Influence of Processing Techniques on Microhardness and Impact Strength of Conventional and Reinforced Heat Cured Acrylic Resin: A Comparative Study

This study determined and compared the influences of various processing techniques including air circulating oven (ACO), dry heat (DHO) water bath (WB) on impact strength (IS) microhardness (HV) conventional cure acrylic resin (CHCAR) rubber reinforced (RRHCAR). Samples were fabricated using CHCAR (control Group A; n=114) RRHCAR (experimental B; n=114). A B further divided into subgroups according to techniques: ACO, DHO WB (n=38 each) for both testing variables (n=19 each). Charpy machine Vickers tester utilized. Analysis variance was applied determine presence significant differences among while P-value ≤ 0.05 considered as significant. Water (P-value [0.001) technique (p-value showed between groups� microhardness. Microhardness group a difference 0.002) when processed by ACO. Impact micro hardness improved in ACO comparison technique. Rubber revealed improvement The exhibited highest materials. Dry values resin.
