Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A dental orthodontic retainer made from a composite material, wherein the composite material comprises: poly(methylmethacrylate) (PMMA) and 0.5 to 1.0 wt. % nanodiamonds based on a total weight of the composite material, wherein said nanodiamonds have an average particle size of about 30 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 dental orthodontic retainer of claim 1 , wherein the composite material further comprises rubber nanoparticles. 3. The dental orthodontic retainer 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 dental orthodontic retainer of claim 1 , wherein Candida albicans binds to said composite material less than a control or otherwise identical composite material not containing nanodiamonds. 5. The dental orthodontic retainer of claim 1 , consisting of the composite material. 6. The dental orthodontic retainer of claim 1 , wherein the composite material consists of the PMMA and the nanodiamonds.
