The present invention provides a porous titanium prosthetic support and a method for preparing the same. The method of the present invention comprises: a step (S1) wherein titanium hydride (TiH2), a freezing medium, and a dispersion agent are mixed to prepare a slurry; a step (S2) wherein said slurry is poured into a mold and subjected to freeze-forming at the freezing point of said freezing medium to form a frozen form; a step (S3) wherein as said frozen form is maintained at a certain temperature around the freezing point of said frozen form for a certain time, the phenomenon of local remelt is used to induce growth of the coagulation phase, and said freezing medium is removed to form a formed body having porosity; a step (S4) wherein heating is carried out at a certain rate to remove impurities from said formed body; and a step (S5) wherein heat treatment is performed to strengthen said formed body. Accordingly, a porous titanium bone support for prosthesis can be provided wherein pores are formed, having mechanical characteristics including elastic modulus and rigidity similar to those of live bone tissue, and which has chemical stability while preserving biocompatibility, and which also enables the promotion of differentiation and growth. |
