[Upper central incisors and asymmetry: a significant orthodontic             challenge].
In any assessment of the esthetic characteristics of a smile the central incisors play a           decisive role. Moreover, correction of their malpositions and, especially, their           asymmetry, is one of the principal reasons patients consult orthodontists. The etiology of           this asymmetry may be vertical, with one incisor more erupted than its mate or horizontal,           with a mid-line discrepancy, and can be objectified by a clinical examination and           supplementary studies, especially radiological as a means of helping orthodontists adopt           the most appropriate treatment plan. In accordance with the etiopathogenesis of the           malocclusion, alveolo-dental trauma, skeletal asymmetry, or asymmetry of arches, the           orthodontic treatment may be undertaken on three levels, with the teeth themselves by           extrusion, intrusion, or rotation; regionally with the arches by retraction of teeth             en masse; or globally at the skeletal level with maxillo-facial           surgery. The complexity of some treatment in relation to the coordination of different           levels of therapeutic action is intensified by the occasional necessity of obtaining           collaboration of other specialists like general dentists, periodontists, and           maxillo-facial surgeons. In such cases the initial treatment plan takes on increased           importance, as does the choice of collaborating colleagues. However, once successfully           completed these complicated treatments become a source of great satisfaction both for           practitioners and for patients because of the enormous improvement that has been obtained.
