  • ※ One-time use of the F/R Screw is recommended (bending or fracture may happen if more than 100 N.cm and using twice may be possible if less than 100 N.cm).
  • ※ Sufficient Irrigation required when removing fixture.
  • ※ When the maximum torque is exceeded, the fixture may be bent or fractured.
  • ※ If fixture can not be removed even with maximum torque,
    remove Fixture Remover & F/R Screw, remove bones around fixture while using Round Bur and retry to remove.
2. Screw Removal System
Talon Drill

  3. ③ Insert the Talon Drill into the I Guide Hole.
  4. ④ Remove the screw by pressing force (counterclockwise, 60 ~ 80 rpm).

※ If the I Guide and fixture could not be correctly connected, the path is not correct.

Reverse Drill & Screw Remover

If the screw could not be removed by the Talon Drill
