Advantages of electric driven handpieces over air turbine.

In Dentistry, The handpiece is one of the most basic needs and commonly used dental instruments. The number of applications in endodontics, general dentistry, and implantology requires a comfortable handpiece that works well. Behind every best dental specialist, there is always an incredible dental handpiece with numerous applications in dental procedures.

The air-driven high-speed handpiece is the widely accepted handpiece because it is much cheaper than an electrical handpiece. Electrical Handpiece on the other hand are expensive but due to its air turbine feature, it stands apart from normal air-driven handpieces.


Air-driven dental handpieces utilizes air energy to create a cutting or rotary motion. This technology is well-proven over many years.

There are several advantages of using an air-driven instrument.

Air-driven high-speed handpieces are smaller in head height, lighter in weight, and easy to handle than the electrical handpieces.

Air-driven high-speed handpieces tend to have a higher speed, but a lower torque.  However, when a bur comes into contact with the tooth, it slower down the bur due to resistance builds up. The harder the pressure on the bur, the slower the bur spins.

There are several disadvantages of using the traditional air-driven low-speed handpiece. One major issue is aerosol. It generates lots of aerosols while working in the patient mouth. Nowadays the generation of aerosol is prohibited in the epidemic period of Covid-19. As aerosol may cause cross-contamination of bacteria and viruses.

Also, other issues are the high noise and vibrating sensation of the air motor. However, air-driven low-speed handpieces make a loud whirring noise that disrupts the relaxing environment and disturbance to other patients.


Electrical handpieces operate using an electric motor to create the rotation and cutting motion of the burs. Electric driven handpieces tends to be a little heavier and can increase user fatigue, especially when used for a longer period of time.

There may be a slightly higher risk in the hands of an inexperienced practitioner because there is no “sound-feedback” like that of an air-driven instrument.

Electric high-speed handpieces run at a constant speed and consistent torque that does not decrease with higher load. It also produces a smoother and more precise cutting due to the stable speed which allows high flexibility in preparations.

Some electrical systems allows to control the torque and speed which tends to have additional ENDO & RESTORATIVE preparations.

In the recent scenario, the Covid-19 outbreak has spread in many countries. As dental professionals are at maximum risk due to Covid-19 transmission, the electrical handpiece is quickly picking up ubiquity supplanting conventional air-driven as these electric handpieces generate less aerosol compared to the air-driven high-speed handpieces.

The generation of less aerosol is the major advantage of an Electric high-speed handpiece. Patients also like electric handpieces because they are quieter and Vibration free which creates a relaxing environment. This can help in patients satisfaction which translates to positive reviews online and increased patient retention.

The Optic Light in handpiece always gives better visualization. Nowadays electric motor systems are equipped with LED light which gives further an added advantage.

Conclusion: The electric handpiece provides constant speed, high torque, optimum durability, utmost cutting efficiency with very less noise & thus enables faster cutting & long durability of the handpieces. Now it’s time to upgrade from High-speed Air-driven handpieces to High torque electric drive handpieces.


To start working with an electrical handpiece is allow to get the advantage of two systems.

NSK NLX nano

A new generation of micromotor is well balanced as an air turbine.

NLX nano has been designed to minimize weight and size to improve the balance of instrument and motor in the hand of the clinician, reducing fatigue during prolonged procedures. Despite its small size and lightweight, the NLX nano is as powerful as traditional micromotors and offers a wider range of speeds. Its 180° Vector Control assures smooth and stepless control over the entire speed range. Thanks to LED illumination, it now delivers 32,000 LUX*, natural daylight quality light, and assures clearer vision, reducing fatigue during operation.
