Efficacy of Temporary Fixed Retention Following Comprehensive Orthodontic Treatment
… years after treatment). The mandibular Incisor Irregularity index at recall averaged 1.9 mm in the fixed group and 2.5 mm in the Hawley-only group. This ½-mm difference is marginally significant statistically (P = 0.03), but seems trivially small clinically. A 1.0 mm change in Incisor …
