Developments in mesoporous ceramics in drug delivery, nanomedicine, and bone tissue regeneration have opened promising developments in biomedical research, many applicable in the clinic in the near future. Due to the ability to fine-tune the physicochemical properties of these materials, the field has experienced an impressive burst in the number of publications. As controlled drug delivery systems are one of the most promising applications for human health care, it is now necessary to set the milestones of this technology, from the very basic to the most advanced.
