[Surgical-orthodontic treatment of an impacted maxillary incisor].

An eruption disturbance of a central maxillary incisor can be caused by the intrusion of a deciduous incisor. Depending on the age of the individual when trauma occurred, this may lead to a so-called dilaceration. Surgical exposure and ligation if needed, followed by orthodontic extrusion, will generally be successful. In one case, the central upper incisor appeared to be dislodged and exposure, ligation and orthodontic extrusion resulted in an excellent aesthetic result.
