89. What is bio ceramics ? Bioceramics are ceramicmaterials specially developed for use as medical and dental implants. They are usually used to replace hard tissue in the body like bone and teeth. Common bioceramics are alumina, zirconia and a form of calcium phosphate known as hydroxyapatite. Bioactive and Bioinert Bioactive ceramics interact with the body so that tissue bonding and eventual incorporation into the body occurs after a time. Calcium phosphate-based bioceramics are bioactive. Bioinert ceramics do not interact with the body's environment apart from causing an initial ‘fibrous tissue’ reaction, which coats the ceramic. Alumina and zirconia-based ceramics are classed as bioinert.

Bioactive and Bioinert

Bioactive ceramics interact with the body so that tissue bonding and eventual incorporation into the body occurs after a time. Calcium phosphate-based bioceramics are bioactive.

Bioinert ceramics do not interact with the body's environment apart from causing an initial ‘fibrous tissue’ reaction, which coats the ceramic. Alumina and zirconia-based ceramics are classed as bioinert.
