Dentigerous cyst after distraction osteogenesis of the mandible

Damage to the dentition or tooth follicle is often cited as a potential complication of Distraction Osteogenesis (DO). The authors describe a case of a dentigerous cyst that developed following DO of the mandible. The possible histogenic mechanisms and the management are outlined. Understanding the causes of dentigerous cysts as well as the anatomy of the neonatal mandible may help avoid such a complication in the future.
