چکیده
Material and Methods: Twenty Five patients including 13 females, 12 males with the mean age of 10.66 years (range, +0.7, -0.8 years) with skeletal Cl III malocclusion due to maxillary deficiency were selected in this study. All of the patients were treated by using a maxillary protraction (Tongue Appliance) as the only treatment appliance. Lateral cephalograms were taken before and after treatment. Data were analyzed statistically by means of paired T-test.
