In this paper, a combination of a ceramic mixture with a polymer was developed to be used as a substitute for damaged bones or teeth. Overlays were prepared using the manual mixing method, followed by the use of ultrasound technology to ensure uniform distribution of the powder within the polymer. The polymer (PMMA) is supported with a ceramic powder (HAMgO) prepared using an effective mechanical mixing method and component than hydroxyapatite (HA) is a principle inorganic component of human hard tissues such as teeth and bones and metal nanoparticle magnesium oxide (MgO), which represents the additive to the polymer (PMMA). The percentage used for reinforcement, starting from (1% - 4%). The results of the tests showed mechanical corrosion or the so-called where wear is decreased for the reinforced polymeric composites as the corrosion rate decreased to less than half at 4%. Likewise, the results of the particle hardness examination showed a successive increase in the percentages compared to the polymer base material. The results of the durability of compressibility and Young’s modulus showed a direct increase with the increase in the percentages of the added ceramic powder.
