Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
136 words
In combination with an orthodontic bracket of the type adapted to receive an orthodontic arch wire, a metal base member adapted to be adhered to the surface of a tooth which comprises a base plate having one surface thereof attached to said orthodontic bracket, a U-shaped wall member extending substantially perpendicular to and from the other surface of said base plate to form the walls of a pocket, and a flange extending from the free end of each leg of said U-shaped wall member inwardly across the pocket formed by said U-shaped wall member so as to form a pocket enclosure having an open wall and open face opposite said base plate adapted to be filled with a bonding composition to facilitate adhesion of said metal base member and bracket to the surface of a tooth.
Claim 2
Dependent Claim
136 words
In combination with an orthodontic bracket of the type adapted to receive an orthodontic arch wire, a metal base member adapted to be adhered to the surface of a tooth which comprises a base plate having one surface thereof attached to said orthodontic bracket, a U-shaped wall member extending substantially perpendicular to and from the other surface of said base plate to form the walls of a pocket, and a flange extending from the free end of each leg of said U-shaped wall member inwardly across the pocket formed by said U-shaped wall member so as to form a pocket enclosure having an open wall and open face opposite said base plate adapted to be filled with a bonding composition to facilitate adhesion of said metal base member and bracket to the surface of a tooth.
Claim 3
Dependent Claim
27 words
The combination of claim 1 which further includes within said pocket enclosure a bonding composition which consists of cured polymethyl methacrylate and polycyclohexyl methacrylate in hexyl methacrylate.
Claim 4
Dependent Claim
113 words
An improved orthodontic bracket of the type adapted to receive an orthodontic arch wire which comrpises orthodontic bracket means adapted to receive an orthodontic arch wire on one surface thereof, a pair of U-shaped extensions extending substantially perpendicular to and from the other surface of said bracket means, said U-shaped extensions being oppositely disposed to one another with the open ends thereof in facing relation to one another to form the ends of a pocket enclosure adapted to be filled with a bonding composition to facilitate adhesion of said bracket to the surface of a tooth, and a flange attached to the free end of each leg of each of said U-shaped members.
Claim 5
Dependent Claim
