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.
