ABSTRACT:
A single piece appliance for correcting oral abnormalities without wires or bands has a segment engaging anterior dentition of the maxillary arch and a pair of spaced segments extending downwardly and posteriorly from the anterior dentition engaging segment at a predetermined angle with respect to the anterior dentition engaging segment. Each downwardly extending segment includes a labial facing surface that forms an inclined plane at the predetermined angle with the anterior dentition engaging segment adapted to contact the lingual aspect of the incisal edges of selected teeth on the mandibular arch so that the lower jaw is urged forward and steeply upward while the upper jaw is urged backward when necessary. At least one longitudinal ridge extends across each labial facing surface at a prescribed location along the labial facing surface to restrict the forward and upward movement of the mandible when the incisal edges of selected teeth of the mandibular arch are in contact with the labial facing surface.
