Sybron Endo Twisted Files 4% & 6%

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.

Proven performance 
TF has been proven to be stronger and more flexible than other rotary NiTi files in multiple laboratory
comparisons:

• 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
  manufacturing process.
