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

Table 6

The mean and SD of the centroid location differences in μm of each component between test framework and reference cast generated by the unfixed coordinate system best-fit matching method. The right most column presents their total mean and SD (𝑛=6).
