This paper describes the orthodontic treatment of two cases that were successfully entered for the 2009 MOrth Cases Prize. The first case describes the treatment of a class II division 1 malocclusion with increased vertical proportions that was treated with upper and lower self-ligating appliances and headgear for anchorage support. The second case describes the use of a Clark Twin-Block appliance, with headgear, followed by non-extraction upper and lower fixed appliances to treat a class II division 1 malocclusion with an overjet of 14 mm.
