| Outline of Final Research Achievements |
We investigated the effect of promoting the differentiation and proliferation of osteoblasts by preparing a zinc sustained-release titanium (Zn-Ti) framework by modifying zinc complex on titanium surface. It was found that the Zn-Ti mesh can release zinc ions in a sustained manner, and this zinc ion differentiates and proliferates the cells surrounding the material into osteoblasts and further promotes mineralization. In bone formation ability experiments in which bone defects prepared in the rat skull were coated with Zn-Ti mesh, there was a difference in bone regeneration rate between Ti and Zn-Ti used for control, but statistical no significant difference was obtained.
