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. However they manage to find their way into different implantable systems because of their properties and their good biocompatibility. Among these ceramics we can cite silicon carbide titanium nitrides and carbides and boron nitride. 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.

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. But modern technology is full of advanced ceramics from silicon solar panels to ceramic superconductors and biomedical implants. Tin has been suggested as the friction surface in hip prostheses. Ceramics for biomedical applications is a relatively recent phenomenon.

This article briefly describes the principal ceramic materials and surveys the uses to which they are put in medical and dental applications. An implant is a medical device manufactured to replace a missing biological structure support a damaged biological structure or enhance an existing biological structure.
