Correct answer: B — Moyers prediction table (using mandibular incisor widths)
The Moyers mixed dentition analysis uses the sum of mandibular permanent incisor widths to predict the combined mesiodistal widths of unerupted permanent canines and premolars in both arches. Probability tables (typically using the 75th percentile for a conservative estimate) provide predicted values based on the incisor measurements. This analysis helps determine whether adequate space exists in the arch for the permanent successors or whether intervention (space maintenance, serial extraction, arch expansion) is needed.
