Medical use of ceramics.

The use of ceramics for biomedical applications is a relatively recent phenomenon. Some elements such as carbon or silicon maybe considered ceramics ceramic materials are brittle hard strong in compression and weak in shearing and tension. Ceramics used for the repair and re construction of diseased or damaged parts of the musculo skeletal sys tem termed bioceramics may be bio inert alumina zirconia resorbable tricalcium. Here we describe their current clinical use and propose a picture of their evolutions for the next 20 years.

It is generally stronger. Coshh essentials in ceramics. They are used today as femoral heads and acetabular cups for total hip replacement dental implants and restorations bone fillers and scaffolds for tissue engineering. Surgical cermets are used regularly.

There are a number of other applications that are found in the other areas too. Control of substances hazardous to health in the production of pottery. Valves can now be implanted in patients that are made of ceramic materials. Ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material.

Other examples of medical uses for bioceramics are in pacemakers kidney dialysis machines and respirators. Those made with ceramics last longer than traditional metal hip replacements because the ceramic material is stronger. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. Magnetic ceramics are another type of advanced ceramic material that is used for the production of antennas and inductors.

Hip replacements are now being made with this versatile material. Bioceramics like alumina with high density and purity is used to dental implants. Picking up the pieces. Joint replacements are commonly coated with bioceramic materials to reduce wear and inflammatory response.

There are a variety of medical uses for ceramics. Toughened ceramic is used in hip replacements and is designed to be porous so that it can stimulate natural bone growth around the artificial joint. The ceramic industry health and safety pledge was launched in 2001 in response to the revitalising health and safety strategy. Ceramics are now commonly used in the medical fields as dental and bone implants.

High tech ceramics have always been associated to medical devices. You will also find ceramic fillings for your teeth where the ceramic is chemically bonded to your tooth making it extremely strong. Advances in ceramic processing have contributed to increased possibility of modifying the materials for use in biomedicine. Ceramic compositions and processes zirconia ceramics.

Zirconia ceramic is characterized as an extremely high strength material.
