Patients were classified as children (8-11 years; n = 120; group 1), adolescents (12-17 years; n = 120; group 2), and young adults (18-25 years; n = 120; group 3).

Therapeutic Protocol for Orthosurgical Management of Class III Malocclusion in Patients With Cleidocranial Dysostosis.

Cleidocranial dysostosis (CCD) is a congenital skeletal disorder with significant manifestations in facial and dental development. Patients are affected with CCD present maxillary deficiency, late dental eruption, and supernumerary teeth. Early and multidisciplinary approach is necessary to treat CCD patients, especially to manage dental eruption and Class III malocclusion with maxillary deficiency.
