COLTENE H8210425 HyFlex CM NiTi File Taper 21mm

The COLTENE H8210425 is a pack of six HyFlex CM nickel-titanium (NiTi) rotary files. These files have a .04 taper and a length of 21mm. HyFlex CM files are manufactured with a heat-treated NiTi alloy that provides controlled memory (CM), resulting in extreme flexibility and increased resistance to cyclic fatigue. This allows the files to closely follow the natural anatomy of the root canal, reducing the risk of ledging, transportation, or perforation. Similar to stainless steel files, HyFlex CM files can be pre-curved, which is particularly helpful in negotiating sharply curved canals and preventing the creation of blockages. The controlled memory property allows the file to return to its original shape after heat sterilization, enabling visual inspection for safe reuse. The HyFlex CM system also includes matching paper points and gutta-percha points for efficient drying and obturation. Key benefits include increased fracture resistance and flexibility, preparation that respects canal anatomy, regeneration and visual control for safe multiple uses, a simple single-length protocol, and a wide range of sizes to cover most clinical cases.
