Cleidocranial Dysplasia (CCD) is a syndrome that causes skeletal growth disturbances. The impaction of many permanent teeth and several supernumerary teeth are among the dental problems of patients with this syndrome. This patient was a 14 y/o girl with CCD syndrome. She was skeletal Cl III with reverse overjet; many impacted teeth, and several supernumerary teeth. Orthodontic treatment was done in two stages. In the first stage, supernumerary anterior teeth were extracted, and the impacted teeth were exposed for traction. In the second stage, posterior supernumerary teeth were removed, and upper canines and posterior impacted teeth were exposed for forced eruption. For traction of the mandibular anterior teeth in the first stage, a new appliance was designed, which included a fixed lower lingual arch, a TMA labial wire, and high-pull headgear with J-hooks. Traction of upper canines and posterior teeth was done with the conventional method using an archwire and other teeth as anchorage. At age 21, orthognathic surgery was performed to correct Class III skeletal relationships. All of the anterior mandibular teeth erupted in a short time with the new appliance. Two premolars and upper canines could erupt into the arch. The patient had no root resorption, no periodontal bone loss, good facial esthetics with Class I skeletal relationship, and normal overjet and overbite. Orthodontics and orthognathic surgery can provide aesthetic and function to CCD patients. The new appliance can be used as an effective device for the traction of multiple impacted teeth in the mandibular anterior area.
