Ceramics 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.

Ceramics biomedical implants.

Bioceramics ceramic products or components employed in medical and dental applications mainly as implants and replacements. 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. Tin has been suggested as the friction surface in hip prostheses. The inherent brittleness of ceramics has limited their competition with ductile metals and polymers.

But modern technology is full of advanced ceramics from silicon solar panels to ceramic superconductors and biomedical implants. Among these ceramics we can cite silicon carbide titanium nitrides and carbides and boron nitride. Advances in ceramic processing have contributed to increased possibility of modifying the materials for use in biomedicine. 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.

However they manage to find their way into different implantable systems because of their properties and their good biocompatibility. A number of implanted ceramics have not actually been designed for specific biomedical applications.
