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.

The inherent brittleness of ceramics has limited their competition with ductile metals and polymers. Tin has been suggested as the friction surface in hip prostheses. Among these ceramics we can cite silicon carbide titanium nitrides and carbides and boron nitride. Bioceramics ceramic products or components employed in medical and dental applications mainly as implants and replacements.

Advances in ceramic processing have contributed to increased possibility of modifying the materials for use in biomedicine. A number of implanted ceramics have not actually been designed for specific biomedical applications. However they manage to find their way into different implantable systems because of their properties and their good biocompatibility. An implant is a medical device manufactured to replace a missing biological structure support a damaged biological structure or enhance an existing biological structure.

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. 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.
