Removal of fractured instruments using a combined automated/ultrasonic technique.
Removal of fractured instruments is one of the most difficult operative procedures in endodontics. Although a number of different devices and techniques have been developed, none are successful in all cases. An additional technique using an automated device (Canal Finder System) for bypassing and an ultrasonic device for loosening and retrieval of fractured instruments is presented. The rationale for this technique is described and illustrated by two clinical cases.
