Introduction: The complex anatomy of root canals, combined with repeated and/or inadequate use of instruments, can lead to their fracture. The aim of this study was to demonstrate through 3 clinical reports a technique of fractured endodontic files removal, in different thirds of the root canal, through the association of hand files and ultrasound. Methods: In these cases, three teeth with fractured files inside the root canals were treated similarly, through the association of manual endodontic files and ultrasound. In all cases, there were an estimated failure due to the size and position of the fragments inside the canal. However, the protocol adopted demonstrated 100% efficacy. Conclusion: The present technique associating manual files and ultrasound was effective, allowing the removal of fractured hand files inside root canals.
