When the pores are connected together with openings larger than ∼50 µm, cells, not restricted to bone cells, can migrate deep into the porous body to fill whole pores. In this manner, the implant serves as a structural bridge and model...

... network. Ceramics, for the most part, have lower densities than metals because they contain light oxygen, nitrogen, or carbon atoms. Even the lightest atoms, packed in the most open way, give solids with a density of around 1 Mg/m 3 (60 lb/ft 3 ). Materials with lower densities than this are foams...
