Conventional rotary files follow a predetermined shape. As a result, in complex root canal systems, not all areas of the canal are reached and cleaned equally. In addition, mechanical preparation and chemical cleaning are typically performed as separate steps.
The Self-Adjusting File (SAF) takes a fundamentally different approach: instead of adapting the canal to the file and unnecessarily removing tooth structure, the file adapts itself to the individual anatomy of the root canal. Thanks to its three-dimensional lattice design, it enables preparation with continuous irrigation and sonic activation throughout the entire treatment process.
The result is a minimally invasive preparation that respects the natural canal anatomy while combining mechanical preparation and chemical cleaning in a single integrated workflow.
