The invention relates to an arrangement to be used together with a tool for mechanical tightening of a screw connection in a bone-anchored dental implant without the tissue which surrounds the implant being stressed. The arrangement comprises a first, tubular part (6), which is intended to be rotationally locked to the implant, and a second part in the form of an arm (8) which is rigidly connected to the first part and extends out essentially at right angles from the latter. The arm (8) is provided with a U-shaped fork (7) which interacts with the stationary part (1) of the tightening tool so that undesirable rotation movements are prevented during the tightening of the screw connection. The U-shaped fork (7) is mounted pivotably on the arm in order to allow stress-relief and release of the tightening tool after tightening has been completed.
L'invention concerne un dispositif à utiliser conjointement avec un outil pour serrer mécaniquement un raccord à vis dans un implant dentaire ancré dans l'os, sans que le tissu entourant l'implant ne subisse de contrainte. Le dispositif comporte un premier élément tubulaire (6) destiné à être bloqué en rotation sur l'implant, et un second élément en forme de bras (8) relié rigide au premier élément et s'étendant essentiellement à angle droit par rapport à ce dernier. Le bras est doté d'une fourche en U (7) qui interagit avec l'élément stationnaire (1) de l'outil de serrage de sorte que tout mouvement de rotation indésirable soit empêché pendant le serrage du raccord à vis. La fourche en U (7) est montée pivotante sur le bras, ce qui permet la relaxation des contraintes et le dégagement de l'outil de serrage une fois le serrage terminé.
