AMEXORS Gold And Blue Hybrid Heat-Treated NiTi Rotary Files SX-F3 Sequence

Different thirds of the root canal impose distinct mechanical demands on rotary instruments: coronal and middle flaring requires torsional stiffness and cutting efficiency to remove restrictive dentin triangles, whereas apical finishing demands high flexibility to follow delicate terminal curvatures. The AMEXORS Gold and Blue Hybrid Heat-Treated NiTi Rotary Files address both requirements within a single coordinated sequence.

In this hybrid system, the coronal/middle shaping instruments utilize gold-phase thermal treatment to provide firm tactile control and efficient brushing action. The larger-diameter finishing files utilize blue-phase martensitic heat treatment to maximize cyclic fatigue resistance and minimize restoring force as they negotiate the apical third. This dual-metallurgy configuration eliminates the need for clinics to purchase separate Gold and Blue packs to customize their clinical workflow.
