Influence of the print orientation and cast thickness on the accuracy of DLP master casts for fixed dental prostheses

Table 5 Kruskal-Wallis results for differences between reference points for the external shell thickness, distinguished by X, Y, and Z axes. Statistically significant differences (p-value) among all comparisons are indicated. The group with a value closer to STL0, indicating greater trueness, is also identified
