  1. Mean maximum forces (N) ± SD for the three different loading durations 0.1 s, 1.0 s and 10.0 s in the course of the measurement time points T1-T5. Group C represents corrected teeth, whose position was actively modified with the positioner, Group N represents uncorrected teeth adjacent to the ones of Group C, and Group U incorporates uncorrected teeth not adjacent to the ones from Group C
