摘要: Three methods for the production of Polyethylene glycol (PEG) coatings on titanium are compared, i.e. plasma polymerization, electrodeposition and silanization. The compared deposition presented similar wettability (hydrophilic coatings), chemical composition assessed by XPS thickness around 1 nm. lowered albumin adsorption a decreased fibroblast, Streptococcus sanguinis Lactobacillus salivarius adhesion. Immobilization cell adhesion peptide (RGD) higher fibroblast no alteration bacterial adhesion, giving three biofunctionalization dental implants. feasibility each methodology is in terms process parameters order to provide guide election methodology.
