Abstract: Both fixed and removable functional appliances are disclosed employing magnets to provide the requisite force for accomplishing Class II malocclusion correction. Magnets are employed buccally and/or lingually, either operating in sliding or shearing mode or with the inter-pole gap inclined mesio-distally to develop an effective horizontal force component. Long thin rectangular magnets are incorporated bilaterally and inclined mesio-distally in the tooth capping sections of functional type base structures overlying the occlusal surface. Curved or angled straight magnets are located in anterior flanges of functional type base structures for developing horizontal thrust on the mandible. A number of closed magnetic circuits using either low reluctance keepers or shaped magnets are described for providing either increased force or travel or both.

Abstract: A kit is provided containing magnetic modules, attachment wire and a set of gages. The modules are rectangular prismatic formed from a cobalt-samarium alloy, covered with a chlorinated poly-p-xylene coating or stainless steel and jacketed in stainless steel with orthogonally related passages on opposite sides having rectangular cross-sections for receiving with a snug fit the rectangular cross-section attachment wire formed by welding together two lengths of standard edgewise wire. The gages provide means for spacing the modules when the latter are incorporated in an appliance.Appliances are illustrated for accomplishing a variety of orthodontic procedures. The construction of the modules and attachment wire permits construction of appliances where the modules are constrained in the jaw closed in centric condition to translate parallel to their respective pole faces in a "sliding" fashion.

Abstract: 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.

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.

Abstract: The invention contemplates a specific coil configuration adapted for application to particular regions of the body, for use in treating a selected such region with pulsed electromagnetic signals which are induced within the body as electric voltage and concomitant current signals which alter the growth, repair and maintenance behavior of living tissues and cells within the body region under treatment.

Abstract: The invention contemplates a boot removably adapted for attachment to an engine hoof and carrying at least one multi-turn electrical coil which effectively surrounds at least the bottom of the hoof. A pulse generator and power source are self-contained in a housing carried at the back side of the boot, with provision for electrically exciting the coil with a succession of therapeutically beneficial low-voltage unidirectional asymmetrical pulses.
