Medical zirconia ceramics

Description

Zirconia ceramics made from nanopowders possesses homogeneous structure ensuring high strength and stability against degradation. It is the material possessing significant advantages in life time and biocompatibility over other materials used in medicine as implants and prothesis. Thorough experiments* on human materials (in vitro) and animals (in vivo), have shown the fast bone-implant contact formation with no inflammatory/allergic reaction towards DonIPE zirconia ceramics from nano-sized powders. It is actually many times more beneficial than any other metal material due to it’s chemical inertness. Another matchless advantage of zirconia ceramics is the natural color and aesthetic look of dental prothesis and crowns. Zirconia outstanding biocompatibility, high strength and low wear** (tribological tests - 1000000 cycles) are key fundamentals for hip joint head production.
