PROBLEM TO BE SOLVED: To enhance the mechanical strength, quicken the binding to the bone and make keepable the stability over a long period of time by dipping a base material made of titanium metal in an alkali solution, sintering the same, and dipping the same in a calcium hydroxide solution. SOLUTION: For example, a pure titanium plate is used as a base material, dipped in about 5 mol/l of NaOH water solution and then washed with pure water. The material is dried to form a coat composed of a titania phase and a sodium titanate gel phase on the surface of the base material. The obtained material is sintered at about 60 deg.C for about one hour to alterate a part of the sodium titanate gel phase to a sodium titanate phase. Subsequenty, the material is dipped in a calcium hydroxide water solution with the concentration of 0.1-20M mol/l, and then washed with water and dried to obtain an implant material for an organism. Thus, apatite can be formed in a short time, and the speed of connection to the bone can be increased. |
