As a dental instrument manufacturer, NSK prioritizes the safety of dental professionals and the patients they treat. To ensure the safety of dental practitioners and their patients, NSK offers comprehensive solutions for infection prevention. NSK's innovative technologies reduce the infection risk caused by contamination and aerosols generated by rotary instruments. NSK also offers thorough reprocessing instructions that are essential to properly maintaining a safe and clean dental environment.
Our proprietary, first-in-class Clean Head System prevents foreign bodies from entering the handpiece, while our advanced Anti-Retraction Valve protects against cross-contamination. NSK provides superior safety with our infection prevention features combined with the world's most technologically advanced, award-winning handpiece design.
The DualDefense™ System is the combination of NSK's unique technologies, Clean Head System and the Anti-Retraction Valve, and provides an effective method to effectively reduce possible internal contamination. The efficiency of the DualDefense™ System has been tested and validated by well known universities, such as the University of Washington, Umeå University in Sweden and National University of Singapore.
Aerosols generated by various types of rotary instruments are one of the potential infection causing risks in dental practices. Our tests show that Electric Micromotors with Contra-Angles produce less aerosols compared to Air Turbines. NSK's Z45L Contra-Angle, which is equipped with an On/Off spray switch, releases even less aerosols when switched 'off' compared to other Contra-Angles. The associated risks of contamination can be reduced significantly by switching off the spray switch.
NSK Aerosol Laser Test
According to our test, Contra-Angles produce significantly less aerosols compared to Air Turbines, reducing infection risks for both patients and dental clinicians.
Speed Increasing Contra-Angle with Patented Spray Switch Function
The world's first two-way 'on/off' spray switch function easily allows the choice between mist or jet spray depending on the procedure. The water jet spray generates significantly less aerosols, reducing the risk of infection in dental practices.
Importance of Appropriate Reprocessing
It is essential to clean and lubricate handpieces as soon as possible after each treatment. Failure to properly maintain the handpieces and other dental devices may cause infection, product failure and overheating leading to burn injuries. Please review the videos below and follow instructions on proper reprocessing of instruments for safe treatment.
