Abstract
Abstract A removable palatal arch wire is provided having a generally Ushaped, integral compressible loop portion formed intermediate its length adapted to function as a removable and adjustable spring whereby the force incorporated into said wire to reciprocally rotate, expand, contract, intrude, and/or torque the upper molars to which it is attached can be varied as desired merely by compressing or expanding said loop portion, depending upon the force required to shift said molars in order to provide sufficient space for the alignment of the adjacent anterior teeth by an orthodontist or dentist.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
An orthodontic appliance for applying rotating, expanding, contracting, intruding, and/or torquing forces to a pair of opposed molars in the upper arch of a person comprising, brackets mounted on the lingual sides of the molars, each bracket having a rectangular in cross-section generally mesiodistally extending opening, a round wire of spring steel of a length substantially equal to the palatal distance between the brackets having an open U-shaped spring loop intermediate the terminal ends thereof, and said tErminal ends being bent over double to form rectangularly shaped inserts to removably and frictionally fit in the bracket openings and preclude relative rotation therebetween, wherein the wire is arched in substantial conformity to the palate and the loop extends substantially concentric to the palate.
Claim 2
Dependent Claim
122 words
An orthodontic appliance for applying rotating, expanding, contracting, intruding, and/or torquing forces to a pair of opposed molars in the upper arch of a person comprising, brackets mounted on the lingual sides of the molars, each bracket having a rectangular in cross-section generally mesiodistally extending opening, a round wire of spring steel of a length substantially equal to the palatal distance between the brackets having an open U-shaped spring loop intermediate the terminal ends thereof, and said tErminal ends being bent over double to form rectangularly shaped inserts to removably and frictionally fit in the bracket openings and preclude relative rotation therebetween, wherein the wire is arched in substantial conformity to the palate and the loop extends substantially concentric to the palate.
Claim 3
Dependent Claim
35 words
An orthodontic appliance as defined in claim 1, wherein said spring loop includes parallel opposed leg portions and an arcuate bight portion and bending of the bight portion controls the force output of the loop.
Claim 4
Dependent Claim
18 words
An orthodontic appliance as defined in claim 1, wherein the open end of said spring loop faces mesially.
Claim 5
Dependent Claim
120 words
An orthodontic appliance for applying rotating, expanding, contracting, intruding, and/or torquing forces to a pair of opposed molars in the upper arch of a person comprising means mounted on the lingual side of the molars, each said means having a non-circular in cross section generally mesiodistally extending opening, a round wire of spring steel of a length substantially equal to the palatal distance between the brackets having an open U-shaped spring loop intermediate the terminal ends thereof, non-circular inserts on said terminal ends shaped to removably and frictionally fit in the openings of said means and preclude relative rotation therebetween, wherein the wire is arched in substantial conformity to the palate and the loop extends substantially concentric to the palate.
Claim 6
Dependent Claim
120 words
An orthodontic appliance for applying rotating, expanding, contracting, intruding, and/or torquing forces to a pair of opposed molars in the upper arch of a person comprising means mounted on the lingual side of the molars, each said means having a non-circular in cross section generally mesiodistally extending opening, a round wire of spring steel of a length substantially equal to the palatal distance between the brackets having an open U-shaped spring loop intermediate the terminal ends thereof, non-circular inserts on said terminal ends shaped to removably and frictionally fit in the openings of said means and preclude relative rotation therebetween, wherein the wire is arched in substantial conformity to the palate and the loop extends substantially concentric to the palate.
