Osseous preparation tool used in dental medicine and device for the use thereof

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, 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, and in that said cross-sectional shape is other than circular, the non-circular character being defined as the fact that the relative distance between the diameter of the circle passing through the point or the set of points of the cross-section furthest from the rotation axis and the diameter of the circle passing through the point or the set of points of the cross-section nearest to said axis is equal to or greater than 0.5%.
