Traditional hydroxyapatite coatings form thick layers on the implant surface, that is easily damaged when the implants are inserted. Compared to traditional coatings, where bone anchors to the coating, HAnano Surface does not act as an interface separating bone from the implant. Since HAnano Surface is particle based there is no risk for cracking or delamination of the coating.
Unmodified and HAnano Surface modified titanium, ceramic, and PEEK implants were evaluated prior to and after implantation into a cortical bone model with Scanning Electron Microscopy. The result showed that the hydroxyapatite crystals still covered the entire implant surface after removal. This shows that HAnano Surface is well-adhered to PEEK, ceramic and titanium surfaces.
