The development of high impact strength denture-base materials

Radish Oil Addition effect on some properties Of Heat Cure Acrylic resin

“…It had explained by oil elastomer, which acts as a plastifying agent and decreases the glass transition temperature and elasticity module of resin matrix when added, resulting in a less stiff material at ambient temperature [11,12]. This low elasticity module generates a larger resilience module, increasing the material's capacity to absorb energy and the deflexion force applied [13,14]. However, the non-significant difference in impact strength values of this study can be attributed to the small proportion of oil elastomer because the added oil elastomer concentration was directly proportional to the resistance to impact strength of the denture base material.…”

Flexural strength of polymethyl methacrylate copolymers as a denture base resin

“…Several studies are reported to have improved the mechanical properties of PMMA by chemical modification, such as by the addition of copolymer structures into the resin for the purpose of creating a rubber phase in the resin matrix. This resin was called a high-impact resin 5,9,17,18) . Rodford 5) was the first to present this method using low molecular weight butadienestyrene rubbers (butadiene-styrene b-copolymer) to strengthen PMMA denture base polymers.…”

Comparative effects of denture cleansers on physical properties of polyamide and polymethyl methacrylate base polymers

“…This may be the strong surface character due to its crosslinking structure 16,17) . Since Vlp polyamide resin had a higher initial surface roughness, roughness increased after the immersion.…”
