Mandibular advancement appliance. The maxillary and mandibular dental casts were made after the alginate impressions were obtained. The dental arches of both jaws were fabricated by placing a 1-mm thermoforming polyethylene plate on the dental cast using a full pressure dental thermoforming machine. The maxillary and mandibular components were joined by autopolymer resin with the maximum mandibular protrusion tolerated without discomfort or pain.
