Thermal Analysis on Acrylic Based Denture Materials
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2017, Vol 1, Issue 7
Abstract
Acrylic is a polymer material made of poly methyal acrylate used as polymer electrolytes, complex polymer preparation and dental base material for fixation. Acylic Polymeric materials reinforced with ceramic compositions provide advantages of high stiffness and strength to weight ratio as compared to conventional denture. The main objective of this work is to study variation in sturctural and physical and chemical transformations such as glass transition and degradations of Acrylic based denture materials such as Acralyn-H, RR Cold Cure material and Quick Ashvin were analyzed by X-ray diffraction, TGA and DTA.Acrylic resins were first utilized as denture base materials. Poly (methyl methacrylate) is the primary base resin used today. Polymerization of poly (methyl methacrylate) may be effected by heating the polymer–monomer mixture in a water bath, by chemical activation at room temperature using a material such as dimethyl-p-toluidine, or by activating the reaction using microwave energy or visible light [1]. Addition polymerization requires the activation of the initiator (benzoyl peroxide) to provide free radicals. Polymerization takes place as the free radicals open the double bonds of the methyl methacrylate, creating a chain reaction where the monomer attaches to polymer free radicals. Barron, Rueggeberg & Schuster [2] stated that the degree of monomer conversion of resin materials is a measure of the carbon double bonds (C=C) converted into carbon single bonds (C–C).
