Fig. 4From: Accuracy of different tooth surfaces on 3D printed dental models: orthodontic perspectivePercentages of points beyond the upper and lower limits of different tooth surfaces. A 0.10-mm threshold parameter was set as the critical value for analyzing deviations between the plastic and the 3D-printed models. The occlusal surfaces of posterior teeth showed significantly higher percentages of points beyond the upper and lower limitsBack to article page
