Abstract

Background: This case reports the orthodontic management of a 23-year-old female who presented at the Lagos University Teaching Hospital with Angle's class II division 1 malocclusion on skeletal pattern II. This was complicated by increased overjet of 8.5mm, increased upper and lower incisal angles, mild upper anterior crowding of 2mm, constricted lower anterior arch, Ellis class I fracture of the upper right incisors, rotated teeth 21, 22, and 16, and the upper midline shift to the right by 1mm.

Methods: Interdisciplinary management was done with Oral/Maxillofacial Surgery and restorative units where a 2-unit extraction of the maxillary first premolars and composite restoration of tooth 21 were done respectively. Comprehensive upper and lower fixed orthodontic appliance, preadjusted edgewise was used using Roth 0.022 prescription brackets.

Results: The treatment was completed in 26 months and the outlined objectives were achieved. Conclusion: The objectives for the treatment were achieved and the patient had significant improvement in appearance. Fixed lingual of both arches and Hawley's were used for retention.
