Aluminiumoxidkeramik, ein neues Biomaterial

Abstract: The materials and combinations of materials presently used for joint replacements are not completely satisfactory. Therefore, special types of ceramics have been studied for the application of endoprostheses of the heavy load bearing joints. High purity aluminium oxide ceramics have shown the most promising results. In a comparison between the material properties required for joint endoprostheses and the properties of dense, high purity A120 3 ceramics particular emphasis is placed on the problems of mechanica… Show more

“…Long-term increased wear of the polyethylene socket may, however, limit its life expectan~y.~-~ To cope with the problem of wear, Boutin9Jo has introduced a ceramic/ceramic combination for the socket and the ball head. The same path has been followed by Griss et al, [11][12][13] Mittelmeier,14J5 and Salzer et a1.,I6 striving to achieve a cementless anchorage of the ceramic socket in the acetabulum. Long-time clinical results will have to show whether the extremely rigid ceramic socket does not cause bone restoration in the acetabulum.…”

“…Initially the crystal tips of the microscopically uneven surface are broken. At the end of this material depended process a new type of friction is established which can be attributed to a newly formed surface [6]. It is of significant importance to know that this initial corpuscular wear has also to be expected under body fluid lubrication.…”

“…Die fibrigen Tiere zeigten sehr starke Einschr/inkungen ihres Bewegungsablaufes, von starken Stfitzbeinlahmheiten bis hin zur v611igen K o n t r a k t u r der (Griss 1973;Heimke 1974;Young 1979) und dem V4A-Stahl darin weit fiberlegen. Da uns ftir die Oberarmprothesen kein Keramik zur Verffigung stand, mugte auf Stahlprothesen zurfickgegriffen werden.…”
