The X Max Blue File is constructed from MaxTech 6.0 NiTi alloy, offering enhanced flexibility and pre-shaping capability—ideal for canals with curvatures between 15° and 35°. Its asymmetrical rectangular cross-section and Archimedean spiral movement enable efficient debris removal while maintaining canal integrity. Designed with a variable taper, it reduces the number of shaping steps while ensuring precise and conservative preparation. Following a Crown-Down approach, the sequence begins with SX for straight-line access, T File for glide path creation, then X1 to working length. Shaping continues with X2, and if required, progresses to X3, X4, and X5 for complete refinement.
