Abstract:
An implant produced bya. forming a mixture of a calcium phosphate composition and a binder;b. selectively fusing the binder to form an implant green part; andc.sub.1. infiltrating the implant green part; orc.sub.2. sintering the implant green part to form an implant,whereinthe calcium phosphate composition does not decompose to produce water during step b, andthe implantreplicates a naturally complex bone geometry,has a complex three-dimensional shape with a well-defined cavity, the cavity replicating internal complex bone geometry,has a controlled, interconnected porosity, andhas a mole ratio of calcium to phosphorus of 0.5 to 1.
