3-File system
The Twisted File (TF) is the first file to combine 3 unique and proprietary processes to deliver optimal strength and flexibility:


1. R-Phase™ heat treatment technology: TF is produced with Kerr Endodontics´proprietary R-Phase Technology. This patented technology is used to increase file flexibility and resistance to cyclic fatigue.


2. Twisted design, not ground: Twisting helps preserve grain structure and reduces formation of microfractures, making the file even more durable.


3. Strength and flexibility that can be measured: In a torsional stress comparison, Twisted Files absorbed more energy before fracture than ground blanks (1). Twisted files can withstand approximately 60% more torque than files made
using a traditional manufacturing process. One study showed that Twisted Files are up to 70% more flexible than the other NiTi files tested (2).
