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 کاملColor stability, water sorption and cytotoxicity of thermoplastic acrylic resin for non metal clasp denture
PURPOSE The aim of this study was to compare the color stability, water sorption and cytotoxicity of thermoplastic acrylic resin for the non-metal clasp dentures to those of thermoplastic polyamide and conventional heat-polymerized denture base resins. MATERIALS AND METHODS Three types of denture base resin, which are conventional heat-polymerized acrylic resin (Paladent 20), thermoplastic po...
متن کاملAcrylic Resin Water Sorption Under Different Pressure, Temperature and Time Conditions
The purpose of this work was to analyze water sorption by polymerized acrylic resins under different pressure, temperature and time treatments. A thermo-cured acrylic resin was used as the denture base (Classico Ltda.) and ethylene glycol di-methacrylate as a cross-linking agent, with processing carried out in a water bath at 73 °C for nine hours. Forty-five samples were prepared following the ...
متن کاملThe Evaluation of Water Sorption/Solubility on Various Acrylic Resins
OBJECTIVES The absorption of water by acrylic resins is a phenomenon of considerable importance since it is accompanied by dimensional changes, a further undesirable effect of absorbed water in acrylic resins to reduce the tensile strength of the material. Solubility is also an important property because it represents the mass of soluble materials from the polymers. METHODS Ten acrylic resin-...
متن کاملBonding of Acrylic Resin Teeth with Denture Base Resin
The debonding of acrylic resin teeth with the denture base resin has been related to several different factors of which contamination of the bonding surfaces with wax has been suggested as the major cause. The purpose of this study was to determine the efficient method of wax removal from denture teeth using hot water at different temperatures ranges. Acrylic rods were used as tooth analogues a...
