The effect of aluminum oxide on heat polymerized acrylic resin denture base material to flexural strength and color stability
AbstractPurpose: The purpose of this study was to determine the effect of aluminum oxide addition on heat polymerized acrylic (HPA) resin denture base to flexural strength and color stability. Method: This study was carried out on HPA resin samples without and with the addition of aluminum oxide with a concentration of 0.5%, 1.5%, 2.5%. A bar-shaped sample sized 65 x 10 x 3 mm was used for flexural strength testing and circular-shaped sample with a diameter of 50 mm x 1 mm (no. 80) was used for color stability testing; 24 samples for flexural strength test and 24 samples for color stability test. All samples were immersed in distilled water for 48 hours at 37°C in an incuba-tor. A universal testing machine was used to test flexural strength and a portable colorimeter was used for color stability testing. Conclusion: The addition of 0.5% aluminum oxide significantly increase the flexural strength and has good color stability.
