    Abstract: A method for producing, on the surface of manufactured articles made of metal, such as for example dental and orthopedic prostheses, a macrostructure and a microstructure, wherein the macrostructure is capable of facilitating the mechanical coupling of the implant and the regrowth of mature trabecular bone structures and the microstructure is capable of facilitating the engagement, at the chemical and physical level, of the surface of the implant by stimulating the osteoinductive/osteoconductive processes of bone tissue. The method comprises the steps of: applying a mask to a metal article; selectively removing part of the mask by means of a computerized system and a laser; applying an electrochemical cycle to remove the exposed material of the article. The electrochemical cycle provides for the application of an electrochemical scanning cycle, which allows to identify the correct working potential and then the application of an electrochemical cycle at constant potential in the work area identified by means of the preceding cycle; removing the remaining mask; generating chemically or electrochemically a micro-rough and/or microporous surface.
