Abstract
A holding device allows for tightening of a screw joint in a bone-anchored dental implant without imposing stress upon the tissue surrounding the implant. The device includes a first part which is rotationally locked in relation to the implant and a second part in the form of an arm which is rigidly connected to the first part, extends substantially perpendicularly thereto and is provided with a holding portion which interacts with the stationary part of the tightening tool to prevent undesirable rotary movements.
