New implant surfaces continue to attract interest from scientists, manufacturers, as well as from the implant market. New surface modifications are commonly related to variations in nanotopography, chemistry, and/or physical alterations. However, if one factor is altered, inevitably others may change as well - a nanocoat, for example, alters topography, but most likely, chemistry and possibly hydrophilicity will be altered as well. Thus, it is very difficult to know which individual factor will influence the biological response to the greatest extent.
Most surface modifications are still aimed at improving the implant incorporation into the bone, but some articles have been published on surface variations to improve soft tissue adherence and to establish antibacterial coats. Several studies report an improved healing capacity in in vivo experiments, but more studies are required to clarify the clinical relevance of such innovations.
