• Stiff, Effective Tip: Unlike standard shaping files, these are designed to engage and "drill" into hardened filling materials effectively.

• Sequential Clearing: The system uses three distinct files specifically sized for different sections of the canal to ensure complete evacuation.

• High Cutting Efficiency: The flute design is optimized to pull debris coronally (outward), preventing the material from being pushed through the apex.

• Mechanical Removal: Designed to minimize the need for chemical softeners, leading to a cleaner canal and faster workflow.

The Kinetic Re-Treatment File is a specialized rotary system designed specifically for the removal of filling materials (such as Gutta-percha, carrier-based obturators, or paste) during endodontic retreatment procedures. These files feature a unique design with varying lengths and tapers to efficiently clear the coronal, middle, and apical thirds of the root canal without the heavy use of chemical solvents.

The system typically consists of three files:

1. D1 (30/08): 16mm length – for the Coronal third removal.

2. D2 (25/08): 18mm length – for the Middle third removal.

3. D3 (20/07): 22mm length – for the Apical third removal.

• Material: Nickel-Titanium (NiTi).

• Speed: 500–700 RPM.

• Torque: 2.0–3.0 N·cm.

• Orifice Access: Start with the D1 (Blue) file to remove material from the canal entrance.

• Progression: Use D2 (Red) to reach the mid-section, followed by D3 (Yellow) to reach the apical third or full working length.

• Motion: Use a gentle "touch-and-withdraw" motion. Do not force the file apically; let the flutes engage and pull the material up.

• Completion: Once the old material is removed, switch to standard shaping files (like Kinetic Flex) to finish the canal preparation.

• Blister Pack: Contains 6 files per blister.

• Assorted: Packs usually contain 2 of each size (D1, D2, D3).

• Individual: Packs containing 6 of a single size.

• Sterilization: Must be autoclaved at 134°C before use.

• Safety: Due to the high stress of removing hardened material, these files should be discarded if any deformation or "unwinding" is observed.

• Single-Use: Recommended for single-patient use to ensure maximum strength and prevent cross-contamination.

• Guarantee: Guaranteed against manufacturing and material defects upon arrival.

• Limitations: Warranty is void if files are used beyond recommended RPM/Torque settings or if used in canals where calcification prevents mechanical engagement.
