Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 86 words
An orthodontic device for applying elastic forces within a person''s mouth in performing orthodontic treatment, said device comprising a molded ring-sHaped body of elastomeric material having a uniform cross section throughout, said cross section defined by radially arranged inner and outer sides, the inner side being symmetrically V-shaped with the base of the V-shaped side being innermost, and a thin web across the V-shaped side closing the center of the body, said web having an axial thickness substantially less than the axial thickness of the body.
Claim 2
Dependent Claim 86 words
An orthodontic device for applying elastic forces within a person''s mouth in performing orthodontic treatment, said device comprising a molded ring-sHaped body of elastomeric material having a uniform cross section throughout, said cross section defined by radially arranged inner and outer sides, the inner side being symmetrically V-shaped with the base of the V-shaped side being innermost, and a thin web across the V-shaped side closing the center of the body, said web having an axial thickness substantially less than the axial thickness of the body.
Claim 3
Dependent Claim 34 words
The device of claim 1, and a diametrically extending slit in said web of a width less than that of the archwire to thereby frictionally hold the device on the archwire before final placement.
Claim 4
Dependent Claim 104 words
An orthodontic device for use with orthodontic apparatus in a person''s mouth to apply elastic tooth moving forces between a plurality of points, said device comprising a plurality of molded annular bodies of elastomeric material connected together in coplanar chain form relationship so the outer circumferences of connected bodies overlap, each body having a uniform cross section throughout, said cross section being defined by radially inward and outward facing sides, and the radially inward facing side including a pair of annular faces converging radially inwardly to a line edge, wherein the device when connected between two points in the mouth exerts tooth moving forces.
Claim 5
Dependent Claim 104 words
An orthodontic device for use with orthodontic apparatus in a person''s mouth to apply elastic tooth moving forces between a plurality of points, said device comprising a plurality of molded annular bodies of elastomeric material connected together in coplanar chain form relationship so the outer circumferences of connected bodies overlap, each body having a uniform cross section throughout, said cross section being defined by radially inward and outward facing sides, and the radially inward facing side including a pair of annular faces converging radially inwardly to a line edge, wherein the device when connected between two points in the mouth exerts tooth moving forces.
Claim 6
Dependent Claim 114 words
An orthodontic device for use with orthodontic apparatus in a person''s mouth to apply elastic tooth moving forces between a plurality of points, said device comprising a plurality of molded ring-shaped bodies of elastomeric material connected together in coplanar relationship so the outer circumferences of connected bodies overlap and the centers thereof are aligned along a straight line, each body having a uniform cross section throughout except at the connection with another body, said cross section defined by radially arranged inner and outer sides, and the inner side being V-shaped with the base of the V-shaped side being innermost, wherein the device when connected between two points in the mouth exerts tooth moving forces.
Claim 7
Dependent Claim 114 words
An orthodontic device for use with orthodontic apparatus in a person''s mouth to apply elastic tooth moving forces between a plurality of points, said device comprising a plurality of molded ring-shaped bodies of elastomeric material connected together in coplanar relationship so the outer circumferences of connected bodies overlap and the centers thereof are aligned along a straight line, each body having a uniform cross section throughout except at the connection with another body, said cross section defined by radially arranged inner and outer sides, and the inner side being V-shaped with the base of the V-shaped side being innermost, wherein the device when connected between two points in the mouth exerts tooth moving forces.
Claim 8
Dependent Claim 21 words
The device of claim 2, wherein the outer side is flat and extends perpendicular to the radial plane of the body.
Claim 9
Dependent Claim 14 words
The device of claim 3, wherein radially extending end faces extend between the sides.
Claim 10
Dependent Claim 12 words
The device of claim 4, where the bodies define central openings therethrough.
