Integrated oral magnetic osteogenic and orthodontic appliances

Claim 2

An oral osteogenic and orthodontic appliance in which at least two magnets are adapted to be mounted by archwires to the upper and lower jaws so that magnetic fields will be displaced relative to each other to promote osteogenesis and soft-tissue repair, said appliance including at least two dental modules, each module comprising a permanent bar magnet retained within a peripherally continuous shield of electrically conductive material so as to expose the magnet only at its poles, whereby flux concentration on the magnet axis is enhanced at the poles of each magnet, tooth-connected maxillary and mandibular archwires for supporting the dental modules, one module-supporting archwire supporting a first module on a vertically oriented axis and the other module-supporting archwire supporting the other module on a vertically oriented axis, the lower pole of the upper module magnet and the upper pole of the lower module magnet being in substantially opposed and closely spaced but axially offset adjacency for the jaw-closed condition; whereby, reaction between said magnets develops a tooth-displacement force effective to displace at least one tooth in one of the jaws and to thereby develop a void in the one jaw in the wake of such tooth displacement, and further whereby, in the course of jaw articulation, the magnetic fields of said magnets react to produce in the developing-void region an external field which varies as a function of jaw articulation, said external field being therapeutically beneficial as an aid to formation of new bone in the void region.

Claim 3

The appliance of claim 1, in which said adjacent poles are in partial overlap and are of like polarity.

Claim 4

The appliance of claim 1, in which said poles are in partial overlap and are of opposite polarity.

Claim 5

An oral osteogenic and orthodontic appliance in which at least two magnets are adapted to be mounted to the upper and lower jaws so that magnetic fields will be displaced relative to each other to promote osteogenesis and soft-tissue repair, said appliance including at least two dental modules, each module comprising a permanent disc magnet with its faces oppositely polarized and retained within a peripherally continuous shield of electrically conductive material so as to expose the magnet only at polarized faces, whereby flux concentration on the magnet axis is enhanced at the polarized faces of each magnet, first tooth-connected means of the upper jaw supporting a first module on an axis oriented horizontally between the cheek side and the tongue side of the region of the connected tooth, and second tooth-connected means of the upper jaw supporting a second module on an axis oriented horizontally between the cheek side and the tongue side of the region of the connected lower-jaw tooth, the modules having adjacent polarized faces in closely spaced but axially offset adjacency for the jaw-closed condition, the orientation of said offset being generally horizontal and placing the axis of one of said modules in anterior relation to the other of said modules for the jaw-closed condition; whereby reaction between said magnets develops a tooth-displacement force effective to displace at least one tooth in one of the jaws and to thereby develop a void in the one jaw in the wake of such tooth displacement, and further whereby, in the course of jaw articulation, the magnetic fields of said magnets react to produce in the developing-void region an external field which varies as a function of jaw articulation, said external field being therapeutically beneficial as an aid to formation of new bone in the void region.

Claim 6

An oral osteogenic and orthodontic appliance in which at least two magnets are adapted to be mounted to the upper and lower jaws so that magnetic fields will be displaced relative to each other to promote osteogenesis and soft-tissue repair, said appliance including at least two dental modules, each module comprising a permanent disc magnet with its faces oppositely polarized and retained within a peripherally continuous shield of electrically conductive material so as to expose the magnet only at polarized faces, whereby flux concentration on the magnet axis is enhanced at the polarized faces of each magnet, first tooth-connected means of the upper jaw supporting a first module on an axis oriented horizontally between the cheek side and the tongue side of the region of the connected tooth, and second tooth-connected means of the upper jaw supporting a second module on an axis oriented horizontally between the cheek side and the tongue side of the region of the connected lower-jaw tooth, the modules having adjacent polarized faces in closely spaced but axially offset adjacency for the jaw-closed condition, the orientation of said offset being generally horizontal and placing the axis of one of said modules in anterior relation to the other of said modules for the jaw-closed condition; whereby reaction between said magnets develops a tooth-displacement force effective to displace at least one tooth in one of the jaws and to thereby develop a void in the one jaw in the wake of such tooth displacement, and further whereby, in the course of jaw articulation, the magnetic fields of said magnets react to produce in the developing-void region an external field which varies as a function of jaw articulation, said external field being therapeutically beneficial as an aid to formation of new bone in the void region.

Claim 7

The appliance of claim 4, in which the adjacent polarized faces are in substantial but less than total overlap and are of like polarity.

Claim 8

The appliance of claim 4, in which the adjacent polarized faces are in substantial but less than total overlap and are of opposite polarity.
