Fig. 1. Drawingshowing the coronally advanced lingual flap procedure at the 1st molar area. (A) Once a full-thickness lingual flap has been elevated up to the mylohyoid line, the attachment of the superficial fibers at the base of the flap can be seen. (B) By gently advancing the flap coronally and lingually, the periosteum at the base of the flap can easily elevated and superficial fiber from the main body of the muscle can be separated with periosteal elevator. (C) This technique allows for a coronal advancement of the flap up to 10 to 15 mm. Modified from the Rossetti.
