How to operate the electric dental handpiece?

Electric handpiece systems (electric handpieces) consist of a control unit, cord, micromotor and various attachment or handpiece options. Many systems easily connect to existing dental units. Systems require between 110 and 230 VAC, connect to the dental unit turbine tube with compressed air (40-60 psi) and use the existing dental unit foot control. It works by depressing the foot control, which activates the micromotor to produce the electric energy required to rotate the bur.

The electric handpieces offer constant torque with fully adjustable bur speed – which can be adjusted with programmable switch or the foot control. This means that the bur will not slow down or stop, regardless of speed or material being cut.

There are several ways the operator can control the speed of the bur, including: the foot pedal, interchangeable attachments, programmable functions, up and down buttons and arrows, and potentiometers or control knobs. Externally mounted units can be quickly connected and disconnected in a short amount of time and can easily fit on a bracket tray. Internally mounted options, on the other hand, allow the control pad and dental handpiece （coxo dental handpiece） to blend in with the dental unit.
