Abstract

Embodiments described herein are related to pellets that are placed within an extraction site that is in need of bone augmentation and preservation. The pellets are typically cylindrical in shape and comprise a material and a polymer coating. The goal of the pellets are to encourage sufficient new bone growth that jaw bone deterioration is prevented. The pellets create, arrange, and assemble an ideal growth environment for new bone growth to rapidly grow and preserve the original contours of an individual'"'"'s jaw bone.

Claims

1. A pellet for performing bone augmentation and preservation, said pellet comprising:

an inner material having a mesh-like structure and consisting of a composite material comprising a bioceramic material and a bone morphogenic protein for causing new bone growth in a desired area, wherein said mesh-like structure is formed in a woven, mesh-like manner configured to allow new bone growth to grow throughout said inner material; and

a polymer coating completely surrounding and covering said inner material.

2. The pellet of claim 1, wherein said pellet is cylindrical.

3. The pellet of claim 1, wherein said polymer coating is a bio-resorbable polymer.

4. The pellet of claim 1, wherein when said pellet is placed in an edentulous ridge said pellet facilitates ridge preservation.

5. The pellet of claim 1, wherein when said pellet is placed on an edentulous ridge said pellet facilitates ridge augmentation.

6. The pellet of claim 1, wherein said bone morphogenic protein comprises a protein substance.

7. The pellet of claim 1, wherein said polymer coating is a polylactic acid.

8. The pellet of claim 1, wherein said polymer coating is a hydrogel.

9. The pellet of claim 1, wherein said polymer coating is a composite coating.

10. A pellet for performing bone augmentation and preservation, said pellet comprising:

an inner material having a mesh-like structure and consisting of a composite material comprising a bioceramic material and a bone morphogenic protein for causing new bone growth in a desired area, wherein said mesh-like structure comprises a fabric-like pattern formed using a three-dimensional printing device; and

a polymer coating completely surrounding and covering said inner material.

11. A pellet for performing bone augmentation and preservation comprising:

a first material for causing new bone growth, where the first material comprises a first composite material consisting of a bioceramic material and a bone morphogenic protein, wherein said first material comprises a fabric-like pattern formed using a three-dimensional printing device; and

a second material for preventing contamination of the first material, where the second material completely surrounds the first material and comprises a second composite material.

12. The pellet of claim 11, wherein the second composite material comprises at least one collagen felt material.

13. The pellet of claim 11, wherein the second composite material comprises at least polymer material.

14. The pellet of claim 11, wherein the pellet is formed in a cylindrical shape.
