ZenFlex shaping instruments have variable-pitch flute angles that prevent them from threading into canals, provide them with enormous chip space between flutes, and help prevent tip breakage. These sophisticated instruments deliver single-file shapes without transporting canals due to their variable-heat treatment. Customizing heat treatment for each file size produces smaller files with more shape memory to prevent unwinding and larger files with remarkable ductility. It also has a 1mm maximum flute diameter in order to better maintain the structural integrity of teeth after RCT, and Kerr’s AutoFit gutta percha points fit well to the ends of canal shapes cut by ZenFlex Files.”
