“…Thirty-three articles were then selected for full-text assessment. After the full-text appraisal, 26 articles were excluded due to the following reasons: Article in a different language [30], sample age below 16 years old [24,[31][32][33][34], Different premolar extractions [35,36], Different anchorage designs [25,[37][38][39][40][41][42][43], Different malocclusion [44], Nonretrospective studies [16,19,22,[45][46][47][48][49][50]. Six eligible retrospective study articles were selected in this systematic review [20,22,23,[51][52][53].…”

Objective: Orthodontic treatment aims not only to treat one's malocclusion and facial aesthetics but also to maintain or improve the patient's airway patency. This review aims to evaluate post-treatment changes in the position of hyoid bone and oropharyngeal airway size and dimensions associated with fixed orthodontic treatment with four first bicuspid extractions in non-growing Class I skeletal bimaxillary protrusion individuals. Methods: Electronic databases including Embase, Web of Science, PubMed, and Scopus were used to research published articles. Included studies assessed the post-treatment effects of four first bicuspid extractions with maximum anchorage on pharyngeal airway dimensions in non-growing patients. Relevant data were obtained, summarised, and analysed from the included studies. © 2020 Terese Winslow LLC, U.S. Govt. has certain rights. OSA is one of the sleep-breathing disturbances caused by collapsing of the upper airway during sleep, characterised by cessation of airflow with persistent respiratory effort, oxygen de-saturations, sleep arousals and sleep fragmentation [4]. Although OSA is a multifactorial disorder associated with obesity, age, facial morphology, airway collapsibility, and neuromuscular feedback, the size of the oropharyngeal airway is highly associated with OSA severity [5-12].Results: Six articles were selected in this systematic review after meeting the requirements of the inclusion criteria. Conclusions: Four bicuspid extractions followed by maximum anchorage involves predominant retraction of the anterior segment of the arches in non-growing skeletal Class I bimaxillary protrusion cases. Extraction of four first premolars led to retraction of the anterior segment and the retroclination of anterior teeth, which narrowed the pharyngeal airway dimensions. After such treatment, the hyoid bone position changes remain inconclusive, which warrants further studies.

Objectives: To evaluate and compare the alterations taking place in the oro-pharyngeal airway space with functional appliance between class I & treated class II division 1 subjects. The st Methods: udy comprised of forty ve participants. Of these, thirty subjects were divided into two groups (Group 1 & 2) who had Angles Class II Division I malocclusion. Subjects with Angles Class I malocclusion formed the control group (Group 3) with 15 subjects. Group 1 received standard twin block therapy and Group 2 received xed functional appliance. The control group received xed mechanotherapy. A full skull CBCT scan was taken pre and post treatment in the two study groups and the control group to check for changes that occurred in the oro-pharyngeal volume. The volume of the oro-pharyngeal airway space was analyzed by student's t test and Tukey's post hoc tests using SPSS Version 22.0. (For Windows) Group 2 and group 3 exhibited a Results: statistically signicant increase in the mean oropharyngeal space volume (p < 0.01) during the post treatment period when compared to the pretreatment. volumes. Increased oro-pharyngeal space was seen in twin block therapy Conclusion: since it brings about both skeletal and dento-alveolar changes while xed functional appliance showed comparatively less changes in the oropharyngeal space.
