Retrieval technique for fractured implant screws.

Fractured screws generally are challenging to remove. The technique described in this article involves the use of inexpensive instruments commonly found in dental offices. The force required to remove the broken screw is minimal provided that the screw threads have not been damaged previously. A high degree of manual dexterity is required, however, to prevent damage to the implant itself; thus, this may not be the procedure of choice for inexperienced practitioners.
