Effect of Post-polymerization Treatments on the Flexural Strength and Vickers Hardness of Reline and Acrylic Denture Base Resins
This study evaluated the effect of water-bath and microwave post-polymerization treatments on the flexural strength and Vickers hardness of four autopolymerizing reline resins (Duraliner II-D, Kooliner-K, Tokuso Rebase Fast-TR and Ufi Gel Hard C-UGH) and one heat-polymerized acrylic resin (Lucitone 550-L), processed using two polymerization cycles (short cycle - 90 minutes at 73 degrees C and 1...
متن کاملShear Bond Strength of Acrylic Denture Teeth to PMMA and Polyamide Denture Base Materials
Introduction: Detachment of denture teeth from denture base is one of the most common reasons for costly denture repairs .This study aimed at evaluating the bond strength of an acrylic denture tooth to polyamide injection-molded thermoplastic denture base material compared with three conventional polymethylmethacrylate (PMMA) denture base resins. Materials and Method: A total of 40 acrylic dent...
متن کاملSpecial Section: Dentistry - An evaluation of the hardness of flexible Denture Base Resins
Nylon denture base material (Lucitone FRS) was studied for its mechanical properties. The study confirmed that flexible denture base material has lower values in terms of hardness.
متن کاملEffect of denture cleansers on color stability, surface roughness, and hardness of different denture base resins
AIM The purpose of this study was to evaluate the effect of different denture cleansers on the color stability, surface hardness, and roughness of different denture base resins. MATERIALS AND METHODS Three denture base resin materials (conventional heat cure resin, high impact resin, and polyamide denture base resin) were immersed for 180 days in commercially available two denture cleansers (...
متن کاملA Comparative Clinical Study of the Effect of Denture Cleansing on the Surface Roughness and Hardness of Two Denture Base Materials
AIM This study aimed to verify the influence of oral environment and denture cleansers on the surface roughness and hardness of two different denture base materials. METHODS A total of sixteen identical removable disc specimens (RDS) were processed. Eight RDS were made from heat-cured acrylic resin (AR) and the other eight were fabricated from thermoplastic injection moulded resin (TR). Surfa...
