Definition : Trephines designed to cut and remove circular sections of tissue during dental procedures. These instruments are typically hollow, cylindrical, detachable blades with a circular-saw-like edge and a manua or, more frequently, powered (e.g., electric) rotory surgical handpiece. Dedicated dental trephines are available to facilitate the retrieval of broken files and silver points from root canals, for artificial tooth root implantation, and for removal of failed implants.
