| Résumé | Bioglass® 45S5 is the most widely investigated bioactive glass. It was recently demonstrated that this glass is better integrated into bone when the structure is porous. The National Research Council Canada has recently developed a process to produce metallic and ceramic foams using a powder metallurgy approach. Preliminary tests showed that Bioglass® foams can be produced with this process. These foams are produced by foaming a powder mixture composed of Bioglass® particles, a binder and a foaming agent. Highly porous Bioglass® foams (64-79% porosity) were successfully synthesized from dry powder blends. The porosity of the resulting foams was open and the pore size was essentially between 175 and 880 μm in diameter, as required for bone ingrowth. During sintering, crystallization took place and Na6Ca 3Si6O18 (primary phase) and Na 2Ca4(PO4)2SiO4 (secondary phase) were observed. The mechanical compressive strength ranged from 1.7 to 5.5 MPa. |
