  "abstract": "Background/objectives\n\nEfficient en-masse retraction of the maxillary anterior teeth requires adequate anchorage control while maintaining acceptable incisor torque. This prospective clinical case series aimed to provide an initial clinical evaluation of a novel laser-welded bi-dimensional archwire designed for miniscrew-supported en-masse retraction in adult patients with Class II Division 1 malocclusion.Methods\n\nSix patients requiring extraction of the maxillary first premolars were treated using a custom-made stainless-steel archwire consisting of a 0.019 × 0.025-inch anterior segment and 0.016 × 0.022-inch posterior segments. Retraction was performed using nickel-titanium closed-coil springs delivering approximately 250 g of force per side. The primary outcome was the monthly rate of maxillary anterior retraction measured on three-dimensional digital models. The secondary outcome was the change in maxillary incisor torque assessed on lateral cephalometric radiographs using the bracket-archwire angle.Results\n\nRepeated measurements showed no statistically significant systematic error, with method errors ranging from 0.14 to 0.31 mm for linear variables and from 0.72° to 1.08° for angular variables; intraclass correlation coefficients ranged from 0.91 to 0.97. The overall mean retraction rate was 0.97 ± 0.05 mm/month, and the mean retraction duration was 5.78 ± 0.79 months. The mean change in maxillary incisor torque was 7.08 ± 1.29°.Conclusions\n\nWithin the limitations of this six-participant clinical case series, the novel bi-dimensional archwire was associated with a relatively stable observed rate of anterior retraction, although a measurable change in the bracket-archwire angular relationship remained. These descriptive findings should be regarded as preliminary and hypothesis-generating and require confirmation in adequately powered controlled studies.Trial registration\n\nClinicalTrials.gov, NCT07664215; retrospectively registered on 24 June 2026.",
