ABSTRACT:
An orthopedic appliance for correcting an abnormal, Class II malocclusion. In the latter the mandible and its teeth are posteriorly displaced resulting in improper biting and impaired physical appearance. An adjustable bar attached in each side of the mouth to upper and lower molars is used to join the upper and lower rows of teeth. The point of attachment to the lower row of teeth is somewhat forward of the corresponding point in the upper row so that the lower jaw is forced forward when the mouth is closed. In adolescents, and to some extent in adults, this produces permanent muscle changes of the lower jaw and its joint, bone remodeling and permanent correction of the occlusion to a normal Class I bite. The appliance uses no telescoping sections, is easily manufactured and is readily adjustable during installation and wearing.
