Abstract

A biomimetic composite material includes a bioactive cement material, an autologous dentin matrix, and an inorganic nano-reinforcement material. A dental implant includes a body including a biomimetic composite material, wherein the biomimetic composite material includes a bioactive cement material, an autologous dentin matrix, and an inorganic nano-reinforcement material.

Claims (17)

1. A dental implant, comprising:

a body comprising a biomimetic composite material,

wherein the biomimetic composite material comprises processed dentin from an extracted tooth and a bioactive cement.

2. The dental implant of claim 1 , wherein the processed dentin comprises dentin particles.

3. The dental implant of claim 1 , wherein the bioactive cement comprises a calcium silicate based dental cement.

4. The dental implant of claim 1 , wherein the body is formed entirely of the biomimetic composite material.

5. The dental implant of claim 1 , wherein the body comprises a core and an outer surface layer that is disposed over at least a portion of the core.

6. The dental implant of claim 5 , wherein the core is formed at least substantially of the bioactive cement and the outer surface layer is formed of the biomimetic composite material.

7. The dental implant of claim 6 , wherein a thickness of the outer surface layer is between about 500 microns and about 1500 microns.

8. The dental implant of claim 6 , wherein the outer surface layer covers at least substantially all of the core.

9. The dental implant of claim 6 , wherein the dentin comprises from about 10 percent to about 50 percent by weight of the total biomimetic composite material.

10. The dental implant of claim 1 , wherein the dentin comprises from about 10 percent to about 50 percent by weight of the total biomimetic composite material.

11. The dental implant of claim 1 , wherein the biomimetic composite material comprises dentin particles, in powder form, mixed with the bioactive cement.

12. The dental implant of claim 2 , wherein the dentin particles have a particle size between about 50 microns and about 1500 microns.

13. The dental implant of claim 1 , wherein the dentin comprises a plurality of dentin particles with each particle have a multitude of exposed dentinal tubules, the biomimetic composite material being defined by micro-mechanical bonding of the bioactive cement to the dentin particles as a result of flow of the bioactive cement into the dentinal tubules.

14. The dental implant of claim 1 , wherein a final shape and size of the body are selected in view of an image of the tooth that is extracted and mimics the shape and size of the extracted tooth.

15. The dental implant of claim 1 , wherein the bioactive cement comprises a dental cement selected from the group consisting of: a calcium silicate-based cement, a mineral trioxide aggregate (MTA), and a glass ionomer cement.
