Kerr SybronEndo TF™ Refill (23mm)

• 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.
• 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.
• TF has been proven to be stronger and more flexible than other rotary NiTi files in multiple laboratory comparisons.
• Available in file lengths (23mm)

3-File System

TF™ (Twisted File) is the first and only file to employ unique and proprietary production technology that achieves unrivalled strength combined with flexibility.

R-Phase™ thermal treatment technology optimises the properties of NiTi files to give 70 % more flexibility and 2-3 times more resistance to cyclic fatigue than any other rotating file. 

Being drilled rather than ground optimises the surface structure of NiTi, thus avoiding the accumulation of micro fractures. This process makes the file stronger; other endodontic files have cutting angles that are incorporated through grinding or milling, which damages the integrity of the metal and can lead to file breakage.

The advanced surface conditioning of the TF completes the surface treatment while respecting the integrity of the underlying grain structure. Tests have demonstrated greater strength of the files.
