A process for producing a superstructure (5) for dental prostheses, the process comprising the previous creation of a preformed interface (6) and the subsequent construction, by the stratification of a material (11) on the same interface (6), of the anatomical part (2) of said superstructure (5). With respect to known production methods, the process of the invention offers the advantage of allowing a finished superstructure, i.e. complete with an interface whose geometry has the maximum precision required for an effective coupling with the implant, to be obtained directly in the stratification phase.
