Abstract

Objective: To investigate efficiency, behavior, and properties of superelastic NiTi vs multistranded stainless steel wires in Begg and preadjusted edgewise appliance (PEA) under moderate to severe crowding conditions. Material and Methods: Ninety-six participants (48 male, 48 female), aged 12-18 years old (mean age = 15.2 ± 1.95), with moderate (≥ 6 mm; mean = 5.3 ± 0.48) to severe (> 6 mm; mean = 7.9 ± 0.66) initial crowding were distributed into four groups: superelastic NiTi PEA (n = 24), superelastic NiTi Begg (n = 24), multistranded (coaxial) stainless steel PEA (n = 25), and multistranded (coaxial) stainless steel Begg (n=23). In this study, 0.16-inch superelastic (austenitic active) NiTi and 0.175-inch multistranded (six stranded, coaxial) stainless steel wires were used in a 0.022-inch slot (Roth prescription) PEA and Begg appliance with a follow-up of six weeks. Results: Analysis of variance revealed no significant difference in reduction of crowding between superelastic NiTi PEA and multistranded (coaxial) stainless steel PEA groups, but reduction in crowding was significantly greater in the superelastic NiTi Begg group compared with the multistranded (coaxial) stainless steel Begg group with F (3, 44) = 8.896, P <.001, and effect size(ω) 0.57 in moderate crowding and F (3, 44) = 122.341, P <.001, and effect size (ω) 0.93 in severe crowding. Linear regression demonstrated significant (P <.05) positive correlation between amount of initial crowding and reduction in crowding in all groups except the multistranded (coaxial) stainless steel Begg group, wherein a negative correlation did exist. Conclusion: Superelastic NiTi performed significantly better than multistranded (coaxial) stainless steel wire in the Begg appliance. However, in PEA, there was no significant difference.
