Oxide Bioceramic Composites in Orthopedics and Dentistry

Ceramic composites based on alumina and zirconia have found a wide field of application in the present century orthopedic joint replacements, their use dentistry is spreading. The development this class bioceramic was started 1980s, but first clinical applications total hip replacement were introduced market only early 2000s. Since then, several composite systems replacements. These materials are classified as Zirconia-Toughened Alumina if main component or Alumina-Toughened Zirconia when component. In addition, some them may contain third phase strontium exa-aluminate. flexibility device design due to excellent mechanical behavior bioceramics results number innovative devices for replacements hip, knee, shoulder, well dental implants. This paper gives an overview different available made out oxide today under development.
