AMEXORS NiTi Rotary Root Canal Retreatment Files D1-D3 Gutta-Percha Removal
Specifically engineered for endodontic revision procedures, these NiTi rotary retreatment files facilitate the bulk removal of gutta-percha, carrier-based obturators, and paste fillers from the coronal, middle, and apical thirds of the root canal prior to reshaping.

The AMEXORS NiTi Rotary Root Canal Retreatment Files are designed to streamline non-surgical endodontic retreatment by mechanically engaging and augering out existing obturation materials. Constructed from a high-torsion NiTi alloy, the instruments withstand the rotational resistance encountered when penetrating dense gutta-percha and set endodontic sealers.
The system utilizes a staged approach matched to the anatomical zones of the root canal:
Coronal Third Instrument (D1): Features an active cutting tip to facilitate initial penetration into the coronal gutta-percha mass.
Middle & Apical Third Instruments (D2 / D3): Designed with progressively longer working lengths and non-cutting tips to remove residual filling material from the middle and apical regions while following the existing canal pathway.
The flute geometry is angled to draw softened obturation debris coronally toward the orifice, reducing apical extrusion during revision workflows.
