Abstract
Methods for enhancing osteoblast functions on a surface of an orthopaedic/dental implant and enhancing osseointegration of an orthopaedic/dental implant consist of providing an orthopaedic/dental implant comprising one or more nanostructured ceramic having a grain size of 1-100 nm or a composite of one or more adhesion-promoting polymers and one or more nanostructured ceramic having a grain size of 1-100 nm, and placing the implant in the body of an animal, where it may be exposed to osteoblast cells. Alumina, titania, or hydroxyapatite is preferred as the nanostructured ceramic.
