Orthodontically induced eruption of maxillary central incisors.

      Аннотация: Often the dilacerations are related to a history of trauma in primary teeth. Dilaceration can occur in any region along the length of the tooth and the clinical appearance of this deformity depends on the stage of development at which the injury occurred. The upper central incisors are the most frequently injured teeth, both in primary and permanent dentition. Affected teeth generally do not erupt spontaneously and for the evaluation data from cone beam computed tomography can be required, it is possible to determine the relationship of the impacted tooth with the adjacent teeth and structures. The movement of an impacted tooth towards its place in the dental arch requires orthodontic-surgical treatment. Orthodontic traction can be performed through the use of removable or fixed appliances, to apply light and constant forces. Although several reports indicate that an impacted tooth can be brought into proper alignment in the dental arch, many orthodontists hesitate to align an impacted incisor with severe dilaceration, as there are chances of failure. It is extremely important that orthodontists and clinicians have knowledge about this subject for clinical practice.
