432 - Clear Aligners for a Patient with CATCH 22 Syndrome

Abstract: CATCH 22 syndrome is one of the common chromosomal disorders resulting from a microdeletion in the q11 region of the chromosome 22, among the total 23 pairs of chromosomes. Depending on clinical symptoms, it is classified as DiGeorge syndrome, conotruncal anomaly face syndrome, and velocardiofacial syndrome. Patients have various clinical symptoms in multiple organs of the body, including dental characteristics such as abnormalities in tooth shape, eruption, number, as well as enamel defects like hypomineralization and hypoplasia. Dental occlusion affects the function and aesthetics, significantly impacting quality of life. However, patient cooperation is crucial for orthodontic treatment. This report presents orthodontic treatment using clear aligners in a 10-year-old child diagnosed with CATCH 22 syndrome. Clear aligners can be attempted effectively in patients with low cooperation levels and can yield satisfactory results for both clinicians and patients. It could be adequate treatment option for patients with disabilities or those facing difficulties in cooperation.
