Polyetheretherketone (PEEK) is a thermoplastic polymer that is appealing for biomedical applications due to its bone-like mechanical properties, chemical stability and radiolucency. However, until now, its hydrophobic nature and inability to integrate directly with bone tissue has inhibited many of its potential applications in the orthopedic sector.
Himed, a USA-based biomaterials manufacturer, has spent years exploring advanced techniques to promote PEEK osseointegration through the use of bioactive calcium phosphate powders and abrasives.
In this white paper, Himed presents three key approaches to overcoming the inert behavior of PEEK, including:
- modifying the surface texture of PEEK with micro abrasives
- applying a bioactive surface coating of hydroxyapatite
- incorporating bioactive materials into PEEK to create a composite material
The vast benefits of PEEK-based implants in hard tissue applications are more readily accessible with these different methodologies for enhancing the polymer’s biocompatibility.
