Abstract
The invention relates to a device for selecting an area () of a dental restoration body (), which is depicted in a 3D representation. At least portions of the area limit are provided in the form of dental-specific lines (). 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 (), which is to be machined with a construction tool, can be determined by selecting dental-specific lines () or dental-specific points () or a preparation edge (). 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 ().
