In laboratory stress tests, the Twisted File demonstrates superior flexibility and resistance to breakage. These differences translate to better clinical performance.
TF can withstand significantly more torque than files
made using traditional manufacturing processes.1
Cyclic fatigue testing device consists of a main-frame mobile plastic support, allowing precise and reproducible placement of each instrument inside the artificial canal.2
In a comparison of cyclic bending fatigue, TF performed two to three times better than traditional NiTi files.2
TF is up to 70% more flexible than traditional NiTi files.2
