The Bionator appliance was applied to Group 1, while the Forsus FRD EZ2 appliance was applied to Group 2. Three-dimensional images were captured before and after functional appliance use in both groups. Dolphin 3D software was used for airway measurements.ResultsNo statistically significant difference was found between the groups in terms of volumetric and area measurements. There was a statistically significant difference between the minimum axial T and O-N border T measurements of the groups.ConclusionThe use of functional appliances may contribute to an increase in oropharyngeal airway dimensions, but there was no difference between the Bionator and Forsus groups in terms of volumetric measurements.en10.1080/08869634.2022.2147283info:eu-repo/semantics/closedAccessOropharyngeal AirwayBionatorForsusMandibular RetrognathiaCone Beam Computed TomographyClass-Ii MalocclusionSkeletal Class-IiBeam Computed-TomographyFunctional AppliancesOrthopedic TreatmentCervical-SpineHead PostureDimensionsTherapyPositionArticle416529541Q4WOS:0008893440000012-s2.0-8514228907536394427Q3
