Abstract:BackgroundThe second rule of the 4Rs concept (Reduce, Reuse, Recycle, and Recover) was applied in this study using recycled acrylic resin to improve the hardness and study the effect of aging on the hardness of heat cured denture base resins.MethodForty heat‐cured acrylic resin samples were prepared and divided into control and modified groups. The hardness was tested using a type D durometer hardness tester for evaluating the effect of the thermal aging process on the hardness in the control and modified grou… Show more
