Rescue kit for removing fractured abutment screws and abutments. Guided counter-clockwise drilling, re-tap for the internal thread. Purchase or rental.
| Problem | Solution in the ESR Kit |
|---|---|
| Fractured abutment screw | Guide + SR drill (counter-clockwise), then SR tip to unscrew |
| Screw fragment still protruding | Screw holder grips the fragment directly |
| Fractured abutment | AR tip in the screw channel, loosen counter-clockwise |
| Stripped screw hex | Ø 0.8 mm round bur for a hole or slot, then mini AR tip or slot driver |
| Damaged implant internal thread | Re-tap clockwise at approx. 30 Ncm |
1. Remove the abutment from the implant.
2. Insert the matching guide and align its hex with the internal hex of the implant.
3. Place the ESR handle on the guide, insert the SR drill into the contra-angle and seat it on the screw fragment.
4. Drill counter-clockwise at 1,200–1,500 rpm with light pressure and irrigation until the red marking on the drill disappears inside the guide.
5. Remove the guide and thoroughly suction off metal debris.
6. Insert the SR tip into the guide and engage it in the hole with moderate pressure.
7. Turn counter-clockwise until the screw fragment disengages from the thread.
▶ In the video: OSSTEM demonstrates the procedure on a fractured screw and abutment case.
