HyFlex CM are rotary endodontic files made from nickel-titanium (NiTi) alloy with Controlled Memory technology.
They are designed to follow the natural anatomy of root canals, especially curved or complex canals, while minimizing procedural errors such as ledging, transportation, and perforation.

• Controlled Memory (CM) Technology – No rebound effect, superior flexibility
• Extremely Flexible – Adapts to severe canal curvatures
• High Cyclic Fatigue Resistance – Up to ~300% more than conventional NiTi files
• Pre-bendable – Similar to stainless steel files for better access
• Maintains Canal Anatomy – Reduces risk of procedural errors
• Shape Recovery – Regains original shape after autoclaving
• Visual Safety Control – Deformation indicates when to discard
• Multiple Technique Compatibility – Crown-down, step-back, single-length

• Material: Nickel-Titanium (Controlled Memory Wire)
• Technology: Heat-treated CM alloy
• Lengths Available:
  • 21 mm
  • 25 mm
  • 31 mm
• Taper Options:
  • .04
  • .06
  • .08
• ISO Sizes:
  • 15, 20, 25, 30, 35, 40, 45, 50, 60
• Motion Type: Continuous rotary
• Sterilization: Autoclavable (shape recovery feature)
• Protocol: Single-length or sequence-based

• Standard packaging:
  • Pack of 3 or 6 files (blister pack)
  • Pre-sterilized or non-sterile depending on supplier
• Also available as:
  • File sequences (assorted sizes)
  • Kits for specific procedures

1. Access cavity preparation
2. Establish glide path (hand files recommended)
3. Select appropriate file size & taper
4. Use with torque-controlled endodontic motor
   • Typical speed: ~400–500 RPM (follow IFU)
5. Gentle in-and-out motion (no force)
6. Irrigate frequently (NaOCl/EDTA)
7. Clean flutes after each insertion
8. Inspect file for deformation
9. Autoclave before reuse
10. Discard if file does not regain shape after sterilization
