METHODS FOR PREPARING MEDICAL IMPLANTS FROM CALCIUM PHOSPHATE CEMENT AND MEDICAL IMPLANTS

摘要

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.
