Intsructions:
- Use the G-drill to remove the dentin until the tip of the G-drill is close to or touches the surface of the broken file.
- Select the appropriate size of guide cobalt (80,90,110 size) and continue to remove the dentin channel.
- After cutting the dentin, according to the size of the broken file, choose a suitable size of drill, grind the file channel at low speed in reverse rotation (recommended speed 150 rpm)
- Using the cricothyroid sleeve to remove the dentin around the broken file by counter-rotating at low speed. Until the broken file is exposed 2-3m, if the root canal is too curved for the cricothyroid sleeve to penetrate deeply, use the guide drill (60-70 size) to remove the dentin around the broken file at low speed until the broken file is exposed 2-3mm.
- Install a suotable size of clamping sleeve.
