Management of skeletal class II division 2 with deep bite using retro-arch mechanics - case report

Skeletal Class II Division 2 malocclusion with deep bite presents a significant challenge in orthodontic treatment, particularly in non-growing patients. The application of retro-arch mechanics provides a controlled approach for anterior intrusion and deep bite correction while optimizing esthetic and functional outcomes. The aim of this paper was to present a succesfully treated 20-year-old female patient with excessive gingival display, retruded upper incisors, and Class II molar and canine relationships.A non-extraction treatment plan utilizing fixed appliances, sequential archwire progression, and retro-arch mechanics effectively addressed the skeletal and dental discrepancies. This case highlights the efficacy of controlled force application in non-growing patients, contributing to stable and predictable orthodontic outcomes.
Key words: Adult patients, Class II Division 2, Deep bite, Retro-arch mechanics, Orthodontic treatment.
