Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
116 words
A preformed universal orthodontic arch made of a spring-type material comprising: a row of minor arches having apices that extend in the same general direction, each minor arch curving from the opposite sides of its apex in a direction away from said first mentioned direction to spaced minor arch ends, the adjacent minor arch ends of adjacent minor arches being common to each other and joining the adjacent minor arch ends to each other, said joined minor arch ends being spaced in accordance with the desired spacing of the teeth in the dental arch; and a mounting member secured to each of the joined minor arch ends that is adapted to be mounted on a tooth.
Claim 2
Dependent Claim
116 words
A preformed universal orthodontic arch made of a spring-type material comprising: a row of minor arches having apices that extend in the same general direction, each minor arch curving from the opposite sides of its apex in a direction away from said first mentioned direction to spaced minor arch ends, the adjacent minor arch ends of adjacent minor arches being common to each other and joining the adjacent minor arch ends to each other, said joined minor arch ends being spaced in accordance with the desired spacing of the teeth in the dental arch; and a mounting member secured to each of the joined minor arch ends that is adapted to be mounted on a tooth.
Claim 3
Dependent Claim
17 words

Claim 5
Dependent Claim
43 words
The orthodontic arch according to claim 1 wherein each of said minor arch ends has at least one looped portion whose apex faces in the general direction of the minor arch apices and thus in the general direction of its associated tooth apex.
Claim 6
Dependent Claim
52 words
The orthodontic arch according to claim 1 wherein each mounting member comprises an attachment in which a minor arch end is inserted; and wherein the arch ends at the outermost extremities of the row are each formed into a bend that extends about the attachment end that faces the minor arch apices.
Claim 7
Dependent Claim
33 words
The orthodontic arch according to claim 4 wherein each of said looped portions is located between two other looped portions in its minor arch end that faces away from the minor arch apices.

Claim 9
Dependent Claim
61 words
The orthodontic arch according to claim 4 wherein each of said looped portions is bent towards its associated mounting member, and thus towards its associated tooth anterior, and then is turned to lie on an axis that is parallel to the plane of the minor arches and that extends towards the minor arch apices and the apex of its associated tooth.
Claim 10
Dependent Claim
21 words
The orthodontic arch according to claim 6 said first mentioned looped portion and said other looped portions are of equal widths.
Claim 11
Dependent Claim
