Comparison 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 کاملHeat Effect on Viscosity and Curing of Light-Cured Dental Resin and Mechanical Strength of Conventional Dental Composites
Dimethacrylate polymers and silica are most commonly used as matrix resins and fillers for dental composites. Bis-GMA, UDMA are used as base monomers and TEGDMA as a diluent monomer for dental resin preparation. Pure UDMA, mixtures of UDMA:TEGDMA and Bis-GMA:TEGDMA 50:50 and 75:25 were mixed with silanized silica at compositions of monomer:fillers 30:70 and 40:60 (weight ratio). Heat curing of ...
متن کاملEffect of Thermocycling and Polyethylene Fibre Addition on Impact and Transversal Strength of Heat Cured Acrylic Resin Denture Base Material
Background: Heat cured acrylic resin is the most widely used material in the manufacture ofdenture base, but has mechanical properties weakness (transversal strength and impact strength). Alternative to increase the mechanical properties of acrylic resin is the utilization of reinforcing fibre that is polyethylene fibre that has advantage such as good aesthetic, easy to manipulate and increase ...
متن کاملEffects of thermocycling and various drinks on the color stability of heat-polymerized acrylic resin
PURPOSE The discoloration of acrylic resin denture bases may lead to significant esthetic problems. The aim of this in vitro study was to investigate the effects of frequently consumed drinks on the color changes of fresh and aged, heat-polymerized, conventional acrylic resin. MATERIALS AND METHODS Eighty-four, heat-polymerized acrylic resin specimens (4 mm x 5 mm x 30 mm) were fabricated. Ha...
