Abstract

A screw connection device, particularly for osteo-integrated plants, comprises a first element (I) and a second element (M) which are clamped to each other by means of a connection screw (9). Between the two elements (I, M) means (11) are interposed which are adapted to be deformed elastically and/or permanently as a result of the tightening of the connection screw (9), so as to enable the operator to carry out the tightening operation in a precise and controlled manner, untill reaching a predetermined force, which can be predetermined experimentally or by calculation, this reaching being signalled optically and/or acoustically by signalling means connected to the electronic processing means.
