两种外科动力钻在微创拔牙中的联合应用

目的　研究两种外科动力钻在微创拔牙中的联合应用。方法：60例埋伏牙通过CBCT准确定位，利用气动式外科专用切割手机联合Komet外科磨骨球钻精确去骨；联合Komet外科分牙车针彻底分牙，微创拔除患牙。结果：60例患牙均成功拔除，手术时间8~35 min，平均18 min。所有患者术后均无明显肿痛，无1例患者发生术后感染、舌麻木、邻牙损伤等并发症，伤口均一期愈合。结论：使用气动式外科专用切割手机联合Komet磨骨球钻去骨，加长型裂钻分牙，拔除口腔各类埋伏阻生牙，微创高效，适合推广。

Combined application of two kinds of surgical burs in minimally invasive tooth extraction

Objective To study the combined application of the extraction of impacted teeth with two kinds of surgical burs. Methods After CBCT examination, 60 impacted teeth were extracted by minimally invasive technique with surgical impact air handpiece and Komet burs. The surgical round bur would be used for accurate osteotomy, and the surgical fissure bur for sectioning the tooth. Results 60 patients were extracted successfully in 8-35 min (18 min on average). No complications occurred, such as severe swelling, wound infection, numbness of tongue or root injury. All wounds healed in one stage. Conclusion The deeply impacted teeth extraction with 2 kinds of surgical burs is safe and feasible, which improves the surgical efficiency and reduces the morbidity rates effectively, and is suitable for promotion.
