The SAF is a hollow file designed as an elastically compressible, thin-walled pointed cylinder that is composed of a nickel-titanium lattice. It is used as a single instrument to achieve complete 3D root canal cleaning and shaping in a minimally invasive way. Its hollow shape allows for the continuous flow of irrigant through its lumen to achieve superior disinfection.
The SAF’s main features are:
The SAF is available in three standard lengths (21 mm, 25 mm and 31 mm) and three diameters (1.5 mm, 2.0 mm, 3.0 mm).
The SAF 1.5 mm is designed for canals with an initial apical size of ISO 20-35. It is available in 21mm, 25mm and 31mm length.
The SAF 2.0 mm is designed for use in wider canals with an initial apical size of ISO 35-60 commonly found in retreatments or younger patients. It is avaiable in 21mm, 25mm and 31 mm length.
The SAF 3.0 mm is designed for use in very wide canals, with an initial apical size larger than ISO 60, commonly found in very young patients.
The Self-Adjusting Files are operated by the SAF Infinitum, that provides simultaneous irrigation directly into the file, combined with suction around the shank, to clear the treatment area from debris-carrying excess irrgant.
