The present system for biomechanical endodontic preparation uses an electro-electronic piece of equipment commanded by software, based on the principle whereby the mechanical forces determining the fracture of the file are monitored by an electronic circuit of great precision to detect the existence of a force equal to or greater than the one determined by the system, and interrupt its operation prior to the actual risk of file fracture, developed to monitor the forces applied to the file being used, within the sequence of sectored cutting, as appropriate for the work, controlling the torque applied to said files, thus avoiding their rupture.
