Abstract: Focusing on the research focus of bone repair materials and in view of the problem of limited osteogenic ability of titanium implants, an exploratory and innovative comprehensive experiment was designed by introducing new technologies and new materials to study the modification and osteogenic properties of titanium implants. Tea polyphenol functionalized and reduced graphene oxide (TPG) with osteogenic properties was deposited on titanium implants by electrochemical deposition method. Modified titanium implants with different TPG content were obtained by controlling different deposition time. In addition, the osteogenic properties of the modified titanium implants were evaluated by cell adhesion and proliferation experiments. The results showed that modified titanium implants with different TPG content were successfully obtained by controlling the deposition time. The modified titanium implants deposited for 5 minutes are more conducive to the adhesion of osteoblasts and promote the proliferation of cells, which lays a theoretical foundation for the modification and application of titanium implants.
