Cleidocranial dysostosis (CCD) is characterized by delayed exfoliation of deciduous teeth, delayed eruption of permanent teeth, and multiple supernumerary teeth. Therefore, many CCD cases need orthodontic treatment. This report describes the long-term treatment of a CCD patient with anterior open bite. The patient was first examined at the age of 10 years. We extracted some deciduous and supernumerary teeth in the anterior maxillary region. However, the patient stopped treatment, then returned for treatment at the age of 17 years, whereupon preoperative orthodontic treatment was begun. We extracted the remaining deciduous teeth and started traction of the impacted permanent teeth. We then performed an anterior alveolar osteotomy of the upper and lower jaws at the patient's age of 24 years. One year postoperatively, the patient has stable occlusion and satisfactory results.
