MOTORIZED RECIPROC FILE WITH MEMORY (ERC25405025) (Motorized chemomechanical root canal enlargement file). ¨ This innovative system has the following special features. ¨ The S-shaped cutting tip allows smooth and atraumatic enlargement of the root canal. ¨ The simultaneous enlargement and opening function is due to the 150-degree counter-clockwise and 30-degree clockwise semi-rotation, allowing smooth and unobstructed enlargement. ¨ The semi-rotational movement allows easy removal of debris from the root canal. ¨ The heat treatment of the NiTi alloy provides a very high elastic limit and resistance to repeated firing cycles.
