Ceramics Biomedical Implants

An implant is a medical device manufactured to replace a missing biological structure support a damaged biological structure or enhance an existing biological structure.

Ceramics biomedical implants.

The inherent brittleness of ceramics has limited their competition with ductile metals and polymers. Advances in ceramic processing have contributed to increased possibility of modifying the materials for use in biomedicine. 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. 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. This article briefly describes the principal ceramic materials and surveys the uses to which they are put in medical and dental applications. Among these ceramics we can cite silicon carbide titanium nitrides and carbides and boron nitride. A number of implanted ceramics have not actually been designed for specific biomedical applications.

Tin has been suggested as the friction surface in hip prostheses. Ceramics for biomedical applications is a relatively recent phenomenon.
