Manufactured from Nickel-Titanium alloy with Controlled Memory (CM) heat treatment, HyFlex CM files are extremely flexible and more resistant to cyclical fatigue. Therefore the files can 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 to avoid the creation of steps. This form adaptation can be reversed quickly by heat treatment returning the instruments back to their original shape. Visual control after thermal treatment provides the opportunity to varify safe continuation of file use.
For drying and filling, the successful HyFlex CM system also offers paper and gutta-percha points ideally matched to the proven nickel-titanium files.

• Fracture resistance and higher flexibility due to Controlled Memory technology
• Preparation following the canal anatomy
• Fast preparation with high cutting efficiency and reduced number of files Regeneration and visual monitoring for safe multiple use
• Simple single length protocol
• Suitable for almost all clinical cases
