RECIPROC MOTOR-DRIVEN FILE WITH MEMORY (ERC25405025) (Motor-driven file for chemo-mechanical widening of the root canal). This innovative system has the following special features. The S-shaped cutting tip cross-section allows for smooth and atraumatic widening of the root canal. The simultaneous widening and opening function is due to the 150-degree counter-clockwise and 30-degree clockwise semi-rotation, allowing for smooth and unobstructed widening. The semi-rotational movement allows for easy removal of debris from the root canal. The thermal treatment of the NiTi alloy provides a very high elastic limit and resistance to repeated firing cycles.
