Bearing Materials
Some of the newer models of implants are using
metal-on-metal bearing materials. Metal-on-metal tends to have less debris particles than the more traditional metal-on-polyethylene implants. This means that the wear on the
newer devices is much less and the debris particles are smaller. It is thought that the effects of the particles are similar to the metal-on-polyethylene, however, studies are still being conducted on the long-term effects of these materials.

Metal-on Metal with
BFH™ TechnologyThere are also ceramic-on-ceramic devices. The main advantage of ceramic-on-ceramic devices is longevity. There are fewer wear problems, which allows the implant to remain without being replaced for significant portion of the patient\'s lifespan. This advantage may be reduced for older patients.

There are many studies that report wear rates for implant materials. There is no single study that tests all available artificial orthopedic joint materials for wear in the same manner, but from all the articles that are available, it is possible to approximate annual wear rates for these materials. Ceramic-on-ceramic has the lowest wear rate of any material choices. It seems one important contributing factor may be the small quantity of wear debris. The main design aspects of implants that allow such success appear to be the surface finish, diametrical clearance, material, and roundness.
