Biomedical Engineering

 

One of the commonest mechanical interventions in the body is that of the replacement of diseased
mineralised tissue with biomaterials. Filling, capping and replacement of teeth is an obvious
example; other examples include the more invasive procedures that involve replacing the joint of
the hip, the knee, the elbow or the finger, or those of bone reinforcement with plates and pins.
Secondary consequences of the intervention are reduced if the mechanical and thermal properties
of the biomaterial match those of the natural one.
Write a detailed report discussing how closely biomaterials are able to match the properties of bone
and tooth in properties such as modulus and thermal expansion coefficient, and possible
implications of the match.
