Chicken eggshell contains a high mineral compound, so it is suitable to use as nanoparticle filler. In this research, preparation of denture base with nanoparticle chicken eggshell filler and the variation of filler concentration was 0, 10, 20, 30 (% wt). Preparation of matrix acrylic denture base was processed by mixing powder of the acrylic resin and liquid monomer with the weight ratio 2:1, after that matrix is mould in a cuvette, then polymerized by boiling in water at 75°C for 90 minutes, after 90 minutes, temperature was raised to 100 °C and left for 30 minutes. Characterizations on denture base samples are included by MOE, MOR, FTIR, XRD and TEM. The best result is the addition with 10% filler, in which the modulus of elasticity test (MOE) shown the elasticity of sample are 2.571 GPa, and modulus of rupture test (MOR) shown the rupture of sample are 48.859 MPa. © School of Engineering, Taylor's University
