Because of errors at the brim introduced by using a different instrument to measure proximal regions of the sockets (see "Methods" section), we were not able to characterize the effect of weighting ratio on mean SNAE.
The mean SNAE metric, unlike the MRE and IQR metrics described previously, mischaracterized some of the socket clinical fits (Figure 8).
It is interesting that there are vertical lines within the SNAE plots for most of the sockets (left two panels of Figure 9(a) to (c) and Figure 10(a) and (b)), but these lines did not match regions identified clinically in error.
The finding that clinically detected local socket shape problems matched well with dense closed contours of SNAE (Figure 8, Figure 9(a) to (c), and Figure 10(a) and (b)) provides insight into the nature of clinically relevant shaping problems.
More sockets need to be tested before clinically appropriate threshold values can be recommended for MRE, IQR, SNAE, or other criteria.
Do different technicians within a manufacturing facility generate different MRE, IQR, and SNAE results?
A closed contour of elevated SNAE was associated with clinical need for shape modification at the closed contour.
