Orthodontic alignment of permanent incisors following previous trauma of a primary tooth.

The primary aims of orthodontic treatment in the mixed dentition are to correct dental arch discrepancies, occlusal and jaw relation abnormalities, and to eliminate functional inteferences—in essence, preventive or interceptive orthodontics. Pediatric dentists should be trained and able to assist their patients if needed. Sequelae to trauma to primary incisors includes: defects in texture, malposition, or delayed eruption of the permanent successors. This case report illustrates correction of rotated and ectopically erupting permanent incisors due to a discolored, over-retained, post-trauma primary central incisor.
