Compressed air handpiece including a handle connected to a head housing a turbine. The turbine includes a moving wheel from a periphery of which extends a plurality of blades which define an outer diameter of the moving wheel. The handpiece also includes injection means, whose function is to direct onto the blades of the moving wheel a compressed air flow whose pneumatic energy is converted into kinetic energy when the compressed air flow strikes the blades of the moving wheel. The injection means take the form of an independent insert inside which is arranged a compressed air flow feed pipe and which is mounted inside the handle of the handpiece.

A dental tool is disclosed that includes an operational unit, a neck region and a handle region, in which the neck region is S-shaped. The operational unit can further include a tongue retractor, a flap retractor or a combination thereof. A suction mechanism may be added for eliminating fluids. The neck region may further contain a lateral bend, a rotation of the working end or both. The proximal end of the handle region, opposite the operational unit, may further include any useful apparatus, such as a periosteal elevator or periosteal retractor.

The invention relates to a handpiece head (1) comprising a housing (2) and a closing cap (3), wherein the housing (2) is releasably connected to the closing cap (3) by means of a screw connection (4). The closing cap (3) comprises at least one recess (8) or at least one elevation (7), wherein the housing (2) correspondingly comprises at least one elevation (7) or at least one recess (8). When the closing cap (3) is screwed in, the elevation (7) on the housing (2) engages in the corresponding recess (8) on the closing cap (3) or the elevation (7) on the closing cap (3) engages in the corresponding recess (8) on the housing (2), so that an inadvertent release of the closing cap from the housing (2) as a result of vibrations of the handpiece head (1) is prevented by the engagement.
