Know Your Handpiece

The SonicFill Handpiece is air-driven and connects to dental units using a MULTIflex compatible coupling. The recommended operating pressure range is from 36-50 psi. The dispensing rate is selected by turning the regulating ring at the base of the handpiece. The dispensing rate range 1 through 5 only affects the flow rate of the composite - it does not change the composite viscosity.


Cleaning and Maintenance

The SonicFill Handpiece requires basic maintenance that includes cleaning after each use and a lubrication spray (such as the SonicFill Handpiece Lubrication Spray) once per week.

  • Automated cleaners, such as the QuattroCare™ can be used or it can be manually cleaned between uses. Automated cleaners from other manufacturers will work as well – see the Handpiece Directions for Use for more information.
  • The SonicFill Handpiece Lubrication Spray is available through all authorized Kerr™ dealers and should be used once weekly. The handpiece can be disinfected and sterilized like any other handpiece. However, it should never be submerged in cleaning (such as an ultrasonic bath) or sterilization fluid.


This version seems to polish much better than previous versions.
Dr. Peter Stickney, Ocala, FL
It was an improvement on an already great material! This material was easier to handle than the regular SonicFill 2.
Dr. James Olsen, Ann Arbor, MI
I love your product. I have been using SonicFill for years. I won’t use anything else.
Dr. Bricanei Dyer, St. George, UT
I think this product [SonicFill 3] is far superior to the last version, SonicFill 2. It appears more dense... much better handling!
Dr. Joseph O’leary, North East, PA
Extrusion and consistency of composite was far superior to previous SonicFill 2.
Dr. Ben McCormely, North Huntingdon, PA

Why is the SonicFill 3 Intro Kit pricing very different than SonicFill 2 Intro Kit?

The Intro Kit is an ideal way to introduce customers to SonicFill 3, and the price point is intended to remove any problems converting a customer that may hesitate at the cost of getting started. We win when we sell refills andwant to take down as many barriers as possible to do so. Also, now that KaVo Kerr operates as one company, delivering quality and value for our customers, we can pass on lowered production costs for the handpiece and thecoupler to our customers.

Why does SonicFill 3 packaging look different?

SonicFill 3 is the first Restorative product to use the KaVo Kerr branding that you see today at our trade shows, our business cards, and elsewhere throughout the company. Providing a singular brand enforces the Power of One andhelps communicate the breadth of products that we offer as a company. Going forward, new Restorative productswill follow the KaVo Kerr brand design.

I can’t find the IFU in the new SonicFill 3 Refill boxes?

The SonicFill 3 IFU is now available in digital format on our website (www.kerrdental.com/kerr-restoratives/sonicfill-3-single-fill-composite-system). You will find aninsert card in the Unidose Refill boxes directing users to this link. Users can also review or download additional content such as case studies and training videos. The insert card also provides information on registration for theKaVo Kerr Preferred program.
