Evaluating changes in facial structure during maxillary expansion with a specialized appliance
Hard and Soft Tissue Changes During Maxillary Expansion Using Skeletally Anchored Appliances: a Prospective, Randomized Clinical Study.
This study is testing how a special orthodontic appliance can change the shape of the face in young people aged 12 to 26 during treatment for teeth alignment.

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.
Who should consider this trial
Good fit: Ideal candidates for this study are adolescents and young adults aged 12 to 26 with a maxillary transverse deficit and lateral crossbite.
Not a fit: Patients who have undergone previous orthodontic treatment, have craniofacial anomalies, severe facial asymmetries, are pregnant, or have periodontal lesions may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved orthodontic treatment strategies that enhance facial aesthetics and functional outcomes for patients.
How similar studies have performed: While the use of CAD/CAM technology in orthodontics is gaining traction, this specific approach to evaluating soft and hard tissue changes during maxillary expansion is relatively novel and has not been extensively tested in prior studies.
