The aim of this study was to investigate the effect of various curing methods on the biaxial flexural properties of denture base resins. The following heat-curing denture resins were examined: VT (Vertex RS), PD (Paradent 20), and LU (Luciton 199). Denture base resin disk specimens (19.5±0.05 mm in diameter and 1.95±0.05 mm in thickness) were prepared with the following methods: boiling in water bath (BW), heating in air (HA), and microwave polymerization (MP). After storage in 37°C water for 48 h, the biaxial flexural test of denture base resin disks was conducted according to ASTM C1499 at a loading rate of 5 mm/min. Overall, the biaxial flexural properties of resins were significantly influenced with the resin materials used or the polymerization methods, and also their interaction was significant (P<0.05). The biaxial flexural strength and modulus of VT resin prepared by BW were significantly higher than those by HA or MP methods (P<0.05). The biaxial strength of VT was significantly lower than those of PD and LU, regardless of curing methods. Polymerization methods did not produce any significant difference in the biaxial properties of PD and LU. In conclusion, the three polymerization methods, BW, HA, and HA can be successfully used to fabricate denture base without compromising in their flexural strength and modulus.
