Root removal

A) When the crown of the lower molar is lost because of fracture or caries, the envelope flap is reflected, and a small amount of crestal bone is removed. A burr is then used to section the tooth into two individual roots. (B) After the small straight elevator has been used to mobilize the roots, the Cryer elevator is used to elevate the distal root. The tip of the elevator is placed into the slot prepared by the burr, and the elevator is turned to deliver the root. (C) The opposite member of the paired Cryer elevators is then used to deliver the remaining tooth root with the same type of rotational movement.
