flexural strength of acrylic resin denture bases processed by two different methods

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 the conventional 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 molding technique.
