Abstract
The invention relates to calcium phosphate composite layers which are electrochemically deposited on bone implants. Implants which are coated in such a way are implanted without cement and are characterised by improved growing-in behaviour. Said highly porous composite layers on implants are made of at least two calcium phosphate phases of different solubility. The highly porous structure of said layers facilitates the immobilisation of cells from which new bone tissue can be made. The different solubility of the individual layer components ensures local concentration of calcium and phosphate ions which accelerates the incorporation process and which adapts to said process over the course of time.
