Malocclusions with narrow upper arches are usually treated in the mixed dentition with a traditional bonded maxillary expander. Most recently, a new design of a removable expander by Align was brought to our attention. In this prospective clinical study, the investigators will compare the patient-reported treatment outcomes and the dental-skeletal treatment effects on palatal dimensions. With this study, the investigators will have a better understanding of this newly developed appliance and its application in early orthodontic treatment.
