Kerr Launches ZenFlex™ NiTi Rotary Shaping File with High Cutting Efficiency and Minimally Invasive Design

Brea, CA (12/7/2020) — Leading innovator of endodontics technology, Kerr Dental, announces the launch of the ZenFlex^TM NiTi Rotary Shaping File, featuring high cutting efficiency, an ideal balance of strength and flexibility, and a minimally invasive design. Initial comparative studies against other leading files on the market indicate that ZenFlex delivers exceptional resistance to torsional stress and cyclic fatigue, while offering the flexibility and controlled memory to accommodate even the most complex canal anatomies.

“We’ve designed ZenFlex to balance strength with flexibility, as well as achieve high cutting efficiency, all while being minimally invasive,” says Lea Pagaduan, Marketing Manager at Kerr Dental. “These are made possible due to the proprietary variable heat treatment technology used in ZenFlex.”

Through this heat treat process, ZenFlex provides the strength and flexibility to accommodate up to 90-degree curves. ZenFlex additionally has exceptional controlled memory to maintain its pre-curved shape to better follow even then most challenging canal anatomies.

In recent comparative tests, ZenFlex delivered greater resistance to cyclic fatigue than other files, resulting in a longer time to failure. Additional tests showed that ZenFlex is as resistant or more resistant to torsional stresses despite having a smaller maximum flute diameter and smaller mass.  

“In tests conducted by leading endodontist Dr. Stephen L. Buchanan, against other recognized files on the market, ZenFlex did a better job reaching the full working length of severely curved canals,” explains Brian Ho, Kerr Dental Global Product Manager.
