Abstract
In this study we evaluated fiber reinforced posterior hybrid resin. Two fibers (E glass, polyethylene), bonding agents (modeling liquid, DE bonding liquid) and three different lengths of fibers (20, 30, 40 mm) were used. Moreover, the influence of the fiber bundle inside the posterior hybrid resin on the bending (flexural) strength of the test specimen was studied. The bending strength of the posterior hybrid resin changed from 81.1 to 540.7 Mpa when fibers and additional bonding agent were added. The length of the fiber bundle also affected the bending strength of the test specimen, the strength increasing serially from 95.8 to 415.2 Mpa when 20, 30 and 40 mm long glass fiber bundles were applied. These results suggest the value of fiber reinforcement.
