Denture or removable dental prosthetic made from composite material
A curable composite material containing nanodiamonds, denture bases and other dental prosthetics made from the composite material and methods for treating dental stomatitis using these prosthetics.
1. A partial denture, full denture, or other removable dental prosthetic comprising a composite material, comprising:
poly(methylmethacrylate) (PMMA) and
0.1 to 1.0 wt. % nanodiamonds based on a total weight of the composite material,
wherein said nanodiamonds have an average particle size ranging from 20 to 40 nm;
wherein the PMMA has a molecular weight of 50,000 to 1,000,000 g/mol,
wherein the composite material is porous having pores 80 to 100 μm in size,
wherein the nanodiamonds fill pores of the composite material,
where the nanodiamonds are only in the pores on the composite material, and
wherein the composite material has a surface roughness (Ra) of no more than 0.2 μm.
2. The partial denture, full denture, or other removable dental prosthetic of claim 1 , wherein the composite material further comprises rubber nanoparticles.
3. The partial denture, full denture, or other removable dental prosthetic of claim 1 , wherein the PMMA has a molecular weight as measured by gel permeation chromatograph (GPC) of 300,000 to 1,000,000 g/mol.
4. The partial denture, full denture, or other removable dental prosthetic of claim 1 , wherein the nanodiamonds in the composite material have an average particle size of about 30 nm and the nanodiamonds are uniformly distributed in the composite material so that the density of nanodiamonds between cm 3 different volumes of composite does not vary by more than 10%.
5. The partial denture, full denture, or other removable dental prosthetic of claim 1 , comprising 0.25 to 1 wt. % nanodiamonds based on a total weight of the composite material.
6. The partial denture, full denture, or other removable dental prosthetic of claim 1 , wherein the nanodiamonds have an average diameter of about 30 nm.
7. The partial denture, full denture, or other removable dental prosthetic of claim 1 , wherein the nanodiamonds are present in an amount ranging from 0.5 to 1 wt. % of the composite material.
8. The partial denture, full denture, or other removable dental prosthetic of claim 1 , wherein Candida albicans binds to said composite material less than a control or otherwise identical composite material not containing nanodiamonds.
9. The partial denture, full denture, or other removable dental prosthetic of claim 1 , consisting of the composite material.
10. The partial denture, full denture, or other removable dental prosthetic of claim 1 , wherein the composite material consists of the PMMA and the nanodiamonds.
11. The partial denture, full denture, or other removable dental prosthetic of claim 1 , which is in the form of a partial denture.
12. The partial denture, full denture, or other removable dental prosthetic of claim 1 , which is in the form of a full denture.
