Hydrophobic 2-methacryloyloxyethyl phosphorylcholine polymer inhibits peri-implantitis-causing bacterial adhesion on titanium materials.

Aims: To prevent peri-implantitis, we investigated the adhesion of periodontopathogenic bacteria to titanium surfaces using a hydrophobic 2-methacryloyloxyethyl phosphorylcholine (MPC) polymer to inhibit adhesion.

Method And Results: We immersed titanium plates (TiPs) coated with a hydrophobic MPC polymer in a bacterial suspension for 30 min or 24 h and measured the number of adherent bacteria. Bacteria adhering to the TiPs were observed using scanning electron microscopy (SEM).
