Clinical requirements for calcium phosphate bone cements were formulated in terms of the initial setting time, the final setting time, the cohesion time, and the ultimate compressive strength. Two cement formulations were tested. Biocement F was made of a powder containing alpha-tertiary calcium pho

## Abstract Development of macroporosity during setting would allow fast bone ingrowth and good osteointegration of the implant. The interconnected macropores could be created in calcium phosphate cements (CPCs) through the addition of an effervescent porogen mixture to the component of the cements
## Abstract Synthetic calciumβdeficient apatites (CDA) are structurally similar to biological apatites and are well known as chemical precursors of biphasic calcium phosphates (BCP). BCP are mixtures of hydroxyapatite and Ξ²βtricalcium phosphate and are widely used as bone substitutes in human surge
