The British Orthodontic Society MOrth Cases Prize 2014

Abstract

This paper describes the orthodontic treatment of two cases that were successful in winning the British Orthodontic Society (BOS) Membership in Orthodonitcs (MOrth) cases prize in 2014. The first case describes the management of a 26-year-old female with a Class II division 2 incisor relationship on a Class III skeletal base with reduced vertical proportions. This was complicated by: an unerupted ectopic palatally displaced upper right permanent canine, an erupted palatally displaced upper left permanent canine, retained deciduous canines, generalised microdontia, an overall Bolton tooth size discrepancy, mild crowding in the upper arch, an increased overbite (complete to tooth tissue) and crossbites. Treatment involved a surgical exposure of the ectopic canine and the use of fixed pre-adjusted edgewise appliances over a period of 24 months. The second case describes the management of a 12-year-old female with a Class II division 2 incisor relationship on a Class 2 skeletal base with reduced vertical proportions. This was complicated by: an increased overjet and overbite (complete to soft tissue), mild upper and lower arch crowding and an increased naso-labial angle. Treatment involved an initial phase of modified Clark Twin Block and sectional fixed appliances followed by complete fixed pre-adjusted edgewise appliances over a period of 24 months.
