Vol. 16 – Number 63 – 2023 Aligners Page 134-142 Correction of deep overbite and Class II subdivision with orthodontic aligners – case report José Augusto Mendes Miguel¹ Arthur Cunha da Silva¹ Flavia Artese¹ Abstract Correcting deep overbite using orthodontic aligners is a challenge for orthodontists. Successful treatment depends on auxiliary mechanics to a better control of the desired movements. The aim of this article was to describe a clinical case of deep overbite correction associated with Class II malocclusion, treated with orthodontic aligners. The patient presented with Class II, division 2, and right subdivision, lower midline deviated to the right, gummy smile, and exaggerated overbite, with crowding in both arches. At the end of treatment, a correct overbite and overjet relationship were achieved, as well as a Class I molar and canine relationship, coincident midlines and an adequate smile arch, maintaining facial symmetry and aesthetics. Considering the limitations of using aligners to correct deep overbite, the case presented satisfactory results, with adequate occlusion, function and aesthetic relationship. The correct treatment plan, aided by orthodontic accessories and the patient’s cooperation, made it possible to correct the overbite and Class II with orthodontic aligners.
