A palatal body is custom configured and dimensioned to fit within the oral cavity with an outer edge conforming to and engaging the lingual faces of the teeth of the maxillary arch. The dimensions are chosen to retain the arch either in an expanded condition associated with separation of the mid-palatal suture, or in some other predetermined position following suitable prior treatment of a cleft palate patient. A plurality of diametrally or longitudinally polarized cylindrical magnets are arrayed in parallel and in parallel to the palate body, all oriented with their axes in the bucco-lingual direction, and individually mounted for rotation under the influence of intraoral activity for inducing therapeutic levels of voltage and current in the adjacent bone structure of the natural palate on either side of the palatal gap.
