Vol. 13 – Number 49 – 2020 Case Report Page 37-50 Longitudinal follow-up of Class II treatment with Herbst appliance – case report Alexandre Moro1 Mayara N. Nakano2 Humberto M. D. Nabarro2 Nathaly D. Morais3 Francielle Topolski4 Gisele Maria Correr4 Abstract Orthodontic treatment has several objectives, one of the most important of which is the stability of the corrections achieved. Longitudinal stability of treatment results is one of the keys to successful orthodontic treatment. Thus, this article is intended to describe a clinical case of a patient with Class II Division 1 malocclusion, treated with the Herbst appliance. In the first phase of treatment, the patient used a Herbst appliance with removable lower acrylic splint. In the second phase, she used a fixed appliance in the upper and lower arches. As a retainer, she used a modified upper Hawley plate and a fixed 3×3 lower retainer. The evaluation 11 years after the end of the treatment allows us to conclude that the Class II treatment with the Herbst appliance in two phases was effective, promoting skeletal, dental and facial changes that were stable.
