Biomaterials – Applications in Dental Surgery
From WikiLectures
Definition[edit | edit source]
Any material put into/interact with living organism with the objective to restore, augment or replace the function of the organism. Biomaterials do not have to be biomimetic, but to restore function.

Classification according to bio-compatibility.[edit | edit source]
- Bio-tolerated = no rejection but fibrotic border
- Bio-inert = osteointigration at bone implant contact. Eg Titanium coated with zirconium oxide
- Bio-active = induce changes in body.
- Biotoxic = not used.
