Evaluating changes in facial structure during maxillary expansion with a specialized appliance

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial evaluates the effects of maxillary expansion on both hard and soft tissues in the midfacial region using a computer-aided design and manufacturing (CAD/CAM) appliance. Participants, aged 12 to 26, will undergo orthodontic treatment that includes the placement of temporary anchorage devices and a fixed multibracket appliance. The study will utilize advanced imaging techniques such as intraoral scans, face scans, and cone-beam computed tomography (CBCT) to assess changes in the bony structures and soft tissues during the treatment process. The goal is to provide a comprehensive understanding of how this innovative approach impacts orthodontic outcomes.
