Introduction: There are different treatment modalities for correction of Class II malocclusion. The camouflage treatment is a method of extraction ofpremolars to correct borderline skeletal malocclusion. Utility arches have different roles in various stages of orthodontic treatment. The retrusion utility arch is a useful method in camouflage treatment to obtain intrusion and retrusion of the upper anterior teeth. Aim: The case report documented the treatment of 14-year-old boy with borderline skeletal Class II malocclusion with over jet of 7 mm, 100% deep bite and angle Class II molar, canine, and incisor relationships. Methods: The orthodontic treatment was initiated using 0.022" Pre-adjusted edge-wise appliances (PEA) with extraction of 14 and 24 with maximum anchorage. After the initial leveling and alignment, intrusion and retraction of maxillary anterior teeth were done using 0.016" x 0.022" titanium molybdenum alloy retrusion utility arch. Elastic module tie back was used for upper canine retraction. Finishing and detailing was done after the space closure. Results: The treatment objective of normal over jet and overbite, correction of crowding and achieving Class I canine and incisor relationship were achieved. Conclusion: A stable, harmonious occlusion was achieved after 24 months of PEA treatment along with retrusion utility arch. An upper wrapped around retainer, and lower lingual bonded retainer were issued to retain the stable occlusion.
