Abstract

Bimaxillary protrusion is characterized by protrusive and proclined upper and lower incisors. Since patients with bimaxillary protrusion generally have perfectly good occlusion, orthodontic treatment is often solely sought to correct the protrusive profile and less concern about the airway space change. Typical orthodontic treatment includes extraction of the bimaxillary premolars and anterior tooth retraction, with maximum anchorage. Recently, the relationship between maximum anchorage and tooth displacement is well recognized, retrospective upper airway analysis after retraction of the large incisors remains to be established. This article review previous studies about the pharyngeal airway changes after orthodontic treatment of class I bimaxillary protrusion.
