Accelerating and improving the process of osseointegration is a research hotspot of oral implantology, and electrical stimulation of osteogenesis is one of the research directions. In view of the bone"s piezoelectric properties and the defects of exogenous electrical stimulation, the application of piezoelectric materials to generate endogenous electrical stimulation to promote osteogenesis is of great significance. As an environmental-friendly lead-free piezoelectric material, barium titanate has a piezoelectric effect in the tetragonal phase. Especially it has good biocompatibility and can promote bone formation under load conditions. Here we used anodic oxidation technology and hydrothermal reaction to construct a barium titanate piezoelectric coating on the titanium surface. By optimizing the experimental parameters and setting the limit concentration, we explored the synthesis conditions of the tetragonal barium titanate coating.Meanwhile, the piezoelectric potential of coating particles was verified by finite element simulation. By modifying the surface of the dental implant, we hope to provide a new method to promote implant osseointegration.
