Cleidocranial dysplasia (CCD) is a rare congenital condition characterized by patients presenting with craniofacial anomalies, multiple supernumerary and impacted teeth, retained primary teeth, and delayed eruption, necessitating multi-stage and innovative treatment mechanics to facilitate tooth eruption. This case report highlights the orthodontic management of a 21-year-old female with CCD using a sequential, interdisciplinary approach including the extraction of retained primary and supernumerary teeth, and exposure, bonding, and forced eruption of impacted teeth. The latter was achieved with a custom-fabricated lower appliance and a modified transpalatal arch designed to reinforce anchorage and facilitate simultaneous traction of multiple impacted teeth via a closed surgical technique, achieving their successful retrieval and good orthodontic outcomes.
