(A) The open-window approach for retrieving the root is indicated when buccocrestal bone must be maintained. The three-cornered flap is reflected to expose the area overlying the apex of the root fragment being recovered. (B) A burr is used to uncover the apex of the root and to allow sufficient access for the insertion of the straight elevator. (C) The small straight elevator is then used to displace the tooth out of the tooth socket.
