Study Overview
Brief Summary
Aim of the study: To compare radiographically the morphometric changes in the nasal airway after using three types of rapid maxillary expansion (RME) conventional hyrax (CH), hybrid hyrax (HH) and maxillary skeletal expander (MSE) using cone beam computed tomography (CBCT).
Detailed Description
Abstract Aim of the study: To compare radiographically the morphometric changes in the nasal airway after using three types of rapid maxillary expansion (RME) conventional hyrax (CH), hybrid hyrax (HH) and maxillary skeletal expander (MSE) using cone beam computed tomography (CBCT).
Material and Methods
A total sample of thirty CBCT of patients presented with constricted maxilla with mean age of 14±3Y was randomized in to three groups. Group 1 CH, group 2 HH and group 3 MSE.
CBCT records were taken before(T1) and after six months (T2) of RME; the Airway was segmented and quantified using software (version 5.3.4.39USA).
