Introduction
The authors evaluated the effect of the Carriere motion II appliance on the pharyngeal airway parameters in a sample of class II patients, using cone beam computed tomography (CBCT).

Material and methods
A retrospective sample of 20 adult patients with class II malocclusion who received treatment with Carriere motion II appliance were included in this study. The total airway volume and the minimum cross-sectional area were assessed before and after treatment using Anatomage software on the CBCT scans. Statistical analysis of the collected data was performed.

Results
The measured airway parameters increased significantly after correction of the class II malocclusion using the Carrier motion II appliance.

Conclusions
The use of the Carriere class II motion appliance resulted in an increase the total pharyngeal airway volume as well as in the minimum cross-sectional area after treatment.
