Abstract
Background and aims. The aim of this study was to compare flexural strength of specimens processed by conventional and injection-molding techniques.
Materials and methods. Conventional pressure-packed PMMA was used for conventional pressure-packed and injection-molded PMMA was used for injection-molding techniques. After processing, 15 specimens were stored in distilled water at room temperature until measured. Three-point flexural strength test was carried out. Statistical analysis was carried out by SPSS using t-test. Statistical significance was defined at P<0.05.
Results. Flexural strength of injection-polymerized acrylic resin specimens was higher than that of theconventional method (P=0.006). This difference was statistically significant (P=0.006).
Conclusion. Within the limitations of this study, flexural strength of acrylic resin specimens was influenced by the mold-ing technique.
