Three-dimensional printing (3DP) and conventional study models were compared. Measurements were generally significantly different regardless of the type of crowding. The mean biases were within ±0.15 mm (SD, <0.40 mm) but were significantly different (P <0.05). The 95% limits of agreement were beyond the acceptable clinical significance set at ±0.50 mm. The 3DP models produced were not clinically acceptable alternatives for linear measurements.
