-
N = 5 scans for each scanner and model type
- The same symbol after SD indicates differences in precision between scanner pairs (Tukey adjustment for multiple comparison). Minimum signicant difference across scanners: 7.2 μm and 51.2 μm for partially and fully edentulous maxilla models, respectively
-
1
p-value testing of the interaction between scanner and model type (partially vs fully edentulous maxilla) from t-tests taking into account the heterogeneity of variances (Satterthwaite method). A p-value > 0.05 indicates no difference in scanner precision according to model type
