Transposition: an orthodontist's dilemma-a case report

Tooth transposition presents a major challenge in the correction of a malocclusion. A dental transposition is an uncommon disturbance affecting 0.4% of the population. The treatment difficulties make this anomaly an occurrence of orthodontic interest and a source of clinical interest. The treatment requires a great deal of control and carefully applied mechanics. This case report demonstrates the orthodontic management of the unilateral transposition of a maxillary canine with a premolar and missing bilateral incisors that was treated orthodontically without reversing the transposed tooth positions. The case required combined orthodontic and prosthodontic intervention to achieve acceptable morphologic and esthetic occlusion.
