Micro Motors Develop The Torque Essential To Function Handpieces
Micro Motors Develop the Torque Essential to Function Handpieces
Just about every dental applies requirements to incorporate dental micro motors. They are the devices that develop the torque essential to function handpieces for drilling, buffing, sharpening, and dental burs amongst other motor-driven units. Dental provides such as these permit the dentist to practice their abilities to avoid wasting teeth in the ravages of cavities and the dress in and tear to which teeth fall sufferer to daily. The dental unit is normally equipped with a plurality of dental handpieces, divided substantially into instruments, for example, the turbine and the micro motor, used for removal of dental instruments, and material, for example, the syringe and the polymerizing lamp, used for complementary stages of dental treatment. These developments have also greatly improved the operative parts of dental units, for example, the handpieces, and especially micro motors, which the present invention is concerned with in particular. A handpiece typically comprises a first body, constituting the part by which the handpiece is held and which is equipped on the end of it with a head to which a tool (for example, a burr) can be fitted.
In micro motor handpiece, the first body is connected to a second body, which houses a motor. The connection is coaxial by means of a quick-release fitting on the respective ends of the two bodies. The second body is in turn connected, at its other end, to an endpiece that supplies water or physiological saline, air for nebulizing the liquid, air for cooling the micromotor and electricity for driving the micromotor. The endpiece constitutes the end of a cable that starts at one of the aforementioned handpiece trays on a dental unit and that combines the conduits and wires used to supply the fluids and electricity required for the operation of the handpiece.

The performance of these handpieces, driven by conventional electric motors, has reached the highest possible levels, giving little room for further improvement. The Applicant has therefore designed a handpiece which, instead of a conventional electric motor with brushes, is driven by a ultra micro brushless motor. This optimizes speed control, offers better torque response and silent operation, and reduces friction and heating, thereby increasing the useful life of the motor. In addition to this, the new handpiece can be used for both traditional, conservative treatments and for implants thanks to a constructional architecture that enables it to be fitted with all the tools and accessories currently used on traditional handpieces.
The present invention accordingly provides a dental unit comprising at least one chair, a base positioned next to the chair and mounting a handpiece tray. The tray is equipped with a plurality of operative or auxiliary handpieces for dental operations of traditional conservative type and/or for implants. At least one of the handpieces is fitted with a drive unit consisting of a brushless micromotor presenting a unit for continuously controlling the speed of the brushless micromotor according to parameters that depend on the type of application, that is, traditional conservative type operations or implants.
