Abstract
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.
Claims7
A method for forming and polishing a composite denture, comprising:
- fitting a patient for a denture base,
- mixing a powder comprising nanodiamonds having a particle size of about 20 to 40 nm with methyl methacrylate resin powder to form a mixture,
- casting the mixture into a mold, and
- polymerizing the mixture to form the denture base comprising poly(methylmethacrylate) PMMA composite material, and
- polishing the denture base first with a tungsten carbide bur then with a rubber top bur;
- wherein the PMMA composite material, comprises:
- 0.1 to 1.0 wt. % of the nanodiamonds based on a total weight of the PMMA composite material,
- wherein the PMMA composite material has a molecular weight of 50,000 to 1,000,000 g/mol,
- wherein the PMMA composite material is porous having pores 80 to 100 μm in size,
- wherein the nanodiamonds fill pores of the PMMA composite material,
- where the nanodiamonds are only in the pores on the PMMA composite material, and
- wherein the PMMA composite material has a surface roughness (Ra) of no more than 0.2 μm.
