Coltene HyFlex NiTi Endodontic Files 21 mm – 4% Taper

HyFlex™ Controlled Memory NiTi endodontic files are designed with a unique manufacturing process that controls the material’s memory. These HyFlex CM files provide flexibility and precision, making them compatible with crown-down, step-back, or recommended single-length techniques. This ensures efficient root canal preparation with enhanced safety.

300% More Resistance to Separation
HyFlex CM NiTi endodontic files with controlled memory offer up to 300% higher resistance to cyclical fatigue compared to traditional NiTi files. This increased durability significantly lowers the chance of file separation during clinical use, providing more reliable performance for practitioners.

No Rebound + Extreme Flexibility = Superior Canal Tracking
These NiTi endodontic files are manufactured with a special process that eliminates shape memory while enhancing flexibility. The result is a file that closely follows the anatomy of the canal. This reduces risks associated with ledging, transportation, or perforation, ultimately improving treatment outcomes.

Regains Shape After Sterilization = Multi-Use
The shape and strength of HyFlex CM files with their straightened spirals can be restored during autoclaving. This controlled shape memory enables the files to be reused multiple times, improving cost-effectiveness. However, any file that does not regain its shape after sterilization must be discarded to ensure safety.

Features of HyFlex CM NiTi Endodontic Files

• Constructed from regenerative Titanium Nickel, providing strength and durability.
• Delivered pre-sterilized for immediate clinical use.
• Exhibits far greater resistance to cyclic fatigue than conventional NiTi files.
• Demonstrates a low incidence of file fracture, enhancing patient safety.
• The design follows the natural anatomy of the canal, minimizing the risk of procedural errors such as steps, displacements, or perforations.
• Offers extreme flexibility combined with excellent break resistance.
• Features long life expectancy, thanks to the integrated controlled shape memory that restores form after autoclaving.

Directions To Use

Preparation:

• Ensure proper isolation of the operating field before starting.
• Confirm that files are pre-sterilized and ready to use.

Instrumentation Technique:

• Select the file size appropriate for the canal anatomy to ensure precise treatment.
• Use the crown-down, step-back, or recommended single-length technique based on case requirements and preference.

Handling and Technique:

• Maintain a firm yet gentle grip on the file for better control during instrumentation.
• Carefully introduce the file into the canal, proceeding gradually.
• Follow the natural canal anatomy closely to minimize procedural errors like perforations or displacements.

Flexibility and Canal Tracking with NiTi Endodontic Files

• HyFlex CM NiTi files offer extreme flexibility, enhancing canal tracking accuracy.
• The controlled memory technology enables these files to adapt closely to the canal's shape.
• This flexibility reduces the chances of ledging, transportation, or canal perforation.

Autoclaving and Reuse

• After use, the files should be cleaned and sterilized properly using an autoclave.
• The controlled shape memory allows these files to regain their original shape post heat treatment, making them reusable.
• Always discard any file that fails to return to its initial shape to maintain safety standards.

Size and Taper Selection

• Select file sizes and tapers specifically suited to each case requirement.
• Sizes range from 15, 20, 25, 30, 35, to 40, all with a 4% taper and length of 21mm.

Safety Measures for Using NiTi Endodontic Files

• Avoid applying excessive force during instrumentation to lessen the risk of file separation.
• Regularly inspect the files during treatment and replace any showing signs of deformation or inefficiency.
