What is transseptal fiberotomy surgery?

The supraosseous connective tissue attachment is surgically severed around the involved teeth. Where there are adjacent teeth, the transseptal fiberotomy of a single tooth will involve a minimum of three teeth. Since the incisions are within the gingival sulcus and tissue and the root surface is not instrumented, this procedure heals by the reunion of connective tissue with the root surface on which viable periodontal tissue is present (reattachment).
