What are Bioceramic Materials?
They are ceramic materials specifically
designed for use in medicine and dentistry.
They include alumina and zirconia, bioactive
glass, glass ceramics, hydroxyapatite and
resorbable calcium phosphates

Most Bioceramic Materials are Bioactive
A bioactive material is one that elicits a specific
biological response at the interface of the
material which results in the formation of a bond
between the tissues and the
material”
