The present invention discloses a medical implant made from calcium phosphate cement, and in particular to a method of preparing a molded and hardened calcium phosphate cement article having a superior compressive strength for use as medical implant. The molded and hardened calcium phosphate cement article may be in the forms of a dense block, a porous block for use as tissue- engineered scaffold, or a dual function block comprising a dense cortical portion bearing the majority of load and a porous cancellous portion allowing a rapid blood/body fluid penetration and tissue ingrowth.
L'invention porte sur un procédé de préparation d'implants médicaux de ciment de phosphate de calcium, et en particulier sur un procédé de préparation d'articles de ciment de phosphate de calcium t moulés et durcis présentant une résistance élevée à la pression et pouvant servir d'implants médicaux. Lesdits articles peuvent être des blocs pleins, ou des blocs poreux constituant des structures de tissus reconstitués, ou des blocs hybrides comprenant une partie corticale dense supportant la majeure partie de la charge, et une partie poreuse spongieuse permettant une imprégnation rapide des fluides corporels et du sang et la croissance intérieure de tissus.
