Abstract

Abstract:
 
 Introduction: Class II malocclusion is a common issue that orthodontists must deal with, representing almost one third of all malocclusions. A link between Class II malocclusion and reduced pharyngeal airway dimensions has been reported. This malocclusion has been treated using a variety of methods. Distalization with Carrière Motion appliance is one of these methods. Aim: Evaluation of the effect of distalization with Carrière Motion appliance as a part of orthodontic treatment on airway dimensions. Materials and methods: Eighteen adult Patients aged from 18-30 years with a full set of permanent dentitions were subjected to wear Carrière Motion appliance for about 4 to 6 months. CBCT images were taken before and after distalization for comparison. Results: The results of this study showed a positive effect of Carrière Motion II on increasing the total airway volume. For the total airway volume, there was a significant increase from 39.9 ± 2.7 ml to 44.9 ± 2.6 ml. Conclusion: Total airway volume (upper airway) was increased significantly.
