This case involved a 25-year-old male who presented with mild crowding and relapse following previous fixed orthodontic treatment. A non-extraction ClearPath aligner plan was developed, including 13 upper and 19 lower stages, worn 22 hours daily and changed every 10 days. Treatment incorporated interproximal reduction and targeted canine extrusion attachments to improve tooth control. The patient demonstrated excellent compliance, and after 7 months, the relapse was fully corrected with well-aligned arches, ideal overjet and overbite, balanced lip competence, and a stable functional occlusion. Periodontal health remained intact throughout, confirming clear aligners as a predictable, minimally invasive option for orthodontic retreatment.
