[QUOTE="JKraver, post: 361807, member: 13886"] It is still hard acrylic just Ethyl Methacrylate(PEMA) based not Methyl Methacrylate(PMMA= Poly Methyl Methacrylate). Also Doris was asking do you injection process or pack process. Injection on the ivobase/cap can reduce the free MMA monomer to levels generally tolerated by those who are allergic to MMA monomer. Theoretically you could overheat a conventional press pack denture and let it boil longer to reduce these levels, along with a slow cool to hopefully prevent warp, or maybe a cold water quench would be better for warp.
