Kerr endodontic file / nickel titanium
K3™ Files Endodontic ShapingK3 Nickel Titanium FilesK3 is a third generation asymmetric endodontic file system. Designed to remove debris quickly, eficiently and safely, K3 addresses technical and procedural issues like no other ground-fluted file.Variable pitchMany files maintain a constant pitch (distance between the cutting edges) throughout the length of the file. This may result in a “screw-in” effect. The K3 file has a varied pitch that effectively transports debris coronally. This is important not only during initial cleaning and preparation but also for revisions.Less friction, more stabilityAlleviating pressure on the cutting edge of the radial surface of K3 files minimises frictional resistance. Other NiTi systems have wide radial lands that increase friction and can lead to breakage.K3 files have added mass to the cutting surface to provide greater support to prevent deformation. With other systems, blade rollover or cracks can occur during instrumentation.
