Summary: | In the last decade, the development of third generation
bioceramics for Bone Tissue Regeneration has experienced
significant progress with the emergence of a
new generation of nanostructured materials named mesoporous
bioactive glasses (MBG). This new generation of
materials, also known as “templated glasses”, presents
chemical compositions similar to those of conventional
bioactive sol–gel glasses and the added value of an ordered
mesopore arrangement. This article shows an indepth
comparative study of the ordered porous structures
of MBGs compared to conventional glasses (melt and solgel)
andhowthese properties influence the bioactivity process.
Moreover, the possibility to tailor the textural and
structural properties of these nanostructured materials by
an exhaustive control of the different synthesis parameters
is also discussed. A brief overview regarding the possibility
of using these materials as controlled drug delivery
systems and as starting materials for the fabrication of 3D
scaffolds for bone tissue regeneration is also given.
