Why should dentists use electric handpieces?

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 Benefits 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 “millinginstead of “chopping,” allows for more precise margins in less time, creating happy, thankful patients who spend less time in your chair.

 

Advancements in Electric Handpieces

Just as air-driven handpieces have progressed through the years, electric handpieces are experiencing technological advances at a rapid pace. Here are a few of the recent additions:


Plug-n-Prep
An auto-calibration that allows for air-like “feathering” between 20.000 – 200.000 rpm with the foot pedal. It works off the current air source and no adjustment is required of any other equipment in the office. It works the way you are accustomed to working with air-driven instruments. Therefore, doctors using air-driven handpieces can seamlessly transition to electric handpieces with this feature without a learning curve.

Endo Torque Control
This feature allows the dentist to perform the endo function without the need for additional tabletop device. The dentist can perform endo procedure with ease with torque limit control and an auto reverse process to assist during canal prep. The dentist will experience control and a consistent transference of power from the handpiece to the bur, resulting in more efficient prep. If you are looking to get into Endo, then definitely this feature should be a criteria for moving to electric handpiece systems.

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.
