Elaboración de un cemento óseo de fosfato de calcio con una adición de biovidrio

Bone cement is synthesized using CaCO3 and CaHPO4, in a thermal treatment at 1400 °C. The mixture was rapidly cooled with a stream of forced air; bone cement was mixed with 10%wt. Bioglass (BC-10BG) later milled and characterized milled and characterized by Particle Size Distribution (PSD), X-ray diffraction and fluorescence (XRD and XRF). The mixing (Bone cement-Bioglass) and bone cement alone were characterized physic- mechamically through testing compressive strength, microhardness, cohesive and setting times; in order to see precipitation trends were carried out in-vitro tests. Additionally, two compositions more of bioglass (5 and 15% wt.) were evaluated by XRD, SEM and FTIR-ATR.The crystalline phases of α-TCP y β-TCP, Ca2P2O7 y CaHPO4 were related to bone cement and whitlockita phase was in agreement with bioglass in one part of its crystalline structure. Physically handling times and the mechanical properties correspond to bone cement for filling cavities. The in-vitro tests showed a progressive bioactive effect with increase the exposition time.
