1. A method for forming a ceramic implant having a rough surface texture, the method comprising:

  • a. forming a green body of a first ceramic composition;

    b. reducing the green body thereby forming ceramic fragments;

    c. filling a mold with a second ceramic composition and compressing the second ceramic composition to a predetermined pressure to form a ceramic base;

    d. adding the ceramic fragments to the mold and forming an outer layer over at least a portion of the ceramic base;

    e. applying pressure to the mold to compress the outer layer onto the ceramic base and to form a green assembly; and

    f. sintering the green assembly to form a ceramic implant having a rough surface texture.
