What is the ideal material for artificial joint?

The ceramic artificial joint possesses awesome qualities,such as:durability,biochemical inertness,high hardness,good smoothness. it has been improved for its four generations,and becomes more and more perfect.

First generation:the year of 1974-1988,second generation:the year of 1988-1994,third generation:1994-up to now,fourth generation:started clinical applying from 2003. After several generations of developing,the ceramic artificial joint has obtained remarkable achievement.

As the manufacturing process and surgical techniques are developing,the percentage of damage of ceramic artificial joints would be reduced more. on the one hand,people want the ceramic crystal grain smaller but its hardness higher;on the other hand,people are searching new composites and new techniques to low the risk of ceramic breakage.
