Abstract- In the dentures industry, materials must be chosen to have goodmechanical properties in order to resist the conditions that may occur in themouth. A study was conducted to assess tensile strength, elasticity coefficient,elongation, flexural strength, flexural modulus with impact properties of polymethyl methacrylate resin as matrix strengthened with cinnamon powder andalso analysing these mechanical properties by using (OriginLab) softwareprogram. The samples of Poly Methyl methacrylate bio composites whichcontaining 2%, 4%, 6%, and 8% weight fractions of cinnamon powder and anunfilled as control sample were fabricated using “hand lay up” method. Theresults indicate that the addition of 8% weight fraction cinnamon powder intoPoly Methyl methacrylate resin improved of ultimate tensile strength, moduluselasticity ,flexural strength, flexural modulus (62 MPa, 3.7 GPa, 96 MPa, 6.4GPa) respectively, compared with the values of pure Poly Methyl methacrylate(51 MPa, 1.5 GPa, 78MPa, 2.0 GPa) respectively. Also can be noted that theelongation at break values decreases with an increase in weight fractions offiller, where the sample (Poly Methyl methacrylate +2% cinnamon) has the bestvalue for elongation compared with samples reinforced (4%, 6% and 8% wt).The impact strength results observe the maximum value was present in thesample (Poly Methyl methacrylate+6% cinnamon). From the results,descriptive, One Way ANOVA statistical analysis and means comparison byused (Scheffe test and Tukey test) for all mechanical properties indicated, turnsout if Sig equals 1 shows that the variance in mean is significant at the level of0.05, whereas Sig is 0 designates that the mean variance is not significant at thelevel 0.05.
