Kerr’s New ZenFlex NiTi Rotary Shaping File Delivers High Cutting Efficiency, Minimally Invasive Design

December 11, 2020

In initial comparison tests, ZenFlex exhibits exceptional performance across a range of metrics including torsional strength and resistance to cyclic fatigue.

Kerr Dental’s new ZenFlexTM NiTi Rotary Shaping File features high cutting efficiency,
an ideal balance of strength and flexibility, and a minimally invasive design. These benefits are made possible due to the proprietary variable heat treatment technology used in ZenFlex, according to the manufacturer.

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.

Through the 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 than 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.*

ZenFlex offers endodontists a minimally invasive shaping file option, with a 1 mm maximum flute diameter and its non-cutting tip. Combined, these features help increase control during the root canal procedure and preserve the tooth's structural integrity.

ZenFlex became available to order in early December. To learn more about the ZenFlex NiTi Shaping File, visit Go.Kerrdental.com/ZenFlex.
