摘要

Suspensions for the preparation of bone grafts (scaffolds) based on biosilicato, bone grafts obtained and process for the production of the same. Suspensions are described based on biosilicato 32 for preparation of bone grafts (scaffolds).The suspensions are compared to the total volume of the suspension, 10 to 50% of solids consisting of 50 to 98% of porogu00eanico agent and 2 to 50% of biosilicato 32 and 50 to 90% of liquids consisting of 0.5 to 15% of a binder and 85 to 99.5% of the liquid medium.In a process for preparing in (110) are mixed binder, a liquid medium and biosilicato 32 forming a suspension, the suspension is ground (120), (130) is added to the agent porogu00eanico in (140) is made of mixture of suspension with the agent porogu00eanico in (150) mixture it is dry in a Powder, (160) powder obtained is sifted in (170) powder is conformed in moulds of any geometry.(180) the product formed is burned and (190) is recovered in the final product scaffold. Bone grafts obtained by this process are the total porosity ranging from 65 to 95%, and the average size of pores between 100 and 600 109 M.
