Effect of Treated Fiber Reinforcement on the Flexural Strength of Heat-Cured Denture Base Resin Materials

Abstract

Aims: This study was carried out to evaluate the flexural strength of heat-polymerized acrylic denture base material that is readily accessible commercially after strengthening with two kinds of saline treatment fibers. Material and Methods: Samples were created using traditional acrylic resin, the same resin that was reinforced with glass and polypropylene fibers, and conventional acrylic resin alone. A 3-point bending test was used to gauge the flexibility of the material, and the findings were then examined using a one-way analysis of variance Results: The flexural strength of all strengthened samples was greater compared to that of standard acrylic resin; those reinforced with polypropylene fibers had the highest flexural strength, followed by those reinforced with glass fibers. Conclusion: Heat-polymerized PMMA denture resin's flexural strength was increased following reinforcing with treated glass or polypropylene fibers, within the confines of the fibers used in this study. These findings might be used as the bases of distal extension partial dentures and temporary fixed partial dentures.
