Abstract
Provided is a system for endodontic treatment of a root canal. The system includes a handpiece containing a rotary motor adapted to rotate an endodontic file secured by the handpiece. A control unit executes a regime of motion of the motor to produce a regime of file motion in which episodes of oscillation of the file are separated by a rotation of the file. When the arc of a rotation is less than the arc of the oscillation that preceded the rotation, the arcs of the episodes of oscillation overlap and the formation of ridges in the root canal is avoided.
Claims11
A system for endodontic treatment, comprising:
- (a) a handpiece containing a rotary motor adapted to rotate an endodontic file secured by the handpiece;
- (b) a processor configured to execute a regime of motion of the motor or produce a regime of file motion comprising:
- (c) for k=1 to n, where n is an integer;
- (i) oscillating the file through an arc αk at a frequency of oscillation fk for an amount of time Tk or a number of oscillation cycles Mk;
- and
- (ii) rotating the file either clockwise or counterclockwise through an arc βk.
