      ab: Highlights: What are the main findings? Early orthodontic intervention significantly improves skeletal development, arch dimensions, and airway space in patients with Class II malocclusion. Statistically significant differences favor early treatment in parameters such as gonial angle, maxillary width, and dental arch length. What are the implications of the main finding? Timely application of growth-modifying appliances enhances treatment outcomes and may reduce the need for extractions or prolonged fixed appliance therapy. Individualized treatment timing, particularly favoring early intervention in selected cases, should be integrated into evidence-based planning for orthodontic treatment in pediatric patients. Background/Objectives: The optimal timing for orthodontic treatment in pediatric patients with malocclusion, particularly Class II discrepancies, remains a topic of ongoing clinical debate. Early treatment during the mixed dentition stage harnesses craniofacial growth potential, whereas later intervention may capitalize on pubertal growth for greater skeletal correction, especially for skeletal and airway improvements. This systematic review aimed to compare the outcomes of early versus late orthodontic treatment to assess their relative effectiveness. Methods: A systematic review was conducted in accordance with PRISMA guidelines, including randomized controlled trials and observational studies published between 2015 and 2025. Eleven studies comparing early and late treatment were analyzed, and the risk of bias was evaluated using standardized assessment tools. Results: Of the eleven studies, eight reported statistically significant improvements favoring early orthodontic intervention. Early treatment was associated with greater enhancement of maxillary and mandibular arch development, improved jaw relationships, and expanded airway dimensions. Studies utilizing headgear or other growth-modifying appliances also showed more favorable eruption patterns and alignment, underscoring the clinical relevance of early-phase management. Conclusions: Early orthodontic treatment can provide meaningful benefits in guiding skeletal growth, improving dental arch form, and enhancing treatment efficiency. These benefits were most consistently supported in skeletal and airway outcome domains. While late treatment may be suitable for some cases, personalized planning remains essential. Further large-scale, standardized longitudinal studies are needed to refine treatment-timing protocols in pediatric orthodontics.
