Author(s): Alqahtani Nasser*, Rana Alshammari, Thikriat Al-Jewair, Mohammad Aldosari and Albarakati Sahar
Objectives: The goals of orthodontic treatment are not only limited to correcting malocclusion and facial appearance but also extend to achieving normal function of the stomatognathic system and airway patency. This study aimed to investigate postorthodontic pharyngeal airway changes after the extraction of the four first premolars with subsequent retraction of the incisor teeth in patients with bimaxillary protrusion. Materials and methods: Pre- and post-treatment cephalometric radiographs of adult patients (age range 18-30 years) who underwent orthodontic therapy for class I bimaxillary protrusion from April to July 2018 were obtained. Fixed orthodontic therapy following first premolar extraction was the absolute inclusion criteria. Cephalometric measurements of dental (upper and lower incisor retraction and retroclination) and pharyngeal .. Read More»
