Harnessing the Power of Electric Handpieces

Introducing KaVo’s new MASTERmatic™ series

Because the handpiece is the workhorse of the general practitioner’s armamentarium, the selection of the right equipment is critical. Only relatively recently have dentists in North America begun to fully appreciate the benefits of the electric handpiece, which include high power, consistent torque, concentric bur movement, and low levels of vibration and noise.

Advantages of Electric Handpieces

Using the latest versions of electric handpieces can allow clinicians to be more precise with less noise and vibration. A less menacing sound means patients will experience a calmer, more relaxed visit to your office—with the additional benefit of protecting the dental team’s hearing from excess noise.

While air-driven handpieces lose cutting power when they meet resistance, electric handpieces offer constant torque with fully adjustable bur speed—which can be adjusted with programmable switch or the foot control. Its constant torque means the bur will not slow down or stop, regardless of speed or the material being cut.

In addition, bur chatter is no longer an issue with an electric handpiece. With traditional handpieces, the older the bearings, 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, eliminating chatter. Without chatter, dentists can perform more finite cutting and operate with more precision and less effort. It also allows for more precise margins in less time, meaning reduced chairtime.

Concerns About Electric Handpieces

One of the most common misconceptions about electric handpieces is that they are heavy. This may have been true at one time, but current micromotors and attachments are very close in weight to the air-driven handpieces. The weight and length of the motor and attachments have been reduced by 40% and 15%, respectively.

Some dentists have suggested balancing the electric motor in the area between your thumb and index finger. It is simply a matter of balance, concentration, and allowing yourself to adjust.

An Electric Handpiece Innovation

The recently launched MASTERmatic series from KaVo combines the power and features of today’s most advanced electric handpieces with a sleek, ergonomic design. MASTERmatic LUX M25 L High Speed is a standard head electric handpiece with a 20% reduction in head size compared with KaVo 25 LPR handpiece. MASTERmatic LUX M05 L Mini High Speed is KaVo’s first mini-head electric handpiece, and boasts a 43% reduction in head size. The compact design and patented angulation of both models allows for easy access, even in the posterior.

With the KaVo Triple Gear System, a speed range up to 200,000 rpm, and ceramic bearings, the MASTERmatic series offers high power delivered through a smooth, quiet, and low-vibration handpiece. Both handpieces in the series feature a hygienic Plasmatec coating and are washable in a thermal disinfector and sterilizable up to 135°C, making infection control maintenance easy and convenient.

“The development of the MASTERmatic series came from listening to our customers and responding to their clinical needs. Our doctors wanted a smaller head size and more access, so we brought new and innovative products to market,” said Stephanie Goss, product manager at KaVo. “KaVo now has a complete electric handpiece portfolio for everything that a doctor needs, providing total flexibility for all treatment applications.”
