  • Fracture resistant
  • Easy to follow
  • Extremely flexible

HyFlex™ Controlled Memory NiTi Files have been manufactured utilizing a unique process that controls the material’s memory.

FEATURES:

  • 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.

Instructions:

A new file should be used for each procedure to reduce the risk of file separation.

  • Sterilize files prior to use. See sterilization instructions below.
  • Use of a slow speed hand piece required. Operate the hand piece at 300 RPM (revolu- tions per minute). Recommended torque setting up to 2.5 N·cm (25 mN·m).
  • Irrigate during and between each step. COLTENE® ENDO recommends the use of CanalPro™ EXTRA for irrigation and debridement.
  • Clean file flutes after each insertion into the root canal.
  • Recapitulate between each step.

 

Files may be used with Crown-down and Step-back techniques, or with the Hybrid technique below. In curved canals, use of a HyFlex® CM™ (Controlled Memory) is recommended for preparing the apical curvature.

 

Step by Step instructions:

 

Coronal Patency: After gaining a Straight-Line coronal access, create an apical glide path using HyFlex® GPF™ system or a 02/20 hand file size.

 

STEP 1 - Start with the 08/25 file. Use as an orifice opener. Move slowly forward without pressure in a pecking motion. Once resistance occurs go to step 2. Check patency with 02/20 hand file, irrigate and lubricate. Optional Step: If working length is reached in large canals it may be possible to go directly to step 4.

STEP 2 - Use the 04/20 file for apical enlargement to the Working Length. Move slowly forward without pressure in a pecking motion. In case resistance occurs use a 02/20 hand file to check patency. Irrigate and lubricate.

STEP 3 - Insert 04/25 file for apical enlargement to the Working Length. Move slowly forward without pressure in a pecking motion. If resistance occurs, go back to the previous step. Use a 02/20 hand file to check patency. Irrigate and lubricate.

STEP 4 - Use the 06/20 file to shape middle part of the root canal. This file can also be taken to Working Length. Move slowly forward without pressure in a pecking motion. If resistance occurs, go back to the previous step. Use a 02/20 hand file to check patency. Irrigate and lubricate.
