About

This study aims to three-dimensionally assess the changes in the airway morphology after anterior segment retraction using maximum anchorage.

Full description

Participants were recruited from the Faculty of Dentistry, Beni-Suef University. All subjects were informed of the treatment procedures and signed a consent form. Methodology: The patients were treated by using fixed appliance and extraction of four first premolars. Maximum anchorage was obtained by using miniscrews that were inserted between the maxillary first molars and second premolars. En masse retraction of the upper and lower anterior segments was carried out by using NiTi closed coil springs. Cone beam computed tomography (CBCT) will be obtained before (T0) and after en masse retraction (T1). CBCT will be used for three-dimensional evaluation of the changes of the airway morphology after en masse retraction of the upper and lower anterior segments with maximum anchorage. The results will be obtained and statistically evaluated.
