Table 2.

Comparative differences in the mean value measurements (millimeters) between the articulated master model and the 4 tested groups.

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).
