The aim of this study was to evaluate the reinforcing effects of glass fiber meshes with different content and structures on auto-polymerized pour-type denture base resin. The reinforcements were two types of glass fiber meshes; SES mesh(SES: SES 1108, INNO Dental Co., Ltd., Korea) and Glass cloth(GC: Glass cloth R 326, Hankuk Fiber Co., Korea). GC groups were prepared in two layers(GC 2), three layers(GC 3), and four layers(GC 4). Auto-polymerized pour-type resin(PRESS LT; retec, Rosbach, Germany) was used as the denture base resin. The specimen(64×10×3.3 mm) was prepared by locating each reinforcement at the tension side of the three-point bending mode. Control group was prepared without any reinforcement. The flexural properties of the specimen were measured by an universal testing machine at a crosshead speed of 5 mm/min. The results were evaluated with 1-way ANOVA, and the Duncan"s multiple range test(α=0.05). The flexural strength and toughness of all the glass fiber reinforced groups were significantly higher than the control, except GC 2(P<0.05) and GC 3 showed the highest toughness(P<0.05). The flexural moduli of all the glass fiber reinforced groups were significantly higher than the control(P<0.05). SES(4.36 vol%), GC 3(5.34 vol%) and GC 4(7.39 vol%) were effective in reinforcing the flexural properties of the denture base resin and GC 3 was most effective. Content of the glass fiber reinforcement is considered to be a more important factor than the structure.
