The X Max File is crafted from advanced MaxTech NiTi alloy, offering a perfect balance of strength and flexibility for shaping regular root canals. Featuring an asymmetrical rectangular cross-section and Archimedean spiral movement, it enables efficient debris removal while preserving dentin. Its variable taper design minimizes the shaping sequence without compromising accuracy. Operating in continuous clockwise rotation, the Crown-Down sequence begins with SX for straight-line access, followed by the T File to establish a smooth glide path. Shaping proceeds with X1 to working length, with X2 for refinement. If needed, X3, X4, or X5 complete the preparation with precision.
