Abstract
Abstract An orthodontic pliers especially useful for bending the alignment wire end during all phases of the Begg orthodontic technique. The pliers comprise a pair of pivoted jaw members from the ends of which integrally extend a male and female beak which are preferably formed at substantially right angles to their respective jaws. In a preferred embodiment, the male beak comprises a substantially cylindrical member that mates with the female beak which is comprised of a semi-tubular upstanding member having an inner arcuate surface to cooperate with the male member. The pliers enable quick and easy bending of the arch wire ends without deforming the main arch wire.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
149 words
An orthodontic pliers, which comprises: first and second jaw members pivotally coupled to each other and having handle means extending laterally from one end thereof and wire bending means extending transversely from the other end thereof; said wire bending means including a first elongated bending member having an arcuate outer surface and connected to said other end of said first jaw member at a first junction point, and a second elongated bending member connected to said other end of said second jaw member at a second junction point and comprising a semi-tubular body having an arcuate inner surface complementary to and adapted to mate with said arcuate outer surface of said first elongated bending member; the major portion of said first and second elongated bending members extending substantially beyond their respective junction points with said first and second jaw members for permitting intra-oral bending of orthodontic arch wires therebetween.
Claim 2
Dependent Claim
149 words
An orthodontic pliers, which comprises: first and second jaw members pivotally coupled to each other and having handle means extending laterally from one end thereof and wire bending means extending transversely from the other end thereof; said wire bending means including a first elongated bending member having an arcuate outer surface and connected to said other end of said first jaw member at a first junction point, and a second elongated bending member connected to said other end of said second jaw member at a second junction point and comprising a semi-tubular body having an arcuate inner surface complementary to and adapted to mate with said arcuate outer surface of said first elongated bending member; the major portion of said first and second elongated bending members extending substantially beyond their respective junction points with said first and second jaw members for permitting intra-oral bending of orthodontic arch wires therebetween.
Claim 3
Dependent Claim
28 words
The orthodontic pliers as set forth in claim 1, wherein said first and second elongated bending members extend only unidirectionally from said first and second junction points, respectively.
Claim 4
Dependent Claim
27 words
The orthodontic pliers as set forth in claim 1, wherein said first and second elongated bending members extend bi-directionally from said first and second junction points, respectively.
Claim 5
Dependent Claim
41 words
The orthodontic pliers as set forth in claim 1, wherein said wire bending means are comprised of mating surfaces which cooperate to bend a wire placed therebetween in a plane substantially parallel to the plane of movement of said jaw members.
Claim 6
Dependent Claim
23 words
The orthodontic pliers as set forth in claim 1, wherein said arcuate surfaces of said first and second bending members are substantially cylindrical.
Claim 7
Dependent Claim
23 words
The orthodontic pliers as set forth in claim 1, wherein said arcuate surfaces of said first and second bending members are substantially conical.
