    Abstract: The invention relates to a device for selecting an area (2; 22; 32; 42; 52; 62; 72; 82) of a dental restoration body (1;71), which is depicted in a 3D representation. At least portions of the area limit are provided in the form of dental-specific lines (5, 6, 8). The aim of the invention is to carry out a dental construction of a restoration body with the aid of a CAD system, whereby certain areas of the restoration body can be selected and construction tools are provided for machining the selected area in a 3D representation. To this end, the area (2; 22; 32; 42; 52; 62; 72; 82), which is to be machined with a construction tool, can be determined by selecting dental-specific lines (5, 6, 8) or dental-specific points (7.1 7.4) or a preparation edge (4). The method is used for assigning area limits to the selected area, said area limits being provided, at least in part, in the form of dental-specific lines (5, 6, 8).
