Study of the surface hardness and modulus of elasticity of conventional and microwave-cured acrylic resins.
The aim of this study was to evaluate the following acrylic resins: Clássico, QC-20 and Lucitone, recommended specifically for thermal polymerization, and Acron MC and VIPI-WAVE, made for polymerization by microwave energy. The resins were evaluated regarding their surface nanohardness and modulus of elasticity, while varying the polymerization time recommended by the manufacturer. They were al...
متن کاملRelease of methyl methacrylate from heat-cured and autopolymerized resins: cytotoxicity testing related to residual monomer.
Three heat-cured and three autopolymerized acrylic denture bases with different mixing proportions and/or processing methods were investigated for the amount of residual monomer content and methyl methacrylate (MMA) released into saliva after incubation during the first and second 24 hours after processing. A corresponding range of concentrations of MMA was also used to test for cell cytotoxici...
متن کاملComparison of Water Sorption of Two Injection Acrylic Resins with a Conventional Pressure-Packed Acrylic Resin
Background and Aim: Water sorption is one of the most important properties that affects the quality of a prosthesis, and subsequently, the quality of treatment, and pa-tient’s quality of life. The aim of this study was to determine and compare the water sorption of two types of poly methyl methacrylate (PMMA) using the injection-molding systems with a traditional acrylic resin base material. M...
متن کاملWater Sorption and Flexural Strength of Thermoplastic and Conventional Heat-Polymerized Acrylic Resins
OBJECTIVES The aim of this study was to assess and compare the water sorption and flexural strength of thermoplastic and conventional acrylic resins. MATERIALS AND METHODS Water sorption and flexural strength were compared between a thermoplastic modified polymethyl methacrylate (PMMA) denture base resin (group A) and a heat-polymerized PMMA acrylic resin (group B) as the control group (n=10)...
