Ceramic What is ceramic

ceramic materials used in total joints belong to a class of materials called oxide ceramic

The aluminum oxide appears in three forms :

a. gems

b. surgical grade ceramic

c. pottery

Medical grade ceramic Advantages and risks

Alumina ceramic Modern (third generation) alumina ceramic is composed

of very small crystals of aluminium oxide

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

Oxinium materials for total hips

Oxinium for total knee prosthesis

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

Other ceramic materials Hydroxyapatite coating

Other osteoinductive substances
