The invention is directed to a method for the production of an individual tooth replacement formed of multiple layers, for example, a removable tooth replacement, implant superstructures, bridges, crowns, partial crowns, onlays and inlays. According to the invention, this object is met by a method for producing a tooth replacement formed of multiple layers in that a CAD data set of the tooth replacement to be produced is initially made by digitizing the teeth which are already prepared and their immediate surroundings into which the tooth replacement is to be inserted, in that a first CAD partial data set and a second CAD partial data set are determined from this CAD data set, the first CAD partial data set representing the supporting framework structure of the tooth replacement and the second CAD partial data set representing the aesthetically and/or functionally relevant outer geometry of the tooth replacement which faces predominantly toward the oral cavity, in that the supporting framework structure is then produced by the first CAD partial data set, and the supporting framework structure for the multilayer tooth replacement is then finished using the second CAD partial data set by applying a functional layer, for example, in the form of a ceramic veneer or a polymer facing the mucous membrane.
