Reverse pull headgear is used in Class III cases with maxillary insufficiency. Simply adjust the arms of the facemask to fit the patient's head, being conscious of the level of the attachment screws to the occlusal plane. Connect one or two six ounce 3/8" elastics (Rhinos) from the upper first molar bands to the attachment screws. The line of force is usually adjusted to be below the occlusal plane. The elastic force and the headstrap hold the facemask in place.
