A titanium implant having increased retention after insertion in bone. The implant comprises phosphate groups bound to the metallic titanium. A process for preparing said titanium implant, wherein an implant is prepared in a per se known manner, and then the oxide layer formed on the surface of the implant, is removed to expose the metallic titanium. The exposed implant is then treated with a phosphate solution in the absence of oxygen, to bond phosphate groups to the titanium surface, said groups securing a firm attachment of the implant to the bone into which it is inserted.
L'invention concerne un implant en titane ayant une rétention augmentée après son introduction dans un os. L'implant comporte des groupes phosphate liés au titane métallique. L'invention concerne un procédé pour préparer ledit implant en titane, dans lequel un implant est préparé de façon connue en soi, puis la couche d'oxyde formée sur la surface de l'implant est retirée pour exposer le titane métallique. L'implant exposé est ensuite traité par une solution de phosphate en l'absence d'oxygène, pour lier les groupes phosphate à la surface du titane, lesdits groupes assurant une fixation solide de l'implant à l'os dans lequel il est introduit.
