Figure 4. Regression of mandibular incisor irregularity by age of untreated subjects. The regression equation was calculated for untreated subjects based on previous studies.9,10 The curve is steeper for subjects 22 years and younger; this segment was used as a norm for the start and end of treatment. A flatter line appeared for subjects 22 years and older; this regression line was used as a norm for recall. — Regression of mandibular incisor irregularity by age of untreated subjects.
