Aim of this investigation was to establish and evaluate an AnnexinV/Propidiumiodid cytocompatibility assay for biomaterials, which allows for differentiation of periimplant apoptosis and necrosis. After establishment of the test protocol, the flow cytometric assay was evaluated with different antiinfectious titania surface coatings for medical implants. No significant differences in cytocompatibility were observed between control samples (TiAl6V4) and pure TiO2-coatings; however, increasing amounts of antibacterial copper ions in the coatings resulted in a continuous decrease in cytocompatibility, which could be sensitively detected by the newly applied cytocompatibility assay.
