Removing Separated Files
Remove broken instruments with Ultrasonics, safely and predictably.
A separated file will immediately change the level of complexity and involvement of an endodontic case by altering the outcome of cleaning, shaping, and filling of the canal. The use of magnification and ultrasonic instrumentation is an excellent alternative to removing a separated file. The procedure starts with a circumferential reduction of the dentin wall using a diamond coated ultrasonic tip (E4D or E18D). Subsequently, a plain tip (E5 or E18) must be placed in contact with the separated file and then activated. The vibration will loosen and dislodge the file.
1. Reduce the dentin wall around the separated file.
2. Vibrate the separated file until it moves.
3. Repeat step 2 until the separate file is removed.
