Ceramic Bearing Surfaces

Why use Ceramics!

The current theory among doctors and authors is that failure of total hip replacements is directly dependent on the amount of wear of the implant. One reason this reltionship exist is because the amount of wear results in loosening of the implant. Ceramics offer a better alternative to traditional materails because they have a smaller wear rate.


One of the drawbacks of ceramics is that their long term results are not yet known. In addition, ceramic hip replacements have demonstrated 'catastrophic failure', similar to traditional ceramic dishes. This is due to the hard and brittle nature of ceramics resulting in the material being crackable. However, with new advanced ceramics this problem has become less of a problem and the chances of catatrophic failure are very small.
