用高速气涡轮牙钻切割法(简称气钻切割法)拔除阻生牙,可以解除患者由于使用骨锤敲击、骨凿劈冠所造成的恐惧,它完全避免了术中剧烈的震动。从1965年起我科开始用气钻切割法拔除各类阻生牙。为了总结气钻切割法拔牙的经验,在1981年5月～10月,我们使用KY—4型高速气涡轮牙钻和头柄45°手机(北京人民手术器械厂生产)拔除阻生牙,系统地观察了100例,取得了满意的效果。现报告如下:
With high-speed gas turbine drill cutting method (referred to as pneumatic drill cutting method) removal of impacted teeth, patients can lift the use of bone hammer percussion, bone chisel split crown caused by fear, it completely avoids the violent intraoperative vibration. Since 1965, our department started to remove all kinds of impacted teeth by drilling with a pneumatic drill. In order to summarize the experience of tooth extraction with pneumatic drilling, we removed the impacted tooth using a KY-4 high-speed gas turbine tooth drill and a 45 ° handpiece (manufactured by Beijing People's Surgical Instrument Factory) between May and October 1981 Observed in 100 cases, and achieved satisfactory results. The report is as follows:
