Ceramics Biomedical Implants

This article briefly describes the principal ceramic materials and surveys the uses to which they are put in medical and dental applications.

Ceramics biomedical implants.

Bioceramics ceramic products or components employed in medical and dental applications mainly as implants and replacements. 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. Advances in ceramic processing have contributed to increased possibility of modifying the materials for use in biomedicine.

Tin has been suggested as the friction surface in hip prostheses. But modern technology is full of advanced ceramics from silicon solar panels to ceramic superconductors and biomedical implants. Ceramics for biomedical applications is a relatively recent phenomenon. Among these ceramics we can cite silicon carbide titanium nitrides and carbides and boron nitride.

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. The inherent brittleness of ceramics has limited their competition with ductile metals and polymers.
