Vol. 13 – Number 50 – 2020 Case report Page 59-66 Surgical-orthodontic treatment of anterior open bite – case report Mohamad Nagi Bou Wadi¹ Daniel Salvatore de Freitas² Melissa Faccini¹ Karina Maria Salvatore Freitas¹ Fabrício Pinelli Valarelli¹ Abstract Anterior open bite is part of vertical malocclusions and is defined as the presence of a negative overbite between the incisal edges of the maxillary and mandibular anterior teeth, resulting in greater aesthetic and functional impairment. It is a malocclusion that is difficult to treat and of doubtful stability. Its etiology is multifactorial and occurs for two main reasons which are heredity or environmental causes. Anterior open bite is classified into two categories: dental and skeletal. In cases in which there is greater involvement of skeletal components, it is necessary to associate orthognathic surgery with orthodontic treatment. This article aims to detail the treatment of skeletal anterior open bite of a patient treated with orthodontics associated with orthognathic surgery involving only the mandible, with its counterclockwise rotation. The results showed that after orthodontic preparation and orthognathic surgery, the patient presented a Class I molar and canine relationship, improved profile, decreased vertical pattern and passive lip sealing. The correct diagnosis is essential to choose the treatment that generates good results and patient satisfaction, always considering malocclusion severity.
