Fig. 2From: Accuracy of different tooth surfaces on 3D printed dental models: orthodontic perspectiveThe color map shows the differences in different tooth surfaces between the STL reference model and the STL test model. Each tooth surface was individually superimposed on the reference model. a Buccal surfaces of posterior teeth (BP). b Lingual surfaces of posterior teeth (LP). c Occlusal surfaces of posterior teeth (OP). d Buccal surfaces of anterior teeth (BA). e Lingual surfaces of anterior teeth (LA). f Occlusal surfaces of anterior teeth (OA). The darker the color, the larger the variation; the lighter the color, the smaller the variation. Red and blue showed greater deviations than yellow and greenBack to article page
