Ceramics Used In Medical Applications
The history of biomaterials can be represented by the use of metallic implants.
Ceramics used in medical applications. Engineering ceramics are used to fabricate components for applications in many industrial sectors including ceramic substrates for electronic devices fig. Ceramic materials are used in a wide range of applications from power distribution to smartphones. 3 turbocharger rotors fig. The need for tough strong and stable bioinert ceramics 2 1 1.
Other examples of medical uses for bioceramics are in pacemakers kidney dialysis machines and respirators. Here we describe their current clinical use and propose a picture of their evolutions for the next 20 years. Clinical use of alternative zirconia based ceramics and composites. 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. 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. 4 and tappet heads for use in automotive engines. Discover the world s research.
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. Ceramics used for this type of applications are called functional ceramics. Ceramics are now commonly used in the medical fields as dental and bone implants. 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.
Manufacturers fabricate numerous ceramic medical appliances from the oxides alumina and zirconia. Biomaterials may be defined as those engineered materials used specifically for medical applications. The nearly 4 5 trillion global electronics industry would not exist without ceramics. Surgical cermets are used regularly.
Biomaterials share with all other engineering materials the classification into the traditional categories of metals ceramics polymers and composites. Ceramic based components are indispensable in products such as smartphones computers televisions automotive electronics and medical devices. 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. Other examples of where advanced ceramics are used include oil free bearings in food processing equipment.
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.
