Respecting the Natural Morphology

• The Self-Adjusting File (SAF) adapts to the root canal’s natural anatomy.
• Shaping by vertical scrubbing (5000 vibrations per minute), with simultaneous agitated irrigation.
• Only 2 minutes of shaping, cleaning and agitation.

Minimally-invasive Preservation of Sound Dentin

• Extremely flexible and compressible lattice-like structure.
• Does not impose its shape, but adapts to the canal’s natural morphology circumferentially and longitudinally.
• Retains the long axis of the canal in its original position and avoids creation of “danger zones”.
• Circumferential removal of a uniform layer of dentin, while preserving as much sound dentin as possible.
