Abstract

Various modes of resistance welding between steel and Ni-Ti-extracting electrodes and fractures of endodontic files were investigated. It was demonstrated that in close to real clinical situations there is most suitable a sequence of a number of pulses of a steepened welding current. As a result, detachment force limit of 15-50 N is achievable which is sufficient for the fracture extraction in most cases.
