Instructions for Use

Pre-Operative Procedure

1. Inspect the Universal Hex Driver Key for cleanliness, wear, deformation, or damage.
2. Verify compatibility with the implant system and prosthetic component.
3. Clean and sterilize the instrument before use.
4. Ensure that the prosthetic component and fixation screw are free of debris.

Prosthetic Component Installation

1. Engage the 1.77 mm hex tip securely into the prosthetic screw.
2. Insert the screw into the abutment or restoration according to the manufacturer's protocol.
3. Tighten the screw manually until initial seating is achieved.
4. If required, connect the driver to a compatible torque wrench or ratchet.
5. Tighten the screw to the recommended torque value specified by the implant manufacturer.
6. Verify complete seating and stability of the restoration.

Prosthetic Component Removal

1. Engage the 1.77 mm hex tip fully into the screw head.
2. Apply controlled counterclockwise rotation.
3. Remove the screw and component carefully.
4. Inspect the screw and restoration for wear or damage before reinstallation.
