The image displays the Coltene HyFlex™ Remover, a specialized rotary instrument designed specifically for endodontic retreatment. It is engineered to remove old filling material (Gutta-percha) from the root canal efficiently without the need for chemical solvents.

• Mechanical Gutta-percha Removal: Designed to eliminate the need for chemical solvents, which can be messy and leave residue.

• Non-Cutting Tip: The tip is designed to be minimally invasive, reducing the risk of canal transportation or ledging during the removal process.

• Single File Retreatment: In many cases, this single file can remove the bulk of the filling material, streamlining the workflow.

• Optimal Flexibility: Maintains the high standard of NiTi flexibility to follow the existing canal curvature established during the initial treatment.

• Efficiency: Features a cross-section and flute design optimized for debris evacuation.

The HyFlex Remover is a high-performance Nickel-Titanium (NiTi) file that serves as the first step in a retreatment procedure. Unlike standard shaping files, it is designed to "drill" into and mechanically engage with cured Gutta-percha, pulling it out of the canal quickly while preserving the underlying tooth structure.

• Material: Nickel-Titanium (NiTi).

• Tip Size: ISO 30.

• Taper: .07.

• Length: Typically 19mm or 23mm (working part length is optimized for the coronal and middle thirds).

• Rotation: Constant clockwise rotation.

• Recommended Speed: 400–800 RPM.

• Recommended Torque: up to 2.5 N·cm.

• Entry: Place the HyFlex Remover at the entrance of the canal filled with Gutta-percha.

• Motion: Apply gentle apical pressure. Use a constant rotation and allow the file to engage the material.

• Extraction: The file will pull the Gutta-percha coronally. Remove the file frequently to clean the flutes.

• Completion: Once the coronal and middle thirds are clear, proceed with standard shaping files (like HyFlex CM or EDM) to reach the full working length.

• Irrigation: Use copious irrigation to flush out any remaining small fragments of sealer or Gutta-percha.

• Pack Size: Sold in a Pack of 3 blister cards.

• Identification: Clear labeling on the box indicating "Retreatment" and "Remover" to distinguish it from shaping files.

• Sterilization: The product is typically provided non-sterile and must be autoclaved (134°C) before its first clinical use.

• Single-Use Logic: Due to the high stress placed on the metal when removing hardened Gutta-percha, it is highly recommended to treat these as single-use to prevent instrument separation.

• Warranty: Coltene provides a standard manufacturer's warranty against defects in materials and workmanship. The warranty is voided if the file is used at incorrect torque/speed settings or used beyond its recommended lifespan.
