ABSTRACT:
An appliance is disclosed for the correction of dental malpositions, and particularly for the distalization of molar teeth. A metal wire arch is fastened to the incisors and canines, and at least one small tube receives a portion of the wire arch which can move freely inside the tube. The tube has a fixed protrusion which is in contact with a coil-spring wound around the tube at one end. The coil-spring engages a sleeve fastened onto a metal band which is fitted to a malpositioned molar tooth. At the other end, the tube is provided with a hook-shaped projection. An inter-maxillary rubber band engages the hook and a similar hook-projection fastened to a molar of the antagonist jaw. The appliance is of the intra-oral and non-movable type, which is used to carry out a functional treatment which is similar to biological and natural rhythms. This device uses the muscular force that the patient exerts in order to tense the inter-maxillary elastic, when talking or chewing.
