PROBLEM TO BE SOLVED: To provide a bioabsorbable implant having high usability maintaining a shape not only during compensation operation but also until a completion of the compensating operation even while holding excellent bone binding performance and a method for producing the same.SOLUTION: A bioabsorbable implant is formed of bioabsorbable ceramics and satisfies the following conditions and has a porous structure. A method for bioabsorbable implant is characterized by having a granule preparing step of the bioabsorbable ceramics, a granule mixing step of obtaining a granule mixture by mixing a granule and combustible organic particle in which 50% accumulated particle sizes are together 100 μm or less and 300 μm such that the volume ratio of the combustible organic particle is 20% or more and less than 40%, a shaping step of shaping the granule mixture by a pressure of 200 kg/cmor more, and a sintering step of sintering the shaped body. The condition: the volume ratio of pores having a fine pore size of 3 μm to all of pores is 25% or more and less than 80%, a porosity is 30% or more and less than 40%, and a compression strength is 20 MPa. |
