A process for the preparation of a spatial structure, - implant consisting of pure titanium or titanium alloys with a its surface of at least partially covering open-mesh, three-dimensional spatial lattice structure with a mesh size in the range of 1,5 mm to 6 mm, in which first of all under application of the metal powder - injection molding (mim) a green body is produced, the green compact by debindering to a brown compact is deformed, and wherein by the sintering of the brown compact is produced, the finished implant,characterized by the,that only the portions forming the three-dimensional spatial lattice structure consisting of pure titanium or titanium alloys - by metal powder injection molding, which, by means of a binder removal of seedlings become to brown be processed and to a massive implant body consisting of pure titanium or titanium alloys be arrested, andthat the implant, by sintering of the implant base body with the seedlings become release brown is completed.
