Abstract

Provided herein are compositions and their methods of use to adhere (e.g., in wet and dry environments) a variety of materials together.

Claims (70)

1. An adhesive composition comprising:

(i) a multivalent metal salt selected from one of a tetracalcium phosphate or tricalcium phosphate;

(ii) an aqueous medium;

(iii) citric acid or malonic acid;

(iv) calcium citrate;

(v) phosphoserine;

wherein the adhesive strength of the adhesive composition upon curing is greater than 1,000 kPa.

2. The composition of claim 1 , wherein the aqueous medium is water.

3. The composition of claim 1 , wherein the phosphoserine is present in an amount from about 10% to about 90% weight by weight (w/w) of the total composition.

4. The composition of claim 1 , wherein the composition has a mean particle size of less than 1.000 mm.

5. The composition of claim 1 , wherein the composition has a tacky state for up to 12 minutes after mixing with the aqueous medium.

6. The composition of claim 5 , wherein the composition during the tacky state has a tack stress of between about 10 kPa and about 250 kPa after mixing with the aqueous medium.

7. The composition of claim 1 , wherein the composition has a putty state for up to 15 minutes after mixing with the aqueous medium.

8. The composition of claim 7 , wherein the composition during the putty state has a tack stress of between about 10 kPa and about 250 kPa after mixing with the aqueous medium.

9. The composition of claim 1 , further comprising an additive.

10. The composition of claim 9 , wherein the additive comprises a salt, a filler, a viscosity modifier, an antibiotic, or a medication.

11. A kit comprising an adhesive composition comprising:

(i) a multivalent metal salt selected from one of tetracalcium phosphate or tricalcium phosphate;

(ii) an aqueous medium;

(iii) citric acid or malonic acid;

(iv) calcium citrate;

(v) phosphoserine;

wherein the adhesive strength of the adhesive composition upon curing is greater than 1,000 kPa.

12. The kit of claim 11 , comprising a device for application of the adhesive composition.

13. The kit of claim 11 , comprising a device for preparation of the adhesive composition.

14. A method of filling a bone void resulting from the removal of a bone cyst, granuloma, abscess, or similar bone defect, wherein bone void is crestal, central, or lateral to the alveolar ridge or another portion of the facial skeleton, the method comprising:

a) preparing an adhesive composition comprising:

(i) a multivalent metal salt selected from one of tetracalcium phosphate or tricalcium phosphate;

(ii) an aqueous medium;

(iii) citric acid or malonic acid;

(iv) calcium citrate;

(v) phosphoserine;

wherein the adhesive strength of the adhesive composition upon curing is greater than 1,000 kPa;

and

b) placing the composition into said bone void;

wherein the composition hardens and/or cures in less than about 30 minutes.

15. The method of claim 14 , wherein the composition is allowed to remain undisturbed until resorption of the composition by the bone occurs.

16. A method of filling a bone void resulting from a prepared extraction site, the method comprising:

a) preparing an adhesive composition comprising:

(i) a multivalent metal salt selected from one of tetracalcium phosphate or tricalcium phosphate;

(ii) an aqueous medium;

(iii) citric acid or malonic acid;

(iv) calcium citrate;

(v) phosphoserine;

wherein the adhesive strength of the adhesive composition upon curing is greater than 1,000 kPa

and

b) placing the composition into said bone void;

wherein the composition hardens and/or cures in less than about 30 minutes.

17. A method of filling a gap or discontinuity of bone resulting from a congenital condition, trauma, inappropriate healing, a resection of bone, or a procedure involving cutting or segmentation of bone in order to change its size, shape, or contour, the method comprising:

a) preparing an adhesive composition comprising:

(i) a multivalent metal salt selected from one of tetracalcium phosphate or tricalcium phosphate;

(ii) an aqueous medium;

(iii) citric acid or malonic acid;

(iv) calcium citrate;

(v) phosphoserine;

wherein the adhesive strength of the adhesive composition upon curing is greater than 1,000 kPa

and

b) placing the composition into said gap or discontinuity;

wherein the composition hardens and/or cures in less than about 30 minutes.

18. The method of claim 17 , wherein the composition is allowed to remain undisturbed until resorption of the composition by the bone occurs.

19. A method of repairing a defect in a tooth, the method comprising:

a) preparing an adhesive composition comprising:

(i) a multivalent metal salt selected from one of tetracalcium phosphate or tricalcium phosphate;

(ii) an aqueous medium;

(iii) citric acid or malonic acid;

(iv) calcium citrate;

(v) phosphoserine;

wherein the adhesive strength of the adhesive composition upon curing is greater than 1,000 kPa; and

b) placing the composition into or onto said tooth;

wherein the composition hardens and/or cures in less than about 30 minutes.
