Fifteen adult patients with skeletal mandibular prognathism or openbite underwent surgical and orthodontic treatment, then received myofunctional therapy. Cephalograms, facial photographs and oral models were taken on each patient. Patients were then videotaped, frontally and laterally. Observations were made of forty different oral behaviors and oral rest posture. Changes in morphology, speech, and swallowing are described and evaluated.
