Injectable calcium phosphate cements are frequently used for filling of bone defects due to their excellent osteocompatibility. Their poor degradability, however, limits complete regeneration of bone defects. Organic additives that produce acid by-products are particularly attractive to create macroporosity in situ since calcium phosphate cements (CPC) degrade by acid dissolution. ...
