Abstract
This paper describes the orthodontic treatment of two cases that were successfully entered for the 2005 American Orthodontics MOrth Cases Prize. The first case is that of a patient presenting with a Class II division 2 malocclusion treated with upper and lower fixed appliances plus headgear. The second case demonstrates the use of a twin-block appliance, followed by fixed appliances to correct a moderate Class II division 1 malocclusion.
