Recently, Ti-based metallic glasses aim at biomaterials with their high specific strengthand superior corrosion resistance. Their high workability also shows a good performance for massproduction under the energy saving environment. In this study, we started investigation of the designof Ti-based metallic glasses with the restricted alloying elements for biocompatibility andcharacteristic evaluation of the optimized Ti-based metallic glasses with higher glass forming abilityfor dental implants. These Ti-based metallic glasses do not contain Al, V and Ni elements which arewell known to be neurotoxicity and cytotoxicity for human body. Current medical reports ofimpracticability by these elements have been a hot issue in biomaterials science. Newly designedTi-based metallic glasses exhibit good performances. Especially, the optimized Ti-based metallicglass has high corrosion resistance with better passivity in a wide passivation range in simulated bodyfluids at 310K. In addition, biocompatibility of Ti-based metallic glass was also evaluated by cellculture in vitro. Excellent biocompatibility of Ti-based metallic glass show high potentials to beapplied as biomaterials that necrosis of osteoblast (SaOS2) was not detected in this study
