Abstract
Abstract An improved spring assembly is provided for use in orthodontia and which serves to carry out the principle of Begg''s Orthodontic Technique in the free tipping and pure uprighting of the canines and first or second premolars. The assembly of the invention includes a spring which is configured into a combined helical and Archimedes spiral, and which is used in conjunction with a slotted bracket mounted on the tooth, and the usual arch wire, with the arch wire being held in the slot of the bracket by one of the actuating arms of the spring.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
An orthodontic appliance in the form of a spring for tipping and uprighting teeth, and for use in conjunction with an arch wire and a bracket mounted on the tooth to be processed and which receives the arch wire in a slot therein, said appliance comprising: a spring having a first end extending into said slot in said bracket, and said spring further having a helical spiral portion adjacent said first end, and in which said spring has a second end looped around the end of said bracket to form an Archimedes spiral between said helical spiral portion and said second end, and in which said second end is configured to engage the arch wire to provide the desired spring tension by the spring, so as to impart a stress to the tooth so as to pivot the tooth about a point in the longitudinal axis of the tooth.
Claim 2
Dependent Claim
149 words
An orthodontic appliance in the form of a spring for tipping and uprighting teeth, and for use in conjunction with an arch wire and a bracket mounted on the tooth to be processed and which receives the arch wire in a slot therein, said appliance comprising: a spring having a first end extending into said slot in said bracket, and said spring further having a helical spiral portion adjacent said first end, and in which said spring has a second end looped around the end of said bracket to form an Archimedes spiral between said helical spiral portion and said second end, and in which said second end is configured to engage the arch wire to provide the desired spring tension by the spring, so as to impart a stress to the tooth so as to pivot the tooth about a point in the longitudinal axis of the tooth.
Claim 3
Dependent Claim
139 words
An orthodontic appliance in the form of a spring for tipping and uprighting teeth, and for use in conjunction with an arch wire and a bracket mounted on the tooth to be processed and which receives the arch wire in a slot therein, said appliance comprising: a spring having a first end for extending into said slot in said bracket, and said spring further having a helical spiral portion adjacent said first end, in which said spring has a second end for extending into the slot in a bracket in an adjacent tooth, and said spring further has a helical spiral portion adjacent said second end, and in which said spring has a looped portion intermediate the aforesaid helical spring portions and two relatively straight portions respectively extending between the intermediate looped portion and the aforesaid helical spiral portions.
Claim 4
Dependent Claim
139 words
An orthodontic appliance in the form of a spring for tipping and uprighting teeth, and for use in conjunction with an arch wire and a bracket mounted on the tooth to be processed and which receives the arch wire in a slot therein, said appliance comprising: a spring having a first end for extending into said slot in said bracket, and said spring further having a helical spiral portion adjacent said first end, in which said spring has a second end for extending into the slot in a bracket in an adjacent tooth, and said spring further has a helical spiral portion adjacent said second end, and in which said spring has a looped portion intermediate the aforesaid helical spring portions and two relatively straight portions respectively extending between the intermediate looped portion and the aforesaid helical spiral portions.
Claim 5
Dependent Claim
18 words
The orthodontic appliance defined in claim 2, in which the intermediate looped portion has a helical spring configuration.
