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

8/8/2019 428792_634135552846493750


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

The SAF is extremely flexible and pliable.

It does not impose its shape on the canal but rathercomplies 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
