Disclosed is a method for clearing, in particular for removing, unwanted data from optically detected virtual representations of objects, in particular teeth and intraoral structures. The method includes the following steps: a. Defining of an extension line of the representation； b. Stipulating of at least one optimization surface, which in at least one region has a consistent distance to the extension line； c. Securing an inner side and an outer side of the optimization surface； d. Determining of all elements of the representation outside of the outer side of the representation； and e. Removing of all elements outside of the representation.
