biocompatible nanoceramics otherwise nanostructured bioceramics (rus. нанокерамика, биосовместимая) — nanostructured ceramic material used in medicine to repair (replace) damaged hard tissues.


Nanoceramics are inorganic non-metal materials manufactured by the high temperature sintering of individual particles. The structure of this solid material is formed by contacting grains sized from one to several hundred nanometres.

In medical applications (orthopedics, trauma surgery, oral surgery and dental surgery), the most commonly used types of ceramics are those based on β-tricalcium phosphate Ca3(PO4)2, calcium hydroxyapatite Ca5(PO4)3OH, aluminium oxide Al2O3 and zirconium oxide ZrO2.

Ceramics are mostly biologically inert or biocompatible and have no side effects (such as inflammations or rejection of the implant). For this reason, ceramics are often used to coat implanted materials.

Due to their premium hardness characteristics, ceramics make implants much more wear-proof and help minimize their decomposition, the development of immunogenic microparticles and corrosion.

Hydroxyapatite and various calcium phosphate compounds are exceptions in the ceramics domain in terms of biocompatibility. They are biologically active materials that facilitate interaction between the bone tissue and an implant and expedite bone regeneration processes.
