Ceramic implants offer greater wear resistance and smooth movement of the joint.
Ceramic on ceramic hip replacement no restrictions.
The extreme hardness of this type of ceramic offers greater scratch resistance than the conventional implants used in conventional hip replacements 1 ceramic on ceramic surfaces have demonstrated significantly lower wear versus conventional plastic on metal hip systems in the laboratory 2 therefore it is anticipated that these improved wear characteristics may extend the life of the implant.
Ceramic total hip replacement using a third generation zta ceramic bearing.
This hardness provides ceramic hip replacements with an extremely smooth surface making them much less prone to wear.
Ceramic hip replacement disadvantages.
A ceramic cup can not incorporate the lip that is a standard part of a plastic cup liner.
Therefore a ceramic on poly replacement has the advantage of the lip and a ceramic on ceramic has the advantage of being tougher and permitting the use of a larger femoral head.
This all new ceramic material has the surface hardness and scratch resistance of.
This lip serves to lower the risk of dislocation.
Many surgeons today consider them to be an improvement over traditional metal and plastic implants in which the deterioration of plastic can lead to the gradual buildup of debris around the joint.
It could be a ceramic on ceramic implant or a ceramic on plastic implant.
Ceramic hip replacement involves the use of a relatively newer type of implant which is made up of alumina ceramics.
These are some of the hardest substances known with only diamond being harder than aluminum oxide ceramics.
The ceramics used in hip replacement surgery are alumina ceramic and zirconia ceramic.
