The AMEXORS Gold Heat-Activated NiTi Rotary Files utilize a post-grinding thermal treatment process that forms a characteristic gold titanium-oxide surface layer. By adjusting the phase transformation temperature of the NiTi wire, the instrument maintains a balanced austenite-martensite metallurgical profile. Compared to conventional superelastic NiTi files, this gold-phase alloy offers controlled memory characteristics and improved resistance to cyclic fatigue when navigating middle and apical third curvatures.
The sequence is organized into three shaping files (SX, S1, S2) with progressive variable tapers for coronal and middle third enlargement, followed by three finishing files (F1, F2, F3) with fixed apical tapers for precise apical preparation. Each instrument features a non-cutting guidance tip to reduce the risk of ledges or perforations, along with depth calibration markings and color-coded silicone stops for working length control.
