The present invention relates to a process for the preparation of a topography on a body made of titanium or a titanium alloy. The surface topography allows for improved blood coagulation and/or cell attachment. The process comprises the steps of a) etching at least a portion of the surface of the body with a first etching solution comprising a mineral acid, and then b) etching the surface with a second etching solution different than the first etching solution, said second etching solution comprising hydrofluoric acid. The first etching creates a microscopic topographical formation, and the second etching results in a sub-microscopic formation on the microscopic formation. The first solution may be hydrochloric and sulphuric acid. A macroscopic surface may be provided prior to acid etching using sand blasting. The implant is preferably a dental implant and the surface is in contact with bone or soft tissue. A dental implant obtained by this process, and its use, is also claimed.
