The K55 ExtractEZE™ Root Tip Remover (RTR) is a finger tip grip instrument used to extract a root tip. These are ideal for medium-sized canals of the tooth. The working length is considered medium at 19 mm. Its end has an extremely sharp surgical screw tip with each thread designed to be an anchoring, cutting edge which secures into the root’s dentin through a “self-seating” process. The RTR’s fine tip is designed to find and access a small root canal within the limited space and visibility of the patient’s mouth. The instrument is gently rotated clockwise until firmly seated then the extraction process may begin.
