Alumina ceramic Modern (third generation) alumina ceramic is composed

of very small crystals of aluminium oxide

Page 4: Oxinium

Zirconia toughened alumina (ZTA) ceramic ZTA ceramic is combinations in microseparation

simulator studies consistently showed lower wear than the alumina used as historical control

Zirconica ceramic Is one of the highest-strengh ceramics suitable for

medical use

OxiniumCreate a thin layer of zirconium oxide on the surface of the

solid zirconium metal

Ceramic for total kneesUse for total knee joints is hampered by two facts :

The total knee joints have not congruent joint surfaces

The femoral component that would sustain the stresses that occur during walking in the knee
