Vol. 15 – Number 57 – 2022 Case report Page 39-46 Skeletal anterior open bite treatment with extractions of four premolars Rodrigo Hitoshi Higa¹ Fabrício Pinelli Valarelli² Jheny Cecilia Arévalo Castro¹ Michelle Garbulho da Silva Marques³ Roberto Henrique da Costa Grec¹ Abstract Open bite malocclusion in adult individuals is challenging for the orthodontist, who has difficulty for both its closure and the stability of results at the end of treatment, especially when the malocclusion has some skeletal etiology. The following case report presents a seventeen-year-old patient with anterior open bite, molar Angle Class I relationship, severe crowding, marked buccal inclination of incisors and excessive vertical growth pattern. As the patient presented resistance to more invasive interventions, a compensatory treatment was chosen without the association of orthognathic surgery. A protocol with four premolars extractions, associated with intermaxillary elastics in the anterior region was used to achieve a satisfactory closure of this malocclusion. At the end of the treatment, the bite was successfully closed, achieving an esthetic and functional occlusion. It is concluded that even in the presence of a skeletal anterior open bite with great impairment of face harmony, compensatory treatment can be successfully performed, once the orthodontist knows the limitations and treatment techniques.
