Abstract
The active portion of an osseous compression tool for use particularly in dentistry for the preparation of an osseous seat has a cross-section whose perimeter, e.g. of polygonal shape, is defined such that a rotational actuation of the tool around its axis, at least in one direction, preceded or accompanied by its actuation in an axial direction inside the seat, has the effect that the osseous matter is compressed and that the seat is imparted a perimeter of a predetermined shape. In a variant embodiment, a rotation of the tool in the opposite direction allows a scraping or cutting of osseous matter. A tool holder includes a percussion system and allows the translational and rotational actuation of the tool manually or automatically.

43. Osseous compression tool for use particularly in dentistry for the preparation of an osseous seat in view of the placement of an axially inserted implant, the tool comprising an active portion that allows shaping said osseous seat and may be terminated by an apical portion,
characterized in that the cross-sectional shape of the active portion is defined such that a rotational movement of the tool around an axis has the effect that the osseous matter is compressed towards the periphery of the seat and that the latter is simultaneously imparted a determined shape, in that the rotation is preceded or accompanied by a translational movement in the direction of this axis inside said osseous seat while its angular width is essentially determined by the respective type of contour of the cross-section of the tool and by the mechanical qualities of the worked osseous matter, and in that it may be oriented in the clockwise or in the counterclockwise direction or reciprocating in one and in the opposite direction.
