SybronEndo introduces new apical sizes of Twisted File, the most advanced endodontic NiTi file on the market. The new apical sizes include: .04 Taper/40 Tip (27 mm); .04 Taper/40 Tip (23 mm); .06 Taper/35 Tip (27 mm); .06 Taper/35 Tip (23 mm); .06 Taper/30 Tip (27 mm); and .06 Taper/30 Tip (23 mm). Twisted Files combine three proprietary processes to deliver unsurpassed strength and flexibility. Using our R-Phase Heat Treatment Technology, TF optimizes the properties of NiTi, making this the most flexible file on the market today. TF cutting flutes are created by twisting the file, not grinding, eliminating micro fractures for greater strength and durability. The advanced surface conditioning treatment finishes the file surface while respecting the underlying grain structure.
