It’s time to switch - Go Electric with NSK

“Careful operation of dental drills can minimise the aerosol spread of COVID-19”

As practices strive to get their services back to as close to normal as they can in the current climate, the issues around aerosol generating procedures and reducing fallow time continue to be prime considerations for dental professionals.

Along with new decontamination processes and PPE measures, having to leave long intervals between treatments to allow aerosols to dissipate have dramatically reduced the number of patients that can be treated in a single day.

Now, researchers at Imperial College London and King’s College London have been analysing and measuring aerosol generation during dental procedures. Read more about their suggested methods to prevent initial contamination and how to improve safety for both patients and the dental team here.

The benefits of going electric

Electric driven speed increasing handpieces (1:5) produce less aerosols compared to high-speed turbines. Speed increasing contra-angles not only do everything a turbine does using the same FG burs, they provide a consistent torque from the micromotor that does not decrease with resistance and higher load with no loss of power as they come in contact with the tooth.

Electrically driven instruments are well-known for their flexible functionality and for operating at vastly reduced noise levels with reduced vibration for added patient comfort. Thanks to the torque control they provide a smooth and more precise cutting action that is generally considered to be superior to that provided by an air rotor.

The need for a speed increasing contra-angle, in combination with an electric micromotor, should not be underestimated for precise tooth preparation. The combination of a speed increasing contra-angle and micromotor gives me complete speed control, improved tactile sensation, and a smoother running bur than a turbine. All of these advantages equate to more precise margins and potential for improved overall clinical results.

We do a lot of close magnification work in practice and I find the Ti-Max Z95L operates with very little vibration and delivers of level of control not replicable with a turbine.

Easy integration

Electric micromotors can be fully integrated into the delivery system of most new and existing dental treatment chairs. They can be retro fitted by an engineer or come as an option when buying new chairs. Controlling the specific speed and torque of micromotors within existing platforms is made easy thanks to built-in control pads.

The way forward

The risk of aerosol generation is paramount in clinicians’ minds. Spray air contributes significantly to spray mist in dental handpieces, but clinicians need to know there is a significant way forward with the NSK Ti-Max Z95L and Ti-Max Z45L speed increasing contra-angles.

Speed increasing handpieces generate less aerosols compared to high-speed turbines. To reduce aerosols further the Ti-Max Z95L and Ti-Max Z45L are fitted with the world’s first two-way spray technology unique to NSK allowing clinicians to switch between a water/air mix and water jet only with just a twist of the switch. Plus they have the additional benefit of a non-retraction valve that prevents suckback/contamination of the water line.

When extra safety is needed the water jet provides maximum protection while still offering optimum cooling, then when conditions allow switching back to mist is simple. No equipment modification is needed, putting control back in clinicians’ hands.

Options for Ti-Max speed increasing handpieces

  • Mist to water jet switch
  • Lightweight titanium outer casing
  • Narrower neck and body
  • 4 hole spray
  • Option of 45° angled head (Z45L)
  • 3 year warranty covering service and repairs
Water jet or mist spray
NSK Ti-Max Z95L

The Ti-Max Z95L is perfect as the design offers improved visibility through the reduction of head and neck size and runs with almost no vibration.
