The HAnano Surface is a crystalline, 20 nanometer thin and uniform layer of hydroxyapatite (HA). Hydroxyapatite, Ca5(PO4)3OH, is the main constituent of hard structures in the body, such as bone and teeth. All commercial implants, regardless of material and structure, can be coated with the HAnano Surface - creating a highly improved osteoconductive interface between human tissue and implant.
Compared to more conventional coatings, such as micrometer thick, plasma sprayed HA layers, the HAnano Surface is nanometer thin. The thin layer results in that HAnano Surface, illustrated in the top figure, can preserve the micron-structure/micro-roughness of the implant surface while improving the osteoconductivity.
The unique and effective coating procedure is based on a wet chemical process creating a homogenous coverage of HA, even on highly complex implant geometries.The procedure is simple, cost-effective and offers improved osseointegration compared with existing methods.
The surface can be applied in three different ways; through spraying (a), dripping (b) or dipping (c). Excess coating solution is removed by spinning and pressurized gas followed by a short heat treatment
