- 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
- Used to optimize the molecular phase and properties of nickel titanium (NiTi)
- 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
- 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 blanks
- Twisted files can withstand approximately 60% more torque than files made using a traditional manufacturing process
- Recent study showed that Twisted File is up to 70% more flexible than the other NiTi files tested
