Cleidocranial dysplasia (CCD) is a rare autosomal dominant condition that affects ossification. The dental abnormalities associated with CCD present an obstacle to orthodontic treatment planning. Early diagnosis is crucial to provide the patient with different treatment modalities that will suit the particular patient. In the present case, combined surgical and orthodontic treatment were performed to guide multiple impacted teeth. A single nucleotide missense variation was identified in exon 3 of runt-related transcription factor 2 (RUNX2) in this patient. The current results suggest a correlation between dental alterations and mutations in the runt domain of RUNX2 in CCD patients. Further clinical and genetic studies may required to confirm the association between phenotypes and genotypes in CCD and to identify other factors that may influence the clinical features of this disease. Patients with cleidocranial dysplasia require a team approach which demands good communication and cooperation from the patient. Timing of the intervention is critical, and numerous surgeries may be required. The patient in the present case report was treated by a team of practitioners, which involved several dental specialties to achieve an optimal result.
