HyFlex™ CM NiTi Files
Root Canal Shaping
Like a Phoenix from the ashes... the regenerative NiTi File!
No shape memory + Extreme flexibility = Superior canal tracking
HyFlex™ Controlled Memory NiTi Files have been manufactured utilizing a unique process that controls the material's memory.
The files are extremely flexible but without the shape memory of conventional NiTi Files.
This gives the file the ability to follow the anatomy of the canal very closely, reducing the risk of ledging, transportation or perforation.
Furthermore the files can be pre-bent, similar to the way of stainless steel.
Particularly in root canals with abrupt curvatures this can help avoid the creation of steps.
Regains shape after heat treatment = Multi-use
HyFlex™ CM NiTi files respond to excessive resistance with straightening of the spirals, which avoids binding to the walls and therefore increases fracture resistance.
This form adaptation can be reversed quickly by heat treatment (during autoclaving or with a glass bead sterilizer) returning the instruments back to their original shape.
Furthermore it will strengthen the files making them a lot more resistant to cyclical fatigue.
Also it provides a clear visual opportunity to verify safe continuation of file use.
HyFlex™ EDM NiTi Files
Root Canal Shaping
The new HyFlex EDM files constitute the 5th generation root canal files. HyFlex EDM NiTi files have completely new properties due to their innovative manufacturing process using electric discharge machining.
Workpieces are machined in the EDM manufacturing process by generating a potential between the workpiece and the tool. The sparks generated in this process cause the surface of the material to melt and evaporate. This creates the unique surface of the new NiTi files and makes the HyFlex EDM files stronger and more fracture resistant. This entirely unique combination of flexibility and fracture resistance makes it possible to reduce the number of files required for cleaning and shaping during root canal treatments without having to compromise preservation of the root canal anatomy.
Just like HyFlex CM files, HyFlex EDM files have the already familiar controlled memory effect (CM). This results in very similar properties in terms of material flexibility and regeneration.
