Table 4.
Equivalence between physical measurements using the MicroScribe CMM and VR measurements using ImmersiveView™ established via two one-sided tests (TOST) with equivalence margins of ± 0.5 mm for linear measurements and ± 0.7° for angular measurements in three objects from both raters combined. p values < 0.05 indicate the null hypotheses were rejected and the equivalence was established
