The evaluation of the wettability and surface characterization of titanium implant coated by electrophoretic deposition technique

The long-term success of any dental implants largely depends on how rapid the healing process takes place as well as how safe the integration process with the jaw bone will be. The aim of this current study is to characterize the wettability of orthopedic implant coated with the electrophoretic deposition technique. The novel Hydroxyapatite-Diopside (HA-DI) nanocomposite coats were fabricated via electrophoretic deposition technique. The reactions of the coats that were incubated in the simulated body fluid (SBF) solution were studied to investigate the wettability, and growth of apatite of the coats. The results showed that the bioactivity and wettability values of obtained composite coatings enhanced with increase in DI amounts by up to 30%. The results of the wettability and thermogravimetric analysis (thermal decomposition) of nanocomposite might be an important factor in dental coating applications. The pore volume indicates an increasing trend with higher temperature which is suitable for osseointegradation of prosthesis inside the body. Wettability is an important parameter, and the porous films usually displays a highly hydrophobic character due to the hydrophobic polymer matrix and the air entrapped inside the pores, which results in an increased surface roughness.
