Comparison Study on the Influence of Al2O3 Nanoparticle Size and Ternary Hybrid on Several Properties of a PMMA Denture Composite

In esthetic restorative dentistry, resin composites are generally encountered. Because of their excellent biocompatibility, lack taste, odour, tissue discomfort, and toxicity, insolubility in body fluids, ease use, good clinical/ aesthetic properties, stable colours, optical characteristics, efficient pigmentation, low cost, repairability, they becoming more common. Currently used composite resins have some flaws, particularly inconsistent mechanical properties. For a long time, particles various sizes been as fillers to enhance these prosthodontics, poly(methyl methacrylate) (PMMA) is commonly dental base material. It does, nevertheless, several weaknesses, including strength weak thermal The effects different alumina (Al2O3) on the ethacrylate) denture were determined this experiment. PMMA powder was blended with Al2O3 added methyl methacrylate (MMA).For polymeric materials strengthened (40 nm, 140 nm 0.3-0.8 μm) concentrations, properties studied.Also, synergetic influence three nanoparticle matrix studied.Furthermore, thermogravimetric (TGA) analysis water absorption solubility characteristics prepared also examined. Among most significant be obtained for high mechanic solubility, since attributes aqueous condition oral cavity. Results showed clear optimization, especially size-hybrid composites.
