This study investigates the effects of diverse concentrations of zirconium oxide nanofiller powders (2%, 4%, 6%, and 8%) on the transverse and impact strengths of heat-cure polymer resin polymerization. Our approach’s novelty lies in using a novel method developed using pure polymethyl methacrylate. Powder samples of zirconium oxide in various concentrations were blended with hot-cured acrylic resin, which is treated with ideal conditions (L/P) rate of about 1: 3 (v/v), traditional packing method, and short curing cycle. Under two heating program of about 74 °C (90 min) and 100 °C (30 min), polymethyl methacrylate (PMMA) specimens with dimensions of 65× 10× 2.5 mm for transverse strength and 60× 7× 4 mm for impact strength were evaluated. Values for impact stress (J) and transverse stress (MPa) were gathered, tabulated, and statistically analyzed. ANOVA and Tukey’s tests were used to assess the range for the experimental samples. The addition of ZrO2 nanofillers significantly increased PMMA ‘s transverse and impact strengths, suggesting practical applications for denture base materials. These findings highlight the potential of PMMA and 8% weight percent ZrO2 nanofillers as effective options for denture based materials.
