Over the last few decades, a wide variety of dental implants have been successfully placed in jaw bones to restore tooth function. But major challenges still remain in patients with osteoporosis involving compromised osseointegration, and the therapeutic methods is far from optimism. Gallium can directly inhibit bone osteolysis, prevent bone calcium release and augment bone mass, which makes Ga unique among the potential antiresorptive drugs. Silicon, as an indispensable modulator in bone formation, presents its bone anabolic effects, while reduces, at least doesn't increase, bone resorption. We hypothesize that the combination of bone anabolic effects of Si and antiresorptive effects of Ga will result in synergistic effects on the improvement of osteointegration under osteoporotic condition. In our strategy, in order to maximize the efficacy while minimize the side effects of ions, a novel titania mesoporous layer fabricated by electrochemical anodization on the surface of titanium implant will be employed as a promising local drug delivery system. The synergistic effects of Ga and Si on improving osseointegration will be verified by animal experiments, and be furthered by clinical trials. Our hypothesis could help to create an option to improve success rate of dental implants in osteoporotic patients.
