GMI torque wrenches are divided into five basic groups: manual wrenches, ratchet wrenches, wrenches with HP connection, lab wrenches and adapters. Manual wrenches are used for the final tightening of the cover screws and the healing abutments, as well as the initial tightening of the clinic screws. Ratchet and HP connection wrenches are used for the implant insertion and for the final tightening of the abutments or screws. Lab wrenches are designed to facilitate the work of the prosthetic lab and finally, adapters provide a link between manual and ratchet wrenches and the tips with hand-piece connection.
