Abstract
Abstract Bone augmentation in a mammalian body by insertion of a mesh comprising one or more fibrillar wires having a hydroxyl apatite coating into a bone cavity or socket. The one or more fibrillar wires are arranged or assembled into a woolly structure, which may be infused or cultured with a bone morphogenic protein. The mesh is sealed in the cavity to permit new bone to form over time, resulting in an osteointegrated matrix of bone reinforced by the fibrillar wires of the mesh.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
99 words
A method for reinforcement of a dental implant device in a maxillary/mandibular bone comprising the steps of: (a) coating one or more fibrillar wires with a hydroxy appetite; (b) forming the one or more fibrillar wires into a mesh having a woolly structure; (c) inserting the mesh into a cavity of the maxillary/mandibular bone; (d) sealing the mesh in the cavity to permit a bone matrix to form in the cavity, the bone matrix being integrated with the mesh; (e) coring the bone matrix to create an opening; and (f) fixably securing the dental implant device within the opening.
Claim 2
Independent Claim
99 words
A method for reinforcement of a dental implant device in a maxillary/mandibular bone comprising the steps of: (a) coating one or more fibrillar wires with a hydroxy appetite; (b) forming the one or more fibrillar wires into a mesh having a woolly structure; (c) inserting the mesh into a cavity of the maxillary/mandibular bone; (d) sealing the mesh in the cavity to permit a bone matrix to form in the cavity, the bone matrix being integrated with the mesh; (e) coring the bone matrix to create an opening; and (f) fixably securing the dental implant device within the opening.
Claim 3
Dependent Claim
25 words
The method according to claim 1 further comprising the step, after step (c), of: adhering the woolly structure to the maxillary/mandibular bone with an adhesive.
Claim 4
Dependent Claim
13 words
The method according to claim 2 wherein the adhesive comprises a fibron glue.
Claim 5
Dependent Claim
23 words
The method according to claim 1 further comprising the step of: energizing the mesh so as to promote bone growth into the cavity.
Claim 6
Dependent Claim
30 words

Claim 7
Dependent Claim
28 words
The method according to claim 1 wherein the one or more fibrillar wires comprise a metal selected from the group consisting of titanium, tungsten, gold, and stainless steel.
Claim 8
Dependent Claim
17 words
The method according to claim 6 wherein the one or more fibrillar wires include an oxide layer.
Claim 9
Dependent Claim
26 words
The method according to claim 1 further comprising the step, following step (a), of: coating the one or more fibrillar wires with a bone morphogenic protein.
Claim 10
Dependent Claim
24 words
The method according to claim 1 wherein the one or more fibrillar wires have a thickness in the range of 100 to 300 microns.
