  • Composite and its use
    Patent number: 6248344
    Abstract: A porous composite suitable for filling a recess or a through-passing hole in an implant. The composite includes particles A prepared from a bioactive material and particles B prepared from a non-bioactive material or weakly bioactive material, which is sintratable with the bioactive material, such that particles A and particles B have been sintered together to a porous composite. Particles A and particles B are essentially homogeneous in size. Also disclosed is an implant which contains a core and the composite.
