The invention provides a titanium implant having increased retention after insertion in bone. The implant comprises phosphate groups bound to the metallic titanium. Also provided is a process for preparing said titanium implant, wherein the oxide layer formed on the surface of a conventional titanium 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.
