Colour stability of acrylic resin denture teeth after immersion in different beverages
(2014)
The colour stability of acrylic resin denture teeth in beverages was investigated. A spectrophotometer measured the colour (CIE-L*a*b* system) of all specimens after storage in distilled water for 24 h at 37°C (T0). Specimens ...
Assessment of the flexural strength of two heat-curing acrylic resins for artificial eyes
(2009-12-28)
Prosthetic eyes are artificial substitutes for the eyeball, made of heat-curing acrylic resin, serving to improve the esthetic appearance of the mutilated patient and his/her inclusion in society. The aim of this study was ...
Effect of thermal cycling and disinfection on microhardness of acrylic resin denture base
(2013-04-01)
The purpose of this study was to investigate the effect of thermal cycling and disinfection on the microhardness of acrylic resins denture base. Four different brands of acrylic resins were evaluated: Onda Cryl, QC 20, ...
Resinas para facetas estéticas de próteses fixas. III. Análise conjunta das variáveis alteração dimensional e alteração de peso em função de materiais, condição de armazenamento e tempos.
(1990-12-01)
The authors analysed the simultaneous effects of the dimensional and weight alteration of resins utilized for esthetic facets submitted to warehousing conditions and periods of time. The resins showed different behaviour ...
Effect of accelerated aging on the microhardness and color stability of flexible resins for dentures
(2010-01-01)
Acrylic resins have been widely used due to their acceptable esthetics and desirable characteristics such as easy handling, good thermal conductivity, low permeability to oral fluids and color stability. Flexible resins ...
Water sorption, solubility, and bond strength of two autopolymerizing acrylic resins and one heat-polymerizing acrylic resin.
(1998-10-01)
STATEMENT OF PROBLEM: Because water sorption of autopolymerizing acrylic reline resins is accompanied by volumetric change, it is a physical property of importance. As residual monomer leaches into the oral fluids and ...
In vitro adhesion of Candida glabrata to denture base acrylic resin modified by glow-discharge plasma treatment
(2013-03-01)
This study evaluated the potential of plasma treatments to modify the surface chemistry and hydrophobicity of a denture base acrylic resin to reduce the Candida glabrata adhesion. Specimens (n=54) with smooth surfaces were ...
Effect of disinfectant solutions on a denture base acrylic resin.
(2012-12-01)
The aim of this study was to evaluate the hardness, roughness and mass loss of an acrylic denture base resin after in vitro exposure to four disinfectant solutions. Forty specimens (Clássico, Brazil) were prepared and ...
Effect of microwave disinfection on physical and mechanical properties of acrylic resins
(2008-12-01)
This study evaluated the effect of microwave energy on the hardness, impact strength and flexural strength of the Clássico, Onda-Cryl and QC-20 acrylic resins. Aluminum die were embedded in metallic or plastic flasks with ...
Impact strength of denture base and reline acrylic resins subjected to long-term water immersion
(2011-05-13)
Water may influence the mechanical properties of the acrylic resins. Thus, the effect of water storage on the impact strength (IS) of one denture base (Lucitone 550 - L) and four reline resins (Tokuyama Rebase II - T; ...
