28 patients in an orthodontic practice who demonstrated both characteristic malocclusion forms with deficiency in the sagittal, transverse and vertical dimensions and orofacial dyskinesia of the inner and outer circles were divided according to clinical criteria into two therapy groups within the framework of a pilot study. One group was treated exclusively with myofunctional therapy, the other with myofunctlonal therapy and orthodontic appliances (for example activators). Specific examination and goal parameters were documented at the commencement and the conclusion of therapy.
