Methodological diagram of the three-dimensional digital model measurement method. A: Occlusal representation of the segmentation of a maxillary model to identify the areas of a closed scan surface belonging to a dental crown. B: Reference points are assigned to the three-dimensional dental crowns, which form an individual coordinate system and are used in the following diagnostic modules. The reference points are checked in all 3 planes. C: The digital model analysis is then carried out with determination of tooth widths, crown height, overjet/overbite, midline shifts, arch dimensions (anterior and posterior arch width, arch length, arch circumference)
