Abstract
Abstract An orthodontic bracket is provided which comprises a pair of spaced apart arch wire securement members, each having an opening with a flared mouth. The members are secured at opposite ends of a base which base is securable to the anterior surface of a tooth. An auxiliary bracket is secured to the base between the members which bracket includes a slot that extends in a straight line which traverses the openings of the members. The auxiliary bracket includes a vertically extending channel for receipt of an insert bracket which has an enlarged head which is in the shape of said spaced apart members. Said spaced apart members and said enlarged head include an opening with a flared mouth to enable self-locking of an arch wire in the openings of said members.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
146 words
In combination an orthodontic bracket for securement to the anterior surface of teeth and an arch wire, said bracket including a pair of planar C-shaped spaced securement members, each of said members including a portion of reduced thickness each of said members including an opening with a flared mouth to facilitate insertion of said arch wire, said mouth being narrowest at the junction of said mouth and said opening, the diameter of said arch wire being slightly larger than the width of the smallest opening of said mouth so that said arch wires are snapped into said opening when said arch wire is urged therein, said members each being deformed in the plane of said member with said mouth closed by squeezing said members about said opening with a plier type tool so that said bracket securely holds said arch wire at two spaced apart points.
Claim 2
Dependent Claim

In combination an orthodontic bracket for securement to the anterior surface of teeth and an arch wire, said bracket including a pair of planar C-shaped spaced securement members, each of said members including a portion of reduced thickness each of said members including an opening with a flared mouth to facilitate insertion of said arch wire, said mouth being narrowest at the junction of said mouth and said opening, the diameter of said arch wire being slightly larger than the width of the smallest opening of said mouth so that said arch wires are snapped into said opening when said arch wire is urged therein, said members each being deformed in the plane of said member with said mouth closed by squeezing said members about said opening with a plier type tool so that said bracket securely holds said arch wire at two spaced apart points.
Claim 3
Dependent Claim
158 words
An orthodontic bracket for securement to the anterior surface of teeth, said bracket including a pair of spaced securement members, each of said members including an opening with a flared mouth to facilitate insertion of an arch wire, said mouth being narrowest at the junction of said mouth and said opening, the diameter of said arch wire being slightly larger than the width of the smallest opening of said mouth so that said arch wires snap into said opening when said arch wire is urged therein, said members each being deformable so that said mouth is closed by squeezing said member about said opening with a plier type tool to securely receive said arch wire at two spaced apart points and means for securing an insert bracket having a securement head, said head being disposed closer to the roots of said teeth to enable an arch wire to be secured to said teeth at one point per tooth.
Claim 4
Dependent Claim
158 words
An orthodontic bracket for securement to the anterior surface of teeth, said bracket including a pair of spaced securement members, each of said members including an opening with a flared mouth to facilitate insertion of an arch wire, said mouth being narrowest at the junction of said mouth and said opening, the diameter of said arch wire being slightly larger than the width of the smallest opening of said mouth so that said arch wires snap into said opening when said arch wire is urged therein, said members each being deformable so that said mouth is closed by squeezing said member about said opening with a plier type tool to securely receive said arch wire at two spaced apart points and means for securing an insert bracket having a securement head, said head being disposed closer to the roots of said teeth to enable an arch wire to be secured to said teeth at one point per tooth.
Claim 5
Dependent Claim
21 words
The bracket of claim 1 wherein slotted means are in a line with said securement members to receive said arch wire.
Claim 6
Dependent Claim
35 words
The bracket of claim 3 wherein said slotted means includes a slot having a cross-section which is the same shape as said arch wire so that said arch wire is held snuggly in said slot.

The bracket of claim 1 and further including an auxiliary bracket having a slot which extends in the direction of and is aligned with the openings in said members.
Claim 8
Dependent Claim
92 words
An orthodontic bracket comprising a pair of spaced apart planar C-shaped arch wire securement members each having a portion of reduced thickness and an opening with a flared mouth and configured to enable snapping said arch wire into said opening, an intermediate member having a slot that extends in a direction which is aligned with the opening of said members, said intermediate member having a vertically extending channel for receipt of a bracket having an enlarged head which includes an opening with a flared mouth for securement of an arch wire therein.
Claim 9
Dependent Claim
92 words
An orthodontic bracket comprising a pair of spaced apart planar C-shaped arch wire securement members each having a portion of reduced thickness and an opening with a flared mouth and configured to enable snapping said arch wire into said opening, an intermediate member having a slot that extends in a direction which is aligned with the opening of said members, said intermediate member having a vertically extending channel for receipt of a bracket having an enlarged head which includes an opening with a flared mouth for securement of an arch wire therein.
Claim 10
Dependent Claim
22 words
The bracket of claim 6 wherein said intermediate member includes a pair of flanges which extend in opposed directions from said slot.
