Abstract: Background improvement of mechanical properties of heat cure acrylic resin with inorganic filler had great attention. The purpose of this study was to evaluate some mechanical properties of heat cure acrylic after the addition of salinated aluminum silicate Al2SiO5 filler in different concentrations. Materials and methods A total 124 specimens were constructed, 30 specimens were prepared from heat cure PMMA without additives (control) and 90 specimens were prepared from heat cure acrylic resin with the addition of salinated Al2SiO5 composite filler which divided into 3test groups according to different percentage (3 %, 5 %, 7 %). Each group was divided into 10 sub-groups according to the test performed which was impact strength, surface hardness and surface roughness. Also for each group, 4 specimens were prepared for FTIR test. Results The results of addition salinated Al2SiO5 particles to PMMA record a highly significant increase in impact strength, surface hardness and surface roughness. For impact strength test, the highest mean value was for specimens containing 3 % Al2SiO5. While for surface hardness test and surface roughness test, there is a marked increase in the mean values as the concentration of fillers increase. Conclusion Within the limitation of this study, it may be concluded that the addition of 3 % Aluminum silicate to heat cure acrylic denture base material improves the impact strength, hardness with slight increases the surface roughness.
