Table 2 Comparative differences in the mean value measurements (millimeters) between the articulated master model and the 4 tested groups.
| Parameter (Dimensions) | Master model | AL(C) | AL(E) | AL(F) | 3D-C |
|---|---|---|---|---|---|
| Mean±SD | Mean±SD | Mean±SD | Mean±SD | Mean±SD | |
| Anterior vertical (A1–A2) | 24.660±0.001 | 24.830±0.19 | 24.624±0.19 | 24.721±0.15 | 25.045±0.33 |
| Posterior vertical (P1–P3) | 20.416±0.001 | 20.836±0.15 | 20.648±0.12 | 20.616±0.22 | 20.977±0.26 |
| Anterior-posterior (P1–P4) | 26.711±0.001 | 27.054±0.24 | 26.791±0.24 | 26.976±0.23 | 26.982±0.23 |
| SD – standard deviation; AL(C) – conventional alginate; AL(E) – extended pour alginate; AL(F) – alginate free; 3D-C – three-dimensional printed cast. Significant differences when compared to Master Model at P≤.05 (one sample t-test used). | |||||
