11.6 Analyses
The analyses are shown when all the necessary measurements are
available. Otherwise they are shown in red.
Bolton
Tooth width measurements are used to obtain the Bolton analysis using the
following formulae:
•
Bolton overall = (sum of mesiodistal widths of 12 mandibular teeth) /
(sum of mesiodistal widths of 12 maxillary teeth) * 100%
•
Bolton anterior = (sum of mesiodistal widths of 6 mandibular teeth) /
(sum of mesiodistal widths of 6 maxillary teeth) * 100%
Space analysis
To obtain tooth width and arch length measurements for space analysis use
the following formulae:
•
Measure arch circumference from mesial of first molar to mesial of first
molar = space available
•
Measure the mesiodistal width of teeth from 5 to 5 and add together =
space required:
•
Reduce the space required from the space available = arch length
discrepancy
NOTE
The first arch length measurement for upper and lower jaw is used in the
calculation of Space analysis.
11.7 Comparison tools
The comparison tools can be used to compare the models from different
time-points.
