Fig. 2From: Comparison of two intraoral scanners based on three-dimensional surface analysisDiscrepancies in the three-dimensional direction were calculated in the incisor and molar regions. Three reference points were selected, and the point-to-point distance between each point on the intraoral scan and the corresponding model scan was computed. The point-to-point distance was regarded as the displacement of the intraoral scan to the model scan, and the relative distance was calculatedBack to article page
