Titanium implants are frequently used in dentistry and orthopedics due to their excellent biocompatibility and mechanical properties. The natural oxide layer that forms on the surface of these implants plays a crucial role in their biological performance. Studies have shown that anodization and nanostructuring can improve the bioactivity of titanium surfaces [1]. However, the ceramic rutile structure (TiO2) has a ceramic character due to its ionic and covalent bonds (Ionicity QTiO=59,4 %) and is, therefore, highly brittle. Additively manufactured lattice structures have a significantly higher surface area, which increases the proportion of ceramic rutile compounds.
