摘要：
The present invention describes a dental implant unit comprising titanium, wherein the dental implant unit has at least one surface (end) for connection and a lateral surface covering all of the implant unit but the connecting end and wherein the lateral surface comprises a layer of synthetically created titanium dioxide and wherein at least the end for connection is free from synthetically created titanium dioxide. Furthermore, the present invention is related to both full-body implants, such as screws, abutments, implant parts, bridges or crowns, and smaller implant bodies, such as particles, grains or granules. In the latter case, the present invention is directed to a whitened implantable dental unit, said dental unit comprising titanium in the form of a titanium metal or titanium alloy, and/or in the form of titanium oxide, said dental unit having a surface comprising synthetically created titanium dioxide and which surface also comprises fluoride bound to the surface. Moreover, the present invention is also related to a method for the production of a whitened implantable dental unit, said method comprising thermal oxidation of a dental implant unit comprising titanium and being solid or porous in the presence of fluoride ions, for the production of a whitened implantable dental unit having a surface comprising synthetically created titanium dioxide.La présente invention concerne une unité d'implant dentaire comprenant du titane, l'unité d'implant dentaire comportant au moins une surface (extrémité) destinée à la liaison et une surface latérale recouvrant l'ensemble de l'unité d'implant à l'exception de l'extrémité de liaison, la surface latérale comprenant une couche de dioxyde de titane créé de manière synthétique et au moins l'extrémité destinée à la liaison étant exempte de dioxyde de titane créé de manière synthétique. La présente invention concerne à la fois des implants de corps complet, tels qu'à vis, de butée, des pièces d'implants, des bridges ou des
