    Abstract:
    Cleidocranial dysplasia (CCD) is a rare hereditary disorder characterized by skeletal malformations and dental abnormalities. Mutations of the transcription factor RUNX2 are responsible for the pathogenesis of CCD. We present a case of a 10-year-old boy with CCD, presenting with hypoplastic clavicles, delayed closure of the fontanelles, retarded exfoliation of the deciduous teeth, retarded eruption of the permanent teeth, and multiple impacted supernumerary teeth. Based on the clinical and radiographic examination results showing abnormalities of the bones and teeth, a diagnosis was reached easily, but it was difficult to achieve a complete curative effect. We carried out a highly organized schedule of treatment, including extraction of the deciduous and supernumerary teeth, partial resection of alveolar bone, distraction of impacted teeth, and orthodontic surgery. After 7-year follow-up, the patient has achieved acceptable occlusion and midfacial appearance. The main objectives of this study were to present the diagnosis and treatment of CCD and to emphasize the benefits of combined orthodontic-surgical sequential treatment.
