Key Concepts & Definitions

  • Biomaterials: Materials designed for use in medical devices or implants that interact with biological systems.
  • Metallic Biomaterials: Metals (e.g., titanium, stainless steel) known for strength, ductility, and corrosion resistance.
  • Ceramic Biomaterials: Inorganic, non-metallic materials (e.g., alumina, zirconia) characterized by hardness, brittleness, and bioactivity.
  • Polymeric Biomaterials: Organic polymers (e.g., PLA, PEG) offering flexibility, biodegradability, and tunable properties.
  • Composite Biomaterials: Combination of two or more material types to optimize properties like strength and bioactivity.
  • Biocompatibility: The ability of a material to perform with an appropriate host response in a specific application.
  • Bioactivity: The ability of a material to elicit a biological response, such as bonding with bone tissue.
  • Biodegradability: The capacity of a material to be broken down by biological processes within the body.
