Luxation Test of Different Ceramic on Ceramic Couplings
Alumina and zirconia have been used for hip joint prostheses for decades. With mixtures of both materials (ZTA and ATZ) mechanical strength can be increased. The resistance against damaging of the surface of the ceramic articulation partners head and liner was investigated using a special luxation apparatus (PI-3:1997-07, Endolab GmbH, Thansau, Germany). Both new ceramic materials ZTA and ATZ showed a better resistance against roughening and damaging of the stressed surface areas during the luxation test compared to alumina.
