Abstract
An improved orthopedic appliance for correcting a Class II malocclusion comprising an acrylic anterior segment molded to fit the lower mouth and dentition and two acrylic posterior segments molded to fit the upper mouth and dentition of a patient and an expansion screw connecting each posterior segment to the anterior segment for expandible movement between the anterior segment and the posterior segments. A method of correcting a Class II Division 1 malocclusion using an expandable but otherwise conventional orthopedic appliance. The appliance is expanded in stages to maximize the utilization of corrective lower jaw movements which result from the anchoring of the orthopedic appliance in the patient's upper mouth.
