OBJECTIVES: To compare nickel-titanium (NiTi) wires and clear aligners in the management of mandibular incisor crowding.
METHODS: Seventy-two participants were arbitrarily alienated into two groups with 36 samples in each. Group I participants were treated with NiTi arch wires and group II participants with clear aligners. Malocclusion was evaluated using Little's irregularity index. A questionnaire was applied to record the discomfort levels. Patients were recalled regularly at four weeks, eight weeks, and twelve weeks.
RESULTS: At baseline, the mean score was 2.91 mm and 2.72 mm; at 4 weeks, it was 1.64 mm and1.48 mm; at 8 weeks, it was 0.98 mm and1.0 mm; and at 12 weeks, it was 0.68 mm and 0.52 mm in groups I and II, respectively. The mean change in Little's irregularity index score at 4 weeks was 1.27 mm and 1.24 mm; at 8 weeks, it was 0.66 mm and 0.48 mm; and at 12 weeks, it was 0.30 mm and 0.48 mm in groups I and II, respectively. The disparity was not-considerable (p > 0.05). The mean discomfort score at baseline was 2.8 and 2.5; at 4 weeks, it was 2.4 and 2.0; at 8 weeks, it was 1.8 and 1.4; and at 12 weeks, it was 1.3 and 1.0 for groups I and II correspondingly. The disparity was non-significant (p > 0.05).
CONCLUSION: From the present study, it was found that both NiTi wires and clear aligners were equally effective in managing mandibular anterior crowding cases.
