ABSTRACT
Bone cements are substances used to repair the damaged or diseased areas of bones or to fix a prosthesis in the bones. Generally acrylic cements made of polymers of methylmethacrylate (MMA) are used for cement production. The scientist who first synthesized polymethylmethacrylate (PMMA) probably did not envision that this process would be a significant step in medical science. The pilots of the World War II, who carried some glassy PMMA remnants in their body as a result of shattered cockpit windshields, could not know that they already were a part of in vivo experiments for biocompatibility of polymers.
