Dentsply Sirona is proud to announce the launch of the Purevac HVE System. The Purevac HVE System enhances the line of infection prevention products managed by Dentsply Sirona. It fits our overall mission of stopping the spread of infectious diseases in dental offices worldwide.

High-speed handpieces, ultrasonic scalers, air polishers and air/water syringes produce potentially infectious droplets, splatter and aerosols. It is recommended that dentists should utilize a multi-layered approach in order to minimize the risk of cross-contamination in a dental setting. Using high-volume evacuation (HVE) instead of standard saliva ejectors is an important component to reduce the amount of aerosol. Several studies published show that utilizing HVE can reduce the amount of aerosol by 90%-98%.1

The Purevac® HVE System is designed to provide oral high-volume evacuation, visualization, illumination, and retraction during dental procedures. It consists of the HVE Mirror Tip which is a high-volume evacuation tip with built-in dental mirror This enables a one-handed approach to evacuate the patient’s oral cavity of aerosols, splatter, fluid, and debris, while also providing visibility and illumination to the treatment area.  An HVE Hose Adapter is available and consists of a flexible and lightweight HVE hose connected to a 360-degree swivel for the HVE Mirror Tip.

It offers:

  • Visibility and suction all in one hand
  • Increased safety
    • HVE removes 90% more aerosols generated during ultrasonic scaling compared to a low-volume saliva ejector.1
  • Better visibility
    • Fog-free mirror with continuous suction of fluids and debris.
  • Greater fluid reduction
    • 135% more than a low-volume saliva ejector.
  • Easier maneuverability
    • 69% lighter and 130% more flexible than a standard HVE hose.
    • 5-foot, kink-resistant hose with 360° swivel connection for HVE Mirror Tip.
  • Reduced noise
    • 14% less than a standard HVE tip.
    • 5% less than a low-volume saliva ejector.
