Fig. 6From: Digital setup accuracy for moderate crowding correction with fixed orthodontic appliances: a prospective studyColor-coded distance maps showing the differences in the palatal reference area, following the superimposition of the maxillary PDM and FDM on the same area (shown model: PDM, reference model: FDM). Most of the cases showed morphological stability, whereas a few cases (patient 4, 7–9, 12 19) presented slight variations (within 0.5 mm), indicating a flattening of the palate in the FDMBack to article page
