Bioceramics today
First and second generation bioceramics, that is, almost bioinert, bioactive
and resorbable, are being used today in implants and medical devices. third
generation bioceramics, that is, those driving living tissue regeneration are now
under experimentation and represent hope for the future. a interesting example
of the actual research interests in biomaterials in general and in bioceramics in
particular can be obtained from the programme of the eighth World Biomaterials
Congress that took place in Amsterdam in May-June of 2008. The almost 3000
communications presented were classified into 102 scientific sessions. Twenty
were devoted to tissue engineering or regenerative medicine. the words scaffolds,
cells, stem cells or cellular appeared in the title of 26 sessions. Six sessions were
devoted to surfaces and the prefix 'nano
-
' appeared in another six as a logical
consequence of the interest in nanoscience and nanotechnology. With regards
to the type of material, seven were specifically dedicated to bioceramics, and of
them four to calcium phosphates, one to glasses, one to glass-ceramics and one
to ceramic coatings, and one to dendrimers. in addition, ceramics also appeared
as studied materials in sessions devoted to tissue engineering and regenerative
medicine, bone, porous matrixes, biomaterials for cancer research, injectable
biomaterials, biomechanics, tribology of artificial hip replacements, surface
characterization, composite biomaterials and osteoblast-material interactions.
