Biomaterials such as bioceramics have long been used for the regeneration of damaged or degenerated bone tissue. Our focus is on calcium phosphate ceramics such as beta tricalcium phosphate (β-TCP), an excellent degradable bioceramic. β-TCP acts as an osteoconductive material and has the ability to form strong bonds with the host bone. They are used as scaffolds in tissue engineering for bone regeneration, but also as a coating for implants made of titanium and titanium alloys to combine the bioactivity of calcium phosphates with the strength of the metal, or as a porous carrier for the transport of active substances such as antibiotics. We are currently trying to reduce the layer thicknesses on implants (by a factor of 10) in order to prevent the bioceramic coating from shearing off during the implantation of a hip or knee joint prosthesis.
