Abstract
Results: The mean average error in the sample was -0.4 μm. The average upper limit of
95% confidence interval was 36.5 μm, while the average lower limit of 95% confidence
interval was -37.3 μm. The mean RMS of the errors found was 18.9 μm.
Conclusions: Merging digitized definitive impressions to correct marginal defects resulted
in master casts with high level of accuracy relative to the standard reference.
