biocerámicos

Bioceramics are inorganic, non-metallic solids used in medical applications. They are typically composed of highly crystalline oxide ceramics, such as alumina, zirconia, and hydroxyapatite. Bioceramics are chosen for their biocompatibility, meaning they do not elicit an adverse response from the body when implanted. Their inertness prevents them from degrading or reacting with surrounding tissues.

There are several types of bioceramics based on their interaction with the body. Inert bioceramics, like alumina and zirconia, remain largely unchanged after implantation and are used for load-bearing applications such as joint replacements. Bioactive bioceramics, such as some calcium phosphates, can form a bond with living bone tissue. This is due to their ability to stimulate bone growth and integrate with the host bone. Resorbable bioceramics, like certain forms of hydroxyapatite and tricalcium phosphate, are designed to degrade over time and be replaced by new bone tissue. This makes them suitable for bone void fillers and scaffolds for tissue regeneration.

The manufacturing process of bioceramics involves powder processing, shaping, and sintering at high temperatures. These processes are critical for controlling the material's microstructure, density, and mechanical properties. Bioceramics find applications in a wide range of medical devices, including dental implants, bone grafts, orthopedic implants, and coatings for metallic prostheses. Their unique properties continue to drive research and development for advanced biomaterials.
