Summary: The following investigation focuses on polyetheretherketone (PEEK) for bone substitutes intended for maxillofacial surgery. Different three‐dimensional discs with a diameter of 12 mm and a height of 3 mm were laser sintered. As filler materials nano‐sized carbon black and β ‐tricalciumphosphate powder with an average grain size of 35 µm were used. Human osteoblasts were cultivated on the discs and examined with scanning electron microscopy. Cell vitality and cell growth was investigated. The data shows that PEEK surfaces does not suppress osteoblast proliferation.
