The implant surface has since long been recognised as important for the host response to oral implants. When the implant is inserted in the body, blood will immediately cover the implant surface. Different surface properties may trigger proteins and signalling system to enhance and speed up the healing process. The implant surface can be altered with respect to topography, chemistry, physics and mechanical properties. In particular, so far the surface topography and chemistry have gained the greatest interest from researchers and manufacturers of oral implants.
