The X Max Gold File is engineered with MaxTech 3.0 NiTi alloy, offering exceptional flexibility and strength for shaping canals with curvatures less than 15°. Its asymmetrical rectangular cross-section and Archimedean spiral movement allow for efficient debris removal while preserving dentin. Designed with a variable taper, it minimizes the shaping sequence without compromising accuracy. Operating in continuous clockwise rotation, the Crown-Down technique begins with SX for straight-line access, followed by the T File to create a smooth glide path. Shaping continues with X1 and X2 to working length, with X3, X4, and X5 available as needed for deeper refinement.
