Ceramics Biomedical Implants

Among these ceramics we can cite silicon carbide titanium nitrides and carbides and boron nitride.

Ceramics biomedical implants.

Many of those advanced polycrystalline ceramics are combinations of crystalline grains which at the microscopic level resemble a stone fence held together with limestone mortar. But modern technology is full of advanced ceramics from silicon solar panels to ceramic superconductors and biomedical implants. This paper deals mainly with three different types of biomedical implants made of ceramics namely in the areas of hip joint femoral heads orbital implants and bone regenerative dental. Tin has been suggested as the friction surface in hip prostheses.

A number of implanted ceramics have not actually been designed for specific biomedical applications. Ceramics for biomedical applications is a relatively recent phenomenon. Advances in ceramic processing have contributed to increased possibility of modifying the materials for use in biomedicine. Medical implants are man made devices in contrast to a transplant which is a transplanted biomedical tissue the surface of implants that contact the body might be made of a biomedical material such as titanium silicone.

The inherent brittleness of ceramics has limited their competition with ductile metals and polymers. However they manage to find their way into different implantable systems because of their properties and their good biocompatibility.
