The AMEXORS Superelastic NiTi Rotary Files provide a foundational crown-down rotary system for routine endodontic instrumentation in straight to moderately curved root canals. Manufactured from medical-grade austenitic Nickel-Titanium alloy, these instruments offer consistent elastic recovery and torsional rigidity for efficient coronal flaring and dentin removal.
The universal 6-file sequence separates canal preparation into distinct anatomical phases: SX flares the coronal orifice to establish straight-line access; S1 and S2 prepare the coronal and middle thirds using progressive tapers; and F1, F2, and F3 finish the apical third to match corresponding gutta-percha points. With working lengths spanning 17mm to 31mm, this series serves as a cost-effective core inventory item for dental distributors supplying general dental clinics.
