Flexural strengths of reinforced denture base resins subjected to long-term water immersion
Objective This study evaluated the flexural strengths of reinforced denture base resins subjected to long-term water immersion. Materials and methods Acrylic denture base resin reinforced with metal wire or glass fiber-reinforced composite (FRC), and without reinforcement were tested. Bar-shaped specimens were fabricated. Half of the specimens were stored in 37 °C distilled water for 50 hours (...
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...
متن کاملFlexural and fatigue strengths of denture base resin.
STATEMENT OF PROBLEM Mechanical properties of denture acrylic resins are important for the clinical success of multiple types of prostheses. Acrylic resins must be strong and resilient so as to withstand impact. Few studies utilize cyclic loads to characterize material response to repeated stress. PURPOSE The purpose of this study was to evaluate static and dynamic flexure properties of a var...
متن کاملFailure strengths of denture teeth fabricated on injection molded or compression molded denture base resins.
STATEMENT OF PROBLEM Denture tooth fracture or debonding remains a common problem in removable prosthodontics. PURPOSE The purpose of this in vitro study was to explore factors determining failure strengths for combinations of different denture tooth designs (shape, materials) and injection or compression molded denture base resins. MATERIAL AND METHODS Three central incisor denture tooth d...
