The Screw Remover Kit is a surgical tool designed to remove screws that have fractured inside an implanted fixture. After the screw is removed, a new abutment may be connected to the fixture.
Components
1. Claw
This is a surgical tool designed to remove a screw that has fractured inside the fixture.
After selecting the size appropriate for the screw to be removed, it is used by connecting a guide to the fixture (Conical/Internal/External Guide). It is then connected to the Shank Driver, and the fractured screw can be removed by rotating by hand in the reverse direction. If the fractured screw cannot be removed using the Claw, it can be removed using the Reverse Drill and the Screw Remover.

2. Reverse Drill
- This is a tool designed to create a hole on the fractured face of the screw for use with the Screw Remover.
- After selecting the appropriate Reverse Drill for the size of the screw to be removed, it is used by connecting a guide for the fixture (Perfect/Conical/Internal/External Guide). The depth of the drill can be adjusted from 1 mm to 3 mm, as the drill body has markings.
- Removal of an M1.6 size screw typically utilizes the Claw.
- Although different manufacturers produce different sizes of abutment screws, they typically utilize screws of size M1.6, M1.8, M2.0, or M2.5, except in rare cases. ("M" stands for a metric screw. The number indicates the external size of the screw. For example, "M1.6 Screw" indicates a metric screw with an external diameter of 1.6 mm.)

3. Screw Remover
- This is a device designed to remove a fractured screw. Insert a Screw Remover appropriate for the size of the hole formed using the Reverse Drill, and rotate at a low speed (at or below 80 rpm) in the reverse direction.
- The Screw Remover is designed in a tapered shape to increase friction as it turns, which can help loosen the screw.

5. Perfect Guide & PG Hand Driver
- The Perfect Guide acts as a guide for the Reverse Drill. It is used when the screw is fractured at the lower part of the female screw inside the fixture. It is connected to the PG Hand Driver and is directly applied to the fixture female screw.
- The Perfect Guide has a stop structure inside that limits the Reverse Drill from drilling more than 2 mm.
6. Conical, Internal, External Guide
- These act as the guide when using the Reverse Drill. They are used when the Perfect Guide cannot be used, or if the screw was fractured at a location deeper than 2 mm into the lower part of the female screw inside the fixture.
- The guide appropriate for connecting to the fixture should be selected.
7. SR Driver Holder
This can be affixed to the fixture by connecting it to the 3.5 Double Hex part of the Conical, Internal, or External Guide.
