Twisted File enables you to shape ideal paths and is flexible enough to work more accurately in curved canals. Twisted File significantly lowers the number of files used per endo case. It reduces chair time for patients and greatly lowers the level and cost of file inventory.
The Twisted File is the first and only file to combine three unique and proprietary processes to deliver optimal strength and flexibility:
R-PHASE™ HEAT TREATMENT TECHNOLOGY
TF is produced with Kerr Endodontics proprietary R-Phase Technology. This patented technology is used to optimize the molecular phase and properties of nickel titanium (NiTi). R-Phase increases file flexibility and resistance to cyclic fatigue.
TWISTED DESIGN, NOT GROUND
Twisting helps preserve grain structure and reduces formation of microfractures, making the file even more durable. Other endodontic files are made by grinding flutes into the file. Grinding weakens the metal’s structure at the molecular level and creates microfractures on the metal’s surface – both of which can lead to file separation.
STRENGTH AND FLEXIBILITY THAT CAN BE MEASURED
In a torsional stress comparison, Twisted Files absorbed more energy before fracture than ground blanks1. Twisted files can withstand approximately 60% more torque than files made using a traditional manufacturing process. A recent study showed that Twisted File is up to 70% more flexible than the other NiTi files tested2.
