Ceramic Implants and the Structure of Bone

The requirements for a ceramic implant depend on what its role in the body will be. For example, the requirements for a total hip prosthesis (THP) will be different from those for a middle ear implant. However, there are two basic criteria  

The ceramic should be compatible with the physiological environment. 

Its mechanical properties should match those of the tissue being replaced.
