Abstract
The invention contemplates an orthodontic palatal expansion device wherein separate palate-body halves are attachable to adjacent maxillary teeth and incorporate permanent magnets arranged in a repulsion mode and mounted in such a way as to apply force needed to split the mid-palatal suture. The reacting fields of these magnets also aid in reorganization of the tissues to insure maintenance of the expansion and to accelerate osteogenesis. The device may be constructed for fixation to the patient, as via orthodontic bands, or it may be fashioned with orthodontic wires that permit selective removal and replacement by the patient.
