SAF Mode of ActionSAF Mode of Action

Roughness : 2.8 µm ± 10%

1. Abrasive surface

The hollow design enables the SAF to be elastically compressed along its cross section (A) when inserted into a canal

previously negotiated with a no. 20 K file (B).

2. Compression

Attempting to expand, the SAF applies light continuous pressure along the entire circumference of the root canal wall.

3. Gradual Expansion

Operated with a gentle vertical vibration 5,000 strokes per minute, the file Operated with a gentle vertical vibration 5,000 strokes per minute, the file achieves a gradual enlargement of the root canalachieves a gradual enlargement of the root canal

4. Repeated Motion

0.4

mm

The SAF is extremely flexible and pliable.

It does not impose its shape on the canal but rather complies with the canal’s original shape.

This is true both longitudinally (A)

and circumferentially (B).

The long axis of the canal is kept at it’s original

place throughout the length of the canal
