Precision of Fit of Titanium and Cast Implant Frameworks Using a New Matching Formula

Table 1

The best-fit matching results in μm of the cast frameworks to their respective master casts using the fixed method of alignment. 0,0,0 represents the matching centroid position, 𝑥,0,0 and 𝑥,𝑦,0 represent the best fit centroids for that position. The final column is the mean vertical gap at that position centroid.
