Abstract:
Objective To investigate the effects of orthodontic treatment of skeletal crossbite adults with mandibular deviation. Methods Eighteen skeletal Class Ⅲ adult patients with borderline skeletal crossbite and mandibular deviation were selected (5 males,13 females). The mean age was 25 years. All cases were treated with straight-wire appliance in upper arch and occlusal plate in the lower arch. Elastics were applied to correct mandibular deviation. Cephalometric analysis was carried out before and after treatment. Paired t-test was performed. Results After treatment, the anterior crossbite was corrected and Class Ⅰ molar and canine relationships were achieved. The inclination of upper incisors was increased significantly. Conclusions Straight-wire appliance combined with occlusal plate was effective on correcting adult patients with mild, moderate skeletal crossbite and mandibular deviation.
