PURPOSE:To obtain an implant in bone for dental or orthopedic use getting to fit organisms well, having no damages, obtained by molding forsterite or zirconia to give a substrate, attaching calcium phosphate to its, sintering it. CONSTITUTION:Fine powder of raw material of forsterite or zirconia porcelain mixed with an agent eliminable by sintering and a stabilizer is blended with a binder consisting of clay or an organic substance, molded by pressing, casting, etc., it is directly sent to the following process or baked to remove the organic binder. It is immersed in a slip which is obtained by suspending powder of calcium phosphate or a substance to produce calcium phosphate by sintering and together with a binder in water, it is coated by brushing or spraying, dried, and the substrate is sintered at the sintering temperature of the substrate to give the desired member. When the powder of calcium phosphate is blended with carbon powder, powder of organic substance, etc. to vaporize and to be reduced to ashes, the surface of it becomes porous and it gets to fit organisms further. |
