Color-coded distance maps generated following the superimposition of the mandibular PDM and FDM on the mandibular dental arch (shown model: PDM, reference model: FDM). The lower anterior teeth, premolars, and first molars were accurately positioned in 3, 5, and 5 cases, respectively (error within 0.5 mm). There was no specific pattern in 9, 13, and 4 cases, respectively, where the error was distributed over the dental arch. In half of the cases, the lower anterior teeth had more lingual inclination than the actual outcome. In the PDM, the premolars exhibited more buccal inclination in seven cases and the first molars were more buccally positioned (by approximately 2 mm) in 16 cases
