Background: Respiratory function is highly relevant to orthodontic diagnosis and treatment planning.Skeletal features such as retrusion of mandible may lead to narrower anteroposterior dimension of the airway.

Aims: The present study aimed to evaluate the influence of removable and fixed functional mechanotherapy on the upper and lower pharyngeal airway space in Class II patients during peak pubertal and post pubertal growth spurt.

Materials and Method: A cross- sectional retrospective study was carried out on a total of 20 subjects with age group ranging from 9 -15 years. These patients had ANB angulation greater or equal to 4 degrees and presented with Class II skeletal patterns (mandibular retrusion). They were divided into two groups with subjects receiving removable functional treatment with Twin Block and fixed functional treatment with FORSUS (3M Unitek) over a minimum period of 7-8 months. Pre and Post cephalometric tracings were done to evaluate the changes in both the upper and lower pharyngeal airway space.

Results: Subjects treated with Removable functional mechanotherapy showed a mean change of 15.1% in the upper pharyngeal space while the lower pharyngeal airway space showed a mean change of 25.5% whereas those treated with Fixed functionalmechanotherapy showed a mean change of 15.2% in the upper pharyngeal space and a mean change of 18.39% in the lower pharyngeal space.

Conclusions: Results confirmed that both removable and fixed functional appliances have a significant role in increasing the upper and lower pharyngeal airway spaces in patients with mandibular deficiencies, though removable functional appliances had a greater effect on the lower pharyngeal airway space in contrast to fixed functional appliances.
