<P>PROBLEM TO BE SOLVED: To provide a biological implant having a kinetic property close to the bone or the tooth and having a function bonding with the bone after embedding the biological implant in the body; and a method for simply producing the biological implant having such characteristic. <P>SOLUTION: This biological implant is provided with a solid section, and a surface layer formed of an object forming the solid section and a bioactive material, having a porous structure and having the bioactive material exposed to the surface at least 0.5% to the surface area. This production method of biological implant includes a process 1 for making porous the surface of a precursor consisting of the object forming the solid section of the biological implant; and a process 2 for immersing the precursor of the biological implant with the porous surface in both of solution containing calcium ions of at least 2M and solution containing phosphate ions of at least 2M with either one of them earlier. <P>COPYRIGHT: (C)2009,JPO&INPIT |
