Abstract

The subject of the present work is the synthesis of polymeric biocompatible materials based on methyl methacrylate (MMA) copolymers chemically modified by quaternization for use in dental prosthetics. Two copolymers were used, methyl methacrylate – diethylaminoethyl methacrylate (MMA-DEAEMA) and methyl methacrylate – chloroethyl methacrylate (MMACLEMA). The former presents tertiary amino groups and was quaternized using methyl iodide. Triethyl amine was used for the quaternization of the latter. For both of the copolymers, the quaternization was performed either in homogeneous media, or at the surface of the hardened cements. Cytotoxicity and cellular adherence tests were performed in order to confirm the appropriateness of the resulting products in dentistry..
