"Poly(methyl methacrylate), commonly abbreviated as PMMA, is a biocompatible synthetic polymer in the acrylate family 1-3. It is a self-curing acrylic resin 4 made of powder and liquid components. PMMA acts as a “grout” that locks the bone and implant together mechanically, without chemical bonding."

"In the medical field, PMMA has been used in 1-3,5:"
"Polymerisation of PMMA starts by mixing the initiator and monomer, an exothermic reaction, into three steps: initiation, propagation, and termination."
"The powder consists of an initiator (di-benzoyl peroxide, BPO), copolymer beads, a radio-opacifier (BaSO4 or ZrO2), and sometimes antibiotics. The liquid component consists of the monomer (methyl methacrylate, MMA), stabiliser, and an activator (dimethyl-para-toluidine, DMPT) 6. To enhance the biological activity of PMMA, it is often combined with various compounds such as hydroxyapatite (HAp), carbon nanotubes, and natural polymers, including chitosan and collagen 1."

"PMMA is bioinert and does not bond or chemically integrate with bone tissue at the implant site. Therefore, the host bone and bone cement exhibit weaker interactions with microinstability during normal activities, resulting in the formation of tiny wear debris that can induce osteolysis. PMMA shrinkage can also occur. These can lead to aseptic loosening or potential displacement of the bone cement implant 1,3."
