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.
