Coating solutions using thermal spray technology have been used for various components in biomedical technology. Process variants of plasma spraying are used for processing aluminum oxide, pure titanium, and hydroxyapatite for coating implants. The aim of these coatings is to obtain the best possible connection between the implant and bone tissue. From a medical technology point of view, certain areas of application require the bone tissue to grow more quickly into the implant surface for faster fixation. The injection technology processing of the previously unused material calcium carbonate shows clear advantages in this respect, which could be proven in in-vitro and in-vivo studies. In this paper, calcium carbonate is presented as a novel biomaterial with the aim of accelerated resorption times in comparison to plasma-sprayed plasma-sprayed Hydroxyapatite-coatings as todays standard coating solution on orthopaedic implants. Paper includes a German-language abstract.
