Background/Objectives: Class II malocclusion treatment in patients at the end of skeletal growth represents a significant clinical challenge. Traditional sequential distalization with clear aligners often requires prolonged treatment duration, carrying the risk of patient compliance burnout. This article describes a clinical technique combining a “Distalizing Bar Appliance” (DBA) with active lower clear aligners and Class II elastics for the management of dentoalveolar Class II malocclusion, and illustrates its application through a case series of three end-of-growth adolescent patients. Methods: Proposed inclusion criteria and a standardized three-phase workflow are presented: (1) distalization using a DBA supported by Class II elastics, with active lower clear aligners providing anchorage and concurrent crowding resolution; (2) alignment and arch coordination with clear aligners; and (3) finishing for occlusal settling. Results: In all three cases, a Class I molar and canine relationship was achieved, with cephalometric changes consistent with the dentoalveolar mechanisms previously reported for similar appliances and no clinically apparent mandibular skeletal changes. The concurrent use of active lower aligners allowed early crowding resolution, although careful monitoring of lower incisor and molar inclination was required to limit unwanted mesial tipping induced by Class II elastics. Conclusions: Within the limits of a case series, the technique appears clinically feasible and reproducible in carefully selected patients; comparative, controlled studies are needed before any claim of superior efficiency or effectiveness over established Class II treatment modalities can be made.
