Abstract

Abstract The invention contemplates a unitary intra-oral positioning fixture for use in orthodontic and/or periodontal therapy and bone augmentation. The fixture provides compliant support for two coacting sources of magnetic flux, respectively positioned on the lingual and buccal sides of a region of a tooth or teeth (and adjacent alveolar bone) requiring osteogenesis and soft-tissue repair.

Claims Analysis

Total Claims: 26
Claim 1
Independent Claim 108 words
As an article of manufacture, a unitary intra-oral positioning fixture for use in orthodontic and/or periodontal therapy and bone augmentation, said fixture comprising upstanding buccal and lingual flange members of magnetically transparent material adapted respectively for confronting conformance with the buccal and lingual sides of teeth and in overlap with an associated alveolar-bone region requiring osteogenesis and soft-tissue repair, means compliantly interconnecting said flange members in a manner to permit their selectively removable fixation to span said region, and means including separate polarized sources of magnetic flux carried by said buccal and lingual flange members in mutually facing relation and magnetically coacting with each other via said region.
Claim 2
Dependent Claim 108 words
As an article of manufacture, a unitary intra-oral positioning fixture for use in orthodontic and/or periodontal therapy and bone augmentation, said fixture comprising upstanding buccal and lingual flange members of magnetically transparent material adapted respectively for confronting conformance with the buccal and lingual sides of teeth and in overlap with an associated alveolar-bone region requiring osteogenesis and soft-tissue repair, means compliantly interconnecting said flange members in a manner to permit their selectively removable fixation to span said region, and means including separate polarized sources of magnetic flux carried by said buccal and lingual flange members in mutually facing relation and magnetically coacting with each other via said region.
Claim 3
Dependent Claim 32 words
The article of claim 1, in which said flange members establish therebetween a channel which is continuous for substantially the full extent of the maxillary or mandibular arch of a human being.
Claim 4
Dependent Claim 47 words
The article of claim 1, in which said lingual flange member extends continuously for substantially the full extent of the maxillary or manidublar arch of a human being, and in which said buccal flange comprises separably connectable arcuate portions having separate compliant connection to said lingual flange.
Claim 5
Dependent Claim 23 words
The article of claim 3, in which said buccal flange member extends continuously for substantially said full extent when said portions are interconnected.
Claim 6
Dependent Claim 28 words
The article of claim 1, in which opposed adjacent surfaces of said flange members are in contoured conformance with confronting adjacent buccal and lingual profiles of said region.
Claim 7
Dependent Claim 15 words
The article of claim 1, in which said material is a compliantly yieldable bio-compatible material.
Claim 8
Dependent Claim 25 words
The article of claim 1, in which said material is bio-compatible and is selected from the group which includes acrylic, epoxy, urethane and latex materials.
Claim 9
Dependent Claim 25 words
The article of claim 1, in which each of said sources is a permanent magnet oriented to establish a magnetically polarized region through said region.
Claim 10
Dependent Claim 15 words
The article of claim 8, in which said magnets are oriented in mutually flux-aiding relation.
Claim 11
Dependent Claim 15 words
The article of claim 8, in which said magnets are oriented in mutually flux-opposing relation.
Claim 12
Dependent Claim 31 words
The article of claim 1, in which the lingually mounted one of said magnets is mounted for displacement in a direction generally transverse to the direction of coaction through said region.
Claim 13
Dependent Claim 42 words
The article of claim 11, in which the lingually mounted magnet is movable in a vertical guide having fixed relation to the lingual flange member, and tongue-engageable means on said lingually mounted magnet for movably actuating the same in its vertical guide.
Claim 14
Dependent Claim 44 words
The article of claim 11, in which the lingually mounted magnet is fixed to an arch bar which courses the lingual side of the lingual flange and which is pivotally connected at its ends to the respective distal ends of the lingual flange member.
Claim 15
Dependent Claim 26 words
The article of claim 1, in which the means compliantly interconnecting said flange members is a labial flange integrally formed with said buccal and lingual flanges.
Claim 16
Dependent Claim 21 words
The article of claim 8, in which each of said magnets is relatively thin in the direction of its polarization axis.
Claim 17
Dependent Claim 16 words
The article of claim 15, in which each of said magnets is a generally circular disc.
Claim 18
Dependent Claim 15 words
The article of claim 15, in which each of said magnets is generally rectangularly prismatic.
Claim 19
Dependent Claim 91 words
As an article of manufacture, a unitary intraoral positioning fixture for use in orthodontic and/or periodontal therapy and bone augmentation, said fixture comprising a lingual base of magnetically transparent material with a polarized source of magnetic flux mounted thereto in adjacency to the lingual side of a region of alveolar bone requiring osteogenesis, bone-remodeling and soft-tissue repair, and a second source of magnetic flux carried by said base and mounted for adjacency to the buccal side of said region and oriented for magnetic coaction with said first source via said region.
Claim 20
Dependent Claim 91 words
As an article of manufacture, a unitary intraoral positioning fixture for use in orthodontic and/or periodontal therapy and bone augmentation, said fixture comprising a lingual base of magnetically transparent material with a polarized source of magnetic flux mounted thereto in adjacency to the lingual side of a region of alveolar bone requiring osteogenesis, bone-remodeling and soft-tissue repair, and a second source of magnetic flux carried by said base and mounted for adjacency to the buccal side of said region and oriented for magnetic coaction with said first source via said region.
Claim 21
Dependent Claim 45 words
The article of claim 18, in which said base is the lingual flange of a fixture which integrally further includes labial and buccal flanges to define a channel adapted to span opposed areas of alveolar bone, said second source being mounted to said buccal flange.
Claim 22
Dependent Claim 23 words
The article of claim 18, in which said base is a dental plate and said second source is mounted thereto via interdental wire.
Claim 23
Dependent Claim 14 words
The article of claim 20, in which said dental plate is an orthodontic appliance.
Claim 24
Dependent Claim 117 words
As an article of manufacture, a unitary intraoval positioning fixture for use in orthodontic and/or periodontal therapy and bone augmentation, said fixture comprising upstanding buccal and lingual and flange members of magnetically transparent material adapted respectively for confronting conformance with the buccal and lingual sides of teeth and in overlap with an associated alveolar-bone region requiring osteogenesis, bone-remodeling in general and soft-tissue repair, means compliantly interconnecting said flange members in a manner to permit their selectively removable fixation to span said region, and means including separate elements of magnetic-flux-conducting material carried by said buccal and lingual flange members, one of said elements being permanently polarized and magnetically coacting with the other of said elements via said region.
