speed turbine crown truncation method has the advantage of shorter operative time, less postoperative responses and fewer complications for pulling the impacted mandibular wisdom teeth. |
