Evaluation the Effect of Fiber Reinforcement Materials on Flexural Strength of Heat Cured Denture Based Resin Materials
Abstract
Aims: To assess the effect of fibres reinforcement materials on flexural strength of heat cured denture-based resin. Materials and Methods: Sample of heat-cured acrylic resin were created and divided into: Control group (heat cured with no fibres addition) and two experimental groups (with fibres additive). The flexural strength was evaluated, calculated, and the information was statistically analysed using descriptive statistics, an analysis of variance (ANOVA), and Duncan multiple range tests with p 0.01 in SPSS Version 19. Results: The result showed highly significantly increase of flexural strength, untreated polypropylene fibres showed the highest flexural strength followed by untreated glass fibres. Conclusion: Reinforcement with fibres was an efficient approach for improvement of flexural strength of heat cured PMMA denture base resin.
