Calcium phosphate (CaP) bioceramics are popular implant material for bone repair, substitution or augmentation in orthopaedic and maxillofacial surgery. CaP materials exhibit biocompatibility with hard tissue and promote bone regeneration proceses by release of calcium and phosphate ions. CaP ceramics are widely used in several clinical applications in different forms. There are various techniques to produce porous calcium phosphate ceramics. Introducing additional functions to the ceramic materials provides the possibility in applications as drug or cell delivery systems. Each of the applications requires specific microstruclutal and compositional architecture of all kind of elements. The newly developed technology for the preparation of porous calcium phosphate ceramics will be presented. The viscous slurry foaming using ammonium bicarbonate as foaming agent is an promising technology allowing to produce large scale porous implant materials.
