Abstract
A 16-year-old male adolescent came to our orthodontic clinic with a chief complaint of poor dental alignment. Clinical examination revealed Angle Class II malocclusion with tooth #12 blocked-in and tooth #41 congenital missing. Large anterior overjet and posterior buccal crossbite between #17 and #47 were also noted. Cephalometric analysis indicated a low mandibular plane angle. To acquire a harmonious arch coordination and to relieve anterior crowding, teeth #14 and #24 were extracted. Mechanism involved intermaxillary elastics for a better intercuspal interdigitation, mechanical stress for tooth #12 alignment, and vertical offset to eliminate antagonistic interference for easy correction of scissors bite. The improvement of both facial appearance and dentition alignment was noticeable. Finally, adequate overbite and overjet were achieved.
