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 کاملBonded resins in orthodontics.
JL he combination of acid-etching and bonding has led to dramatic changes in the practice of orthodontics. Newman began the revolution in orthodontics with the advent of epoxy-bonded attachments. Bonding has evolved and now is used for; placement of attachments, various types of retainers, and resin build-ups which address tooth size and shape problems encountered during orthodontic treatment. ...
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 کاملEffect of Post-polymerization Heat Treatments on the Cytotoxicity of Two Denture Base Acrylic Resins
INTRODUCTION Most denture base acrylic resins have polymethylmethacrylate in their composition. Several authors have discussed the polymerization process involved in converting monomer into polymer because adequate polymerization is a crucial factor in optimizing the physical properties and biocompatibility of denture base acrylic resins. To ensure the safety of these materials, in vitro cytoto...
متن کاملIn vitro cytotoxicity of self-curing acrylic resins of different colors
OBJECTIVE The aim of this study was to assess the in vitro cytotoxicity of acrylic resins of different colors over time. METHODS Specimens were divided into 4 groups (n = 6) according to the color of the acrylic resin (Orto Class, Clássico, Campinas, São Paulo, Brazil): Group 1, clear acrylic resin; Group 2, pink acrylic resin; Group 3, blue acrylic resin; and Group 4, green acrylic resin. Al...
