2011-4-1 · 1. Introduction. Calcium phosphate cements (CPC) for bone reconstruction have been the subject of intense research since they were proposed by Legeros et al. and Brown and Chow nearly 30 years ago. Their self-setting ability allows them to fulfil various requirements, including being placed in bony defects as a mouldable paste that sets and hardens in situ.
