The use of preoperative virtual planning and patient-specific implants allows the bone contour to be as close as possible to the original.
Coordinated solutions are available for computer-assisted planning of surgical procedures, efficient design of individualised treatment concepts and implementing these concepts in the operating theatre using functionalised implants. The resulting benefits for patients include reduced complication rates, improved aesthetic and functional outcomes, shorter operating times and faster rehabilitation. PEEK is a polymer material that could be an alternative to titanium implants in surgical therapy. The reason for this is that PEEK has mechanical properties similar to bone, is very elastic but at the same time very hard and tough, has a low weight, does not cause thermal sensitivity and produces low artefact formation on X-ray images. However, as a bioinert material, PEEK has poor wetting properties and stable tissue and bone integration has not been fully achieved.Inspired by the sponge-like morphology of the biological bone model, the aim is to transfer a porous, easily wettable surface structure to the surface of the PEEK implant.
