Orthodontic re-treatment case of a class II skeletal base malocclusion: A case report

Orthodontic re-treatment often presents significant challenges for orthodontists due to the complexities involved in addressing the results of previous treatment. A 30-year-old female was re-treated orthodontically to achieve satisfactory results. The clinical examination showed an upper and lower conventional fixed appliance in situ , with an overall poor oral condition and poor orthodontic management of the case. She presented with a Class III incisor relationship on a Class II skeletal base with a convex facial profile due to the severely retroclined upper incisors, proclined lower incisors with reverse overjet. Generalized tooth mobility could be observed with multiple root resorptions, as well as horizontal alveolar bone loss in certain areas. Pre-orthodontic re-treatment preparations were undertaken. Following that, orthodontic treatment utilizing passive self-ligating brackets and extractions was performed to correct the incisor relationship, establish an acceptable functional and esthetic occlusal relationship, as well as better facial appearance, without further compromising the periodontal condition.
