Esthetic orthodontic management with 3D-printed customized brackets for a Class II malocclusion with severe arch-length discrepancy: A case report

Rationale: Customized lingual appliances fabricated using 3D printing technology offer precise tooth movement and address aesthetic concerns. This case report presents the successful treatment of an adult patient with a Class II malocclusion using this innovative approach. Patient concerns: A 22-year-old female presented with chief concerns about crowding and a desire for discreet orthodontic treatment. Diagnosis: Clinical and radiographic examinations revealed a Class II malocclusion with moderate crowding, increased overjet, and a hyperdivergent facial pattern. Interventions: A comprehensive treatment plan was developed utilizing customized 3D-printed lingual appliances in conjunction with premolar extractions, mini-implant anchorage, and intermaxillary elastics. Outcomes: After 25 months of active treatment, the patient achieved a Class I occlusion with ideal intercuspation, improved facial profile, and resolution of crowding. The treatment outcome remained stable at a 1-year follow-up appointment. Lessons: This case report demonstrates the effectiveness of customized 3D-printed lingual appliances in achieving predictable and efficient orthodontic treatment while addressing patient aesthetic concerns. Advancements in 3D printing technology promise to further enhance the precision, efficiency, and accessibility of this approach in the future.
