Trephines, Dental, Endodontic File/Silver Point Recovery
Definition : Dental trephines designed to cut and remove minimal circular sections of the tooth structure immediately adjacent to the metal fragment of a broken file or silver point in a root canal, permitting the fragment to be grasped by an extractor. These instruments are typically hollow cylinders with a very thin circular-saw-like edge and a powered (e.g., electric) low-speed rotary surgical handpiece; endodontic trephines usually provide internal irrigation. Implant removal dental trephines are used to facilitate the extraction of metal fragments from a root canal during endodontic procedures.
