Ceramics Used In Medical Applications

Ceramic based components are indispensable in products such as smartphones computers televisions automotive electronics and medical devices.

Ceramics used in medical applications. The history of biomaterials can be represented by the use of metallic implants. Ceramic materials have been produced for custom practices for centuries but they are a rather modern development in medical processes and applications used in surgical implants prosthetics and various medical tools and devices medical ceramics change lives. 4 and tappet heads for use in automotive engines. Orthopedic procedures that involve the surgical installment of these implants are aimed at replacing hip knee joint cranio maxillofacial and spinal hard tissues and are becoming very.

Joint replacements are commonly coated with bioceramic materials to reduce wear and inflammatory response. The aim of this perspective is to present an overview of the different types of ceramics available for medical applications focused mainly on bioactive glasses. Other examples of medical uses for bioceramics are in pacemakers kidney dialysis machines and respirators. Ceramic materials are used in a wide range of applications from power distribution to smartphones.

Biomaterials share with all other engineering materials the classification into the traditional categories of metals ceramics polymers and composites. Ceramics are now commonly used in the medical fields as dental and bone implants. Biomaterials may be defined as those engineered materials used specifically for medical applications. Discover the world s research.

Engineering ceramics are used to fabricate components for applications in many industrial sectors including ceramic substrates for electronic devices fig. Ceramics for the human body are called bioceramics. Ceramics used for this type of applications are called functional ceramics. Clinical use of alternative zirconia based ceramics and composites.

Surgical cermets are used regularly. 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. High tech ceramics have always been associated to medical devices. The need for tough strong and stable bioinert ceramics 2 1 1.

Yttria stabilised zirconia was the ceramic gold standard in terms of strength and toughness see table 1 but its lack of long term stability is a major issue for medical use. Here we describe their current clinical use and propose a picture of their evolutions for the next 20 years. Manufacturers fabricate numerous ceramic medical appliances from the oxides alumina and zirconia. In electronic and electrical industries advanced ceramic materials like barium titanate batio3 piezoelectric materials and semiconductor materials are heavily used for producing ceramic capacitors vibratos temperature sensors oscillators etc.

Other examples of where advanced ceramics are used include oil free bearings in food processing equipment.
