1. A composite material suitable for use in dentures or dental implants, 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.
