Abstract

The present invention refers to a type of porous support (or scaffold) made from a biocompatible glass exhibiting in vitro bioactivity that contains calcium phosphate, silica and network modifiers, such as MgO, K2O, Na2O, or B2O3, with the particularity of displaying an exceptional specific surface area and mechanical properties suitable for its use as structures for bone regeneration. The present invention also relates to the processing  of porous architectures where the pores exhibit an exceptionally rough topography, which gives to these supports a high specific surface area, obtained by reactive sintering of glass particles and particles of a salt that acts as porogen.

Innovative aspects & main advantages

The present invention has the following advantages over existing technologies and products:
Low production costs
Materials of high bioactivity and biocompatibility
Porous structures where the pores exhibit an exceptionally wrinkled topography, which bestows them a high specific surface area with potential for application in bone regeneration strategies and/or in drug delivery systems.

Applications

Medical Ceramics.
