Abstract
Abstract A method and composition for promoting the growth of bone that are particularly useful in treating bone defects in the human jaw. The method includes surgically exposing the bony defect, cleaning the defect and adjacent teeth, and implanting the composition in the bony defect. The bone growing composition includes two sizes of Hydroxyapatite for supporting the growth of new bone, Tetracycline for its antibiotic effect, freeze dried decalcified human bone for promoting bone growth, and Fibronectin for promoting connective tissue generation and for jelling the bone growing composition.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
107 words
A method of promoting the growth of bone in a living creature comprising the steps of: a. providing a first size of hydroxyappetite; b. providing a second size of hydroxyappetite; c. providing fibronectin; d. providing a source of collagen; e. mixing said first size hydroxyappetite, said second size hydroxyappetite, said source of collagen and said fibronectin to form a graft composition; f. surgically operating on the living creature to expose living bone; g. inserting said graft composition adjacent said living bone to treat said living bone after said living bone has been surgically exposed; and h. surgically covering said living bone and said adjacently located graft composition.
Claim 2
Independent Claim
107 words
A method of promoting the growth of bone in a living creature comprising the steps of: a. providing a first size of hydroxyappetite; b. providing a second size of hydroxyappetite; c. providing fibronectin; d. providing a source of collagen; e. mixing said first size hydroxyappetite, said second size hydroxyappetite, said source of collagen and said fibronectin to form a graft composition; f. surgically operating on the living creature to expose living bone; g. inserting said graft composition adjacent said living bone to treat said living bone after said living bone has been surgically exposed; and h. surgically covering said living bone and said adjacently located graft composition.
Claim 3
Dependent Claim
41 words
The method of promoting growth of bone of claim 1, wherein said living creature has a mouth and said step of surgically operating on the living creature to expose living bone comprises surgically operating on the mouth of said living creature.
Claim 4
Dependent Claim
50 words
The method of promoting growth of bone of claim 2 wherein the mouth of said living creature has at least one tooth having a root and said step of surgically operating on the living creature to expose living bone also comprises surgically operating to expose the root of said tooth.
Claim 5
Dependent Claim
44 words
The method of promoting growth of bone of claim 3 further comprising the step of preparing the surface of the root of said tooth by using an abrasive after the step of surgically operating to expose living bone and the root of said tooth.
Claim 6
Dependent Claim
43 words
The method of promoting growth of bone of claim 4 further comprising the step of applying a solution to the root of said tooth to remove any smear layer after the step of preparing the root of said tooth by using an abrasive.
Claim 7
Dependent Claim
45 words
The method of promoting growth of bone of claim 5 wherein said step of inserting said graft composition adjacent said living bone also comprises covering the surface of the root of said tooth with said graft composition to provide for reattaching bone to the tooth.
Claim 8
Dependent Claim
48 words
The method of promoting growth of bone of claim 6 further comprising the steps of providing a syringe, inserting said graft composition in said syringe after said graft composition is formed, and wherein said step of inserting said graft composition is accomplished through the use of said syringe.
Claim 9
Dependent Claim
37 words
The method of promoting growth of bone of claim 6 wherein said step of inserting said graft composition comprises inserting additional graft composition to bring the level of graft composition beyond that of the adjacent living bone.
Claim 10
Dependent Claim
32 words
The method of promoting growth of bone of claim 8 further comprising the step of administering a nutrient after said step of covering said living bone and said adjacently located graft composition.
Claim 11
Dependent Claim
23 words
The method of promoting growth of bone of claim 9 wherein said step of administering a nutrient comprises administering at least one vitamin.
Claim 12
Dependent Claim
23 words
The method of promoting growth of bone of claim 9 wherein said step of administering a nutrient comprises administering at least one mineral.
Claim 13
Dependent Claim
31 words
The method of promoting growth of bone of claim 1 further comprising repeating the steps a. through h. in claim 17 to promote further growth of bone adjacent previously grown bone.
