Twisted Files (TF) combines three proprietary processes to deliver unsurpassed strength and flexibility. Using our R-Phase heat treatment technology, TF optimizes the strength and flexibility of NiTi, creating a highly durable and flexible file. TF cutting flutes are created by twisting the file, not grinding, eliminating micro fractures for greater strength. The advanced surface conditioning treatment finishes the twisted file surface while respecting the underlying grain structure. The result is a rotary NiTi endo file strong enough to cut ideal file paths confidently, yet flexible enough to do it efficiently. Dentists and Endodontists alike are discovering that with Twisted Files they are able to shape root canals safer, faster, more efficiently and with fewer files.
Advanced design and manufacturing TF® by SybronEndo is the first and only file to combine unique and proprietary manufacturing processes to deliver unsurpassed strength and flexibility.
R-Phase™ heat treatment technology
This proprietary technology optimizes
the metalurgy of NiTi files making them 70% more flexible and 2-3 times more
resistant to cyclic fatigue than other rotary files.
Twisted, not ground
Twisting optimizes NiTi grain structure and eliminates formation of microfractures, making the file even more durable.
Other endodontic files are made by grinding flutes into the file, weakening the metal’s structure which can lead to file separation.
Advanced surface treatment
TF’s special surface conditioning treatment finishes the file surface while respecting the integrity of the underlying grain structure.
Tests show that this conditioning treatment increases the hardness of the file.
TF has been proven to be stronger and more flexible than other rotary NiTi files in multiple laboratory
In a study of cyclic fatigue, TF performed two to three times better than traditional rotary NiTi files,
and significantly better than ProFile GTX.
In a torsional stress comparison, TF was shown to absorb the greatest amount of energy before
fracture by far. In fact, it can withstand about 60% more torque than files made using a traditional
