This patient had a congenitally missed upper lateral incisor and the other lateral has an unmoral shape. The goal of the orthodontic treatment for our patient is to open the space for the missed tooth to place a dental implant and to gives the other lateral incisor its appropriate shape after giving it its normal space. Finally that gives our patient a nice smile and a good occlusion. That had been established after only one year of the orthodontic treatment.
