Definitions
- the present invention relates to the field of strawberries, in particular for dental use.
- Strawberries used particularly in dentistry have shapes and dimensions very variable, in addition they are used at different speeds.
- turbine handpieces generally called turbines
- flywheel or modifications of the shapes of the paddle wheels which allow among other things to obtain a greater power so a movement less likely to micro variations.
- An object of the present invention is to design a moderated inertia mill so that the inertia of the rotating assembly is adapted to both the milling cutter and the type of work for which it is intended.
- Another object of the invention is to design a cutter, the insertion of which is facilitated and secure and avoids the gliding of the gloved fingers of the practitioner on the proximal portion of the handle of the cutter.
- a dental drill of the type comprising an active part, a tail with a proximal portion and a distal portion, characterized in that the proximal portion comprises a variable flywheel.
- FIG. 1 schematic view of a conventional dental drill.
- Figure 2 schematic view of a dental bur according to the invention.
- - Figure 3 dental drill according to the invention engaged in a counter-angle head or turbine.
- the dental burs are generally composed of an active part (a) and a handle or tail that can be divided into two parts, on the one hand the proximal part (b) which is intended to remain outside the head of the turbine handpiece or contra-angle, and a distal portion (c) which is intended to enter a handpiece, turbine or contra-angle.
- the said part (c) is generally defined according to the ISO standards in force depending on whether it is strawberry for use on contra angle low or high speed.
- FIG. 2 represents a cutter according to the invention which comprises an active part (1), a distal part (3) for insertion into a handpiece, and a proximal part (2) comprising a variable flywheel ( 4) to adjust a steering wheel according to the dimensions of the active part (1) and / or the work to be done.
- a cutter according to the invention which comprises an active part (1), a distal part (3) for insertion into a handpiece, and a proximal part (2) comprising a variable flywheel ( 4) to adjust a steering wheel according to the dimensions of the active part (1) and / or the work to be done.
- variable flywheel (4) has a smaller diameter (5) located on the side of the active part (1) and a larger diameter (6) on the side of the distal part (3). of the tail.
- the larger diameter base (6) is located at, or very close to, said distal portion (3) so as to serve as a visual cue to the practitioner, which ensures that the cutter is engaged correctly and good depth in the clamping system of the handpiece.
- the envelope (7) of the flywheel is a conical surface of revolution whose function is to smooth the rotational movement by opposing the jolts suffered by the cutter during the dental work.
- the envelope (7) could also be constituted by discontinuous circular bearings of different successive diameters (case not shown).
- a flywheel of about 3 mm and 0.25 g of mass gives satisfactory results.
- the presence of the flywheel allows, by centrifugal effect, to push the watering liquid and any physiological liquids outwards, thus avoiding their penetration into the head of the turbine, handpiece or contra-angle. This effect is accentuated if, judiciously, it gives a shape such that the flywheel has a smaller diameter of the milling side than the handpiece side.
- Another function of the steering wheel is to block the gloved fingers of the practitioner and prevent their sliding on the cutter (see Figure 3).
- Another function also of the steering wheel is to constitute a structural support of the tail of the cutter by opposing the phenomenon of whip that can occur with strawberries used at high speed.
- Another function also of the steering wheel is to constitute a protection of the handpiece against splashes of saliva and other liquids during work.
- the steering wheel can also if it is colored, fulfill a function of visual identification of strawberries placed in a specific support generally used by dentists.
