| Research Abstract |
A simple one-pot method for preparing a new implant was established.Strontium ions and zinc ions as bone formation factor are released gradually from clinical implantsurface. The surface treatment method was to use tetra-hydroxy zinc acid (Zn(OH)_4^<2->) or strontiumhydroxide and to immerse the implant the chemical solution at 60～70 ℃. Bone bonding strengthbetween the femur and fabricated implant were studied. It was found that the fabricated implantsexhibited higher bone fixation than clinical implant.
