Abstract
Abstract An orthodontic bracket assembly including brackets mounted upon teeth to ect orthodontic treatment thereof is provided with a self adhesive layer adhered on one side thereof to the surface of the orthodontic bracket which is used to fasten the bracket upon a tooth. A protective foil is arranged to extend on one side of bracket wings formed upon the orthodontic bracket and defining a slot adapted to receive therein a regulating arch when the brackets are mounted upon teeth to be treated. The protective foil defines a gap or spacing within which the base of the orthodontic bracket extends and within which liquid adhesive may be introduced for attaching the bracket to the teeth to be treated.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
186 words
An orthodontic assembly including an orthodontic bracket which is particularly adapted for use by being first mounted with a transfer matrix upon a positive model of a tooth which is to have said bracket ultimately applied thereto after removal of said bracket from said positive model, said assembly comprising a bracket base defining on said orthodontic bracket a surface for fastening said bracket upon a tooth, bracket wings extending laterally from said base of said bracket and defining therebetween a slot adapted to receive therein a regulating arch, a self-adhesive strip removably adhered on one side thereof to said fastening surface of said bracket base and adapted to have its opposite side removably adhered to a model tooth, and a protective foil extending between said bracket wings and said bracket base and also extending to said adhesive strip in surrounding relationship with said bracket base, said protective foil being arranged to prevent penetration of the material forming said transfer matrix to the space between said bracket base and said bracket wings when said bracket is being mounted upon said positive tooth model with said transfer matrix.
Claim 2
Dependent Claim
186 words
An orthodontic assembly including an orthodontic bracket which is particularly adapted for use by being first mounted with a transfer matrix upon a positive model of a tooth which is to have said bracket ultimately applied thereto after removal of said bracket from said positive model, said assembly comprising a bracket base defining on said orthodontic bracket a surface for fastening said bracket upon a tooth, bracket wings extending laterally from said base of said bracket and defining therebetween a slot adapted to receive therein a regulating arch, a self-adhesive strip removably adhered on one side thereof to said fastening surface of said bracket base and adapted to have its opposite side removably adhered to a model tooth, and a protective foil extending between said bracket wings and said bracket base and also extending to said adhesive strip in surrounding relationship with said bracket base, said protective foil being arranged to prevent penetration of the material forming said transfer matrix to the space between said bracket base and said bracket wings when said bracket is being mounted upon said positive tooth model with said transfer matrix.
Claim 3
Dependent Claim
48 words
An assembly according to claim 1 wherein said self-adhesive strip consists of a double adhesive layer having adhesive on both sides thereof and wherein said opposite side of said strip which is adapted to be removably adhered to a model tooth includes a removable cover strip extending thereover.
Claim 4
Dependent Claim
59 words
An assembly according to claim 1 wherein said bracket is made of metal with said bracket base having perforations extending therethrough, said protective foil being arranged with one side thereof facing said bracket base, said one side of said protective foil including projections extending therefrom toward said base to provide a spacing between said base and said protective foil.
Claim 5
Dependent Claim
51 words
An assembly according to claim 1 wherein said bracket is made of plastic material and wherein said protective foil extends on one side thereof in smooth abutment with said bracket base, said protective foil being configured to provide a spacing between the lateral edges of said base and said protective foil.

74 words
An assembly according to claim 1 further comprising a model tooth having said opposite side of said self-adhesive strip adhered thereto, and a transfer matrix adapted to enable said assembly to be transferred from said model tooth to a tooth to be orthodontically treated thereby, said transfer matrix being composed of plastic material having a modulus of elasticity of about 3000 Kg/cm 2 and a wall thickness of between about 0.5 to 1.0 mm.
Claim 10
Dependent Claim
48 words
An assembly according to claim 8 including a positive jaw model having said model tooth formed as part thereof and including gum portions from which said model tooth extends, said transfer matrix being formed on said model tooth so as to avoid contact thereof with said gum portions.
Claim 11
Dependent Claim
46 words
An assembly according to claim 9 wherein said transfer matrix includes a front side along an edge thereof facing said gums and two lateral edges close to said bracket base, said transfer matrix being cut out on said front side and along said two lateral edges
Claim 12
Dependent Claim
28 words
An assembly according to claim 10 wherein said transfer matrix is subdivided prior to being utilized upon teeth to be orthodontically treated according to groups of individual teeth.
