Reducing Aerosols with NSK Electric Handpieces

Posted: 11th May 2023

“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.

Spray air contributes significantly to spray mist in dental handpieces. Speed increasing handpieces produce less aerosols compared to turbines, to reduce aerosols further, the Ti-Max Z95L has now been fitted with an innovative feature that allows you to switch between a traditional water/air mix and a water jet only. This feature is unique to NSK on Ti-Max Z95L & Z45L models.

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.
