Flexural Strength, Water Sorption and Solubility of a Methylmethacrylate-Free Denture Base Polymer Reinforced with Glass Fibre Reinforcement

Abstract

Abstract - A methylmethacrylate-free denture base polymer (Eclipse) in comparison to a conventional denture base polymer (Palapress vario) was evaluated after water saturation and Stick glass fibre reinforcement. The data were analysed with ANOVA at α=0.05. Water-storage caused a decrease in the flexural strength and stiffness of the materials (p>0.05). Conventional denture base material with fibre reinforcement gave highest flexural strength (201.1 MPa) compared to fibre reinforced Eclipse (79.1 MPa) (p<0.05). Water sorption after 76 days was 2,08 % (Palapress vario) and 1,55% (Eclipse). Fibre-reinforcement of methylmethacrylate-free material was not as successful as conventional denture base and needs to be further optimized.
