Clinical Tips

Same motor settings for all files: 300 RPM, 2.5 Ncm

C.Wire controlled-memory alloy allows pre-bending for difficult access

Variable cross-section: triple helix at tip for centering, S-shaped coronally for debris removal

Single-file system: one instrument shapes the full canal in most cases

No sucking-in effect during use — smooth cutting action

Mini variant available with smaller 1mm wire diameter for restricted access

Compatible with One Flare (coronal flaring) and One G (glide path) ecosystem

Warnings

  • Single-use only — sterile, pre-packaged, do not reprocess
  • Contains nickel — do not use on patients with nickel allergy
  • Always establish glide path before rotary shaping
  • Inspect for deformation before use — discard if any signs of damage
  • Do not leave file rotating at working length for extended periods
  • Not recommended for severely calcified canals without prior negotiation
