The objective of this research is to study the effect of various weight fractions (2%, 4%, 6%, and 8%) orange peels powder reinforced with PMMA resin on some mechanical properties which were prepared by hand lay-up method, and the utilized in the dental base.  Three kinds of mechanical tests were performed on all samples, including; tensile test, flexural test and impact test. The recorded values of mechanical properties were tabulated and statistically analyzed by using (Origin Lab) program. Turkey and Scheffe tests were used in order to determine the signification between the means of tests group that are statistically significant.  Results show the incorporation of 8% weight fraction orange peels powder with PMMA resin causes significantly increased in modulus of elasticity, flexural strength and flexural modulus, while the sample reinforced with 4% orange peels powder has a maximum of tensile strength. The value elongation percentage decreased when reinforced with 8% weight fraction orange peels powder compared to the control sample. The impact strength values increased with addition 6% weight fractionof orange peels powder compared to the control sample, while the impact strength values start to decline in samples reinforced with 8% of orange peels powder. Statistically analyzed, shows that the tensile strength, modulus of elasticity, flexural strength, flexural modulus and impact strength of PMMA resin strengthened by orange peels powder is improved for being a value Sig = 1. Thus, the samples reinforced orange shell powder into PMMA resin are suitable to be used as a denture base.
