Objective: To explore the early dental interventional strategies for adolescent patients and a child patient with cleidocranial dysplasia (CCD). Methods: Surgical exposure using the apically repositioned flap technique combined with orthodontic traction was used in the adolescent patients whose ideal treatment time for initiating treatment was missed. For the child patient whose ideal treatment time for initiating treatment was not missed, the simple surgical exposure method was carried out in order to promote the eruption of the impacted incisors. Results: All the impacted maxillary incisors of the three CCD patients were successfully positioned into a proper alignment either through the two stages of crown exposure and the elastic traction or simple surgical exposure. Conclusion: Crown exposure surgery combined with light force orthodontic traction provides an effective approach to treat the typical dental abnormalities of adolescent CCD patients. Simple surgical exposure was also an effective way for a child CCD patient for whom the most ideal time for initiation of treatment was not missed.
