Extensive Orthodontic Movement in an Adolescent Patient With a Traumatized and Endodontically Treated Maxillary Central Incisor: Case Report With 7 Years of Follow-Up.

This article describes the orthodontic treatment involving a traumatized, endodontically treated upper central incisor that underwent extensive orthodontic movement. A male patient, 13 years and 1 month old, presented with the following conditions: mesofacial, convex profile; Class II skeletal pattern; angle Class I malocclusion; crowding of lower incisors; biprotrusion; and endodontic and restorative treatment of the traumatized left maxillary central incisor. Four first premolars were extracted to reduce dental protrusion and correct crowding of the lower incisors. Low-magnitude forces were applied to the traumatized incisor and the movement time of this tooth was shorter than in the other teeth. Dental alignment and leveling, adequate overjet and overbite, and good positioning of the teeth in their bone bases were obtained. Orthodontic treatment with extensive movement of a traumatized, endodontically treated tooth was performed successfully and showed no root resorption 7.3 years postretention.
