Endosseous implant to be applied to a human or animal bone, wherein the surface of the implant is made from titanium or a titanium alloy, said implant having a smooth or rough surface texture, which is characterized in that said surface has been treated with at least one selected organic phosphonate compound or a pharmaceutically acceptable salt or ester or an amide thereof; process for producing said implants.

Endosseous implant

The present invention relates to modified surfaces. The surfaces comprise an inorganic material on which a phosphinic acid derivative is adsorbed. The phosphinic acid thus turns out to be a new anchoring group useful for surface derivatization. The invention has many applications for photoelectric conversion devices, batteries, capacitors, electrochromic displays, chemical sensors, biological sensors, light emitting diodes, electrodes, semiconductors, separation membranes, selective adsorbents, adsorbents for HPLC, catalysts, implants, nanoparticles, antiadhesives, and anticorrosion coatings, for example.

Modified surface

Endosseous implant to be applied to human or animal bone, said implant having a surface made from a selected metal or a selected metal alloy or a ceramic, whereby said metal resp. metal alloy is selected from chromium, niobium, tantalum, vanadium, zirconium, aluminium, cobalt, nickel, stainless steels or an alloy thereof, said surface having a smooth or rough texture, characterized in that said surface has been treated with at least one pharmaceutically acceptable organic compound carrying at least one phosphonic acid group or a derivative thereof preferably a pharmaceutically acceptable salt or ester or amid thereof and method for producing said implant.
