Use Case # NiTi Files for Straight and Mildly Curved Canals Efficient NiTi file systems for straight to mildly curved canals (<10°). Single-file and reciprocating options optimized for predictable, low-risk anatomy. 66 systems Mildly curved canals are the lowest-risk anatomy for NiTi instrumentation. The systems below favor efficiency: single-file or two-file sequences, reciprocating motion, and conventional or moderately heat-treated alloys can complete shaping quickly with minimal cyclic fatigue stress. Even in low-curvature anatomy, sound technique — apical pressure control, recapitulation, and adequate irrigation — remains the foundation of safe outcomes. ## Matching systems 66 systems [###
