The effect of amount variation of E glass fiber on the flexural Strength of denture base materials

الملخص

Removable denture each complete or partial are used for the replacement of missing. Because of that, fracture is a common clinical occurrence, which mostly occur in the midline at the base of the dentures, Flexural strength, transverse strength, or modulus of rupture. As this property is variously called, is a strength test of a bar supported at each end, or a thin disk supported along a lower support circle, under a static load. On the flexural strength E-glass, fiber reinforced acrylic denture base. This study was using E-glass fiber (Everstick C&B, Turku, Finland), divided into 2 group, include 1 groups of 1 strep E-glass fiber and groups of 2 strep E-glass fiber. Measurement of flexural strength used the universal testing machine. The results were analyzed by t-test. The result of t-test shows there were  significant differences according to amount because the value of P = .001, p<0.05. . In conclusion, there were effects of amount on flexural strength of E- glass fiber.
