Flexural Strength of Acrylic Resins Polymerized by Different Cycles
Despite the large number of studies addressing the effect of microwave polymerization on the properties of acrylic resin, this method has received limited clinical acceptance. This study evaluated the influence of microwave polymerization on the flexural strength of a denture base resin. A conventional heat-polymerized (Clássico), a microwave-polymerized (Onda-Cryl) and a autopolymerizing acryl...
متن کاملComparative study of flexural strength of four acrylic resins before and after thermocycling process
Objectives Acrylic resins are one of the most important denture base materials in dentistry due to their favourable mechanical and physical properties. The purpose of present study is to compare 4 available acrylic flexural strength properties before and after thermocycling. Methods Acrylic resin specimens of Meliodent (Heraeus Kulzer, Hanau, Germany), Vertex (Vertex-dental BV, Zeist, Netherla...

متن کاملThe effect of TiO2 and SiO2 nanoparticles on flexural strength of poly (methyl methacrylate) acrylic resins.
PURPOSE TiO(2) and SiO(2) nanoparticles are products of nanotechnology which have been incorporated to acrylic resins (AR) in order to induce antimicrobial properties. However, as additives they can affect the mechanical properties of the final product. The aim of this study was to survey the effects of TiO(2) and SiO(2) nanoparticles on flexural strength (Fs) of poly (methyl methacrylate) acry...
متن کاملEffects of Addition of Aluminum Oxide on Flexural Strength and Hardness of Acrylic Resins
Purpose: Acrylic dentures frequently fracture during service due totheir poor strength characteristics. The aim of this study was to evaluate the effects of adding 5%, 10% and 15% aluminum oxide powder on the flexural strength, surface hardness of a conventional heat-polymerized acrylic resin. Materials and methods: One of the commonly used conventional heat cure denture base resin (DPI) and hi...
