Definitions
- certain metallic ions such as, for example, are used to produce an antimicrobially active coating.
- Other materials that implants with antimicrobial activity can have are, for example, PEEK, PPSU with included additives, such as hydroxyapatite (HA), calcium carbonate (CaCCb), strontium (Sr), ⁇ - or ß-tricalcium phosphate (a- or ß-TCP ), Bioglass particles / particles made of bioactive glass, a polyester material such as PDLLA, PLGA, PLA, PGA, chitosan fibers or chitosan particles.
- a porous implant achieves a better result than a non-porous / solid implant
