Sažetak
Fractures of polymer material are one of the most frequent reasons for the repair of removable dental prostheses. Therefore, there is a constant endeavor to strengthen them, and polymer materials with high resistance to fracture are being developed. The aim of this study is to determine the flexural strength of polymer materials and their reinforcements, and thus give preference to their clinical use. Specimens with dimensions 18 x 10 x 3 mm were tested after polymerization, immersion in water of temperature 37oC for 28 days, and thermocycling, by using the “ short beam” method to determine the flexural strength. Microscopic examination was performed to determine the quality of bonding between the glass fibers and matrix. Common polymer materials (control group) demonstrated the lowest flexural strength, although, when reinforced with fibers they showed higher flexural strength matching that of the tested high impact strength resin. Thermocycled specimens had the highest flexural strength, whereas, there was no difference (P>0.05) between specimens tested after polymerization and immersion in water.
