Are Electric Handpieces Necessary for Dentists? Why?

As is known to dentists,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.

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 handpiece to blend in with the dental unit.


Top Benifits of Electric Handpieces

Using the latest versions of electric handpieces can allow you to be more precise with less noise and vibration, which benefits both you and your patients. With more comfort and less menacing sound, patients will experience a calmer, more relaxed visit to your office. Plus, less noise protects your hearing too.

But perhaps some of the biggest benefits to electrics are the speed and torque they offer. While the torque of air-driven handpieces advanced over time, 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.

Also, bur chatter is no longer an issue with electric high speed handpieces. At turbines, the older the bearings and the O-Rings for centricity, the more a bur can wobble, causing chatter. But because electric handpieces rely on solid gear-to-gear contact and rigid bearing support, the bur does not wobble, therefore eliminating chatter. Without chatter, you can perform more finite cutting and operate with more precision and less effort. This also means the bur is in contact with your patients’ teeth for less time, resulting in reduced sensitivity. This process, called “milling” instead of “chopping,” allows for more precise margins in less time, creating happy, thankful patients who spend less time in your chair.

New Designs

Significant advances are also being made with light-emitting diodes (LEDs), smaller head sizes and ergonomic designs that will help maximize a doctor's field of vision in the mouth. These advancements offer less stress on the operator, plus more maneuverability and control, which equals more comfort for the patient.

Switching from air to electrics is now made easy for you. Update your pneumatic treatment unit with KaVo’s brand-new ELECTROmatic system and benefit from all the following electrics advantages:

  • Constant torque : Only an electric motor maintains the cutting speed under nearly any load — for smoother and more precise preparations.
  • Controlled speed : Electronically controlled, defined programmed speed within a large speed range enables many kinds of preparations.
  • Very quiet : Working at a very low sound level, without the whine of air driven motors — for relaxed and focused treatments.
  • Versatility : Electric allows to perform high-speed, low-speed and endodontic applications with light — perfect for almost any procedures.
