The bioactivity evaluation of bioactive glass coated titanium surface with simulated body fluid

For the purpose of reinforce both the bioactivity and mechanical strength of implant material, which recovers bone defects, bioactive glass is coated on the surface of titanium substrate. To evaluate the function of bioactibity, immersion test in simulated body fluid is carried out and confirmed the performance of this material, that the apatite precipitates on the surface of coated glass in two days. This coating method of bioactive materials is effective for the reinforcement of bioactivity for metal implants.
