Abstract: A head assembly for attaching to a dental instrument has a body, a rotary shaft with a pinion thereon, at least one retractable catch latching lever and a retractable catch. The rotary shaft has a central bore suitable for receiving a shank of the dental instrument therein. The latching lever has a peg engageable with an annular latching groove of the shank of the dental instrument. The catch has a positioning plane coinciding with the drive flat of the instrument. The body has a circular opening closed off by a push button cooperative with the rotary shaft so as to release the shank of the dental instrument.

Abstract: The invention relates to a device for holding a dental instrument in the head of a contra-angle, an instrument of the type comprising, in its upper part which is inserted into the head of the contra-angle, a lateral flat for rotating it and an annular groove for axially retaining it, characterized in that the shank receiving the handle of the instrument, comprises a transverse cutback (7d), offset with respect to the longitudinal axis (7e) of the shank, made in the end of the shank and emerging in the bore (7b), the width (1) of the cutback being such that it allows the handle of the instrument to be engaged so that, on the one hand, the lateral flat of the handle is in contact with the wall (7f) of the cutback, closest to the longitudinal axis (7c), so as to ensure rotational coupling, and that, on the other hand, the shoulder of the flat of the handle abuts against the bottom (7c) of the longitudinal bore (7b) of the shank, in order to act as an axial stop in the direction of insertion.Preferably, the device is in the form of a cartridge comprising, already assembled, a shank (7), a shank bearing (10), a resilient ring (8), a push-button (13) with a spring (12), and optionally a ball bearing (11).

Abstract: Atomizing process and device for dentistry handpieces or angle pieces, characterized in that it involves generating, in the region of the receptacle of the tool in the handpiece or angle piece, a suction effect putting the vicinity of the cutter receptacle under a slight vacuum under the effect of an air cone of which the apex is situated at the point where the tool is working, the other function of this air cone being to direct the cooling fluid by means of an effect of the COANDA type, thereby reducing the consequences of turbulences attributable to the rotation of the tool or instrument.
