Abstract: Background The polymethyl methacrylate is most commonly material used for fabricating removable partial and complete denture. The aim of this study was to evaluate the effect of addition of different concentration of strontium to acrylic denture base on mechanical properties ( transverse strength, impact strength and hardness) some properties of heat cured acrylic denture base material. Materials and Methods For this study, 150 specimens were prepared. The specimens were divided into three groups according to test ( transverse strength test, impact strength test and hardness test), then each group subdivided into 5 group according to concentration of strontium added to polymethyl methacrylate ( 0wt %, 1wt %, 3wt %, 5wt %, 7wt %). The results were analysed by one way ANOVA test. Results the results showed the transverse strength and hardness of all groups with strontium is higher significantly than control group (polymethyl methacrylate without strontium). while the best concentration of strontium added to acrylic to improve mechanical properties is 5wt % Conclusion The acrylic resin denture base material with addition strontium carbonate will improve transverse strength, impact strength and hardness. The best concentration for improve these mechanical properties was 5wt % of strontium
