| Résumé : |
New abrasive materials for dental prosthesis polishing were developed from
two residual sources: carbide lime, a by-product of acetylene production primarily composed of calcium hydroxide, and eggshell powder, which is rich in carbonates. Both materials predominantly consist of calcite and exhibit cohesive powder characteristics. After grinding, these new abrasive materials achieve a fine grain size distribution ( powder and 20-80% by weight of eggshell powder and carbide lime, significantly reduces surface roughness. Additionally, this mixture enhances the whiteness and brilliance of the dental prosthesis surface. |
