This study aimed to investigate the reinforcing effect of two kinds of glass fiber, Quarts SplintTM Mesh and SES MESH® and to evaluate the effect of the thermocycling on the transverse strength of the denture base and on the reinforcing effect of the reinforcements. 20 specimens of the size of 2.5 × 10.0 × 65.0 mm were fabricated for each group; control group, metal mesh reinforcement group, Quarts SplintTM Mesh reinforcement group and SES MESH?? reinforcement group. To find the difference made by the thermocycling, 10 specimens of each reinforcement group were treated by thermocycling. 3-point bending test was performed to measure the transverse strength of the denture base resin. The specimens reinforced with SES MESH® and Quarts SplintTM Mesh showed significantly higher transverse strength than the control group (P<.05), and significantly lower transverse strength than the specimens reinforced with the metal mesh (P<.05). Thermocycled specimens were lower in transverse strength than non-thermocycled specimens in the control group, metal mesh group, Quarts SplintTM Mesh group and SES MESH® group, however significant difference (P<.05) was found only in the control group.
