Comparison of the Transverse Strength of Six Acrylic Denture Resins
Aim: The aim of this study was to evaluate the transverse strength of three kinds of heat-cured acrylic resin (Meliodent HC, Acron HC, Lucitone 199); one kind of microwave-cured acrylic resin (Acron MC); one kind of visible light-cured resin (Triad VLC); and one kind of self-cured acrylic resin (Meliodent SC). Method: A total of 60 specimens (65 mm x 10 mm x 3 mm) were fabricated, ten from each...
متن کاملIn vitro comparison of autoclave polymerization on the transverse strength of denture base resins.
The aim of this study was to determine the effect of autoclave polymerization on the transverse strength of denture base polymers. To this end, 30 rectangular test specimens were fabricated of two heat-polymerized denture base polymers. The test groups were: (I) control, i.e., conventional water bath to polymerize resins by heat at 100 degrees C for 30 minutes; (II) autoclave polymerization at ...
متن کاملElastic modulus and flexural strength comparisons of high-impact and traditional denture base acrylic resins.
BACKGROUND Fractures of acrylic resin dentures are a common occurrence in clinical dentistry. The denture may be fractured accidentally when dropped or while in service in the mouth due to flexural fatigue. OBJECTIVES The aim of this study was to compare the elastic modulus and the flexural strength between two heat-cured acrylic resins used in denture bases: a high-impact resin (Lucitone 199...
متن کاملImpact strength of denture base and reline acrylic resins subjected to long-term water immersion.
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; UfiGel Hard - U; Kooliner - K; New Truliner - NT) was evaluated. Bars of L were made (60 x 6 x 2 mm) and relined (2 mm) with T, U, K, NT and L. Intact specimens of each material (...
متن کاملFlexural properties and impact strength of denture base resins reinforced with micronized glass flakes
OBJECTIVES To investigate the effect of the addition of glass flakes on physical properties of conventional heat cure denture base resins and to compare it with a high impact strength denture base resin. MATERIALS AND METHODS Test specimens were divided into Group 1 - poly (methyl methacrylate) (PMMA) (Trevalon), Group 2 - Trevalon HI, Group 3 -5% glass flake +95% PMMA (Trevalon), Group 4 -10...
