Abstract: A composition and method for producing interconnective macroporous, resorbable and injectable calcium phosphate-based cements (MICPCs). The composition of the invention sets to poorly crystalline apatitic calcium phosphate after mixing a powder component and an aqueous solution. The multiphasic calcium phosphate components in the cement resorb at different rates allowing the timely replacement by new bone. The interconnected macroporosity in the cement allows for vascularization, entrapment of growth factors, cell colonization and tissue ingrowth. This MICPC can be used for dental and medical applications relating to bone repair, augmentation, reconstruction, regeneration, and osteoporosis treatment, and also for drug delivery, and as scaffolds for tissue engineering.
