Abstract
Abstract An orthodontic appliance comprising a bar that provides a splint for setting broken jaws or other facial bones. Upper and lower bars are attached to the patient's teeth with ligature wires and interconnected with the elastic bands to allow the jaw to set properly. The elastic bands are mounted within a prong that provides a base surface to receive the elastic band and has a movable tab member to thereby provide an enclosed opening to receive and hold each band. After the bands are positioned the associated movable tab is bent over the elastic band to hold it in place and provide a rounded contour that matches the tissue of the gum. The prongs can be easily bent for attachment of ligature wires from any direction to support other facial bones which are to set.
