Background: Impaction of maxillary central incisors can result in aesthetic problems. The aim of this retrospective study was to examine the periodontal outcomes of impacted maxillary central incisors after surgical exposure and orthodontic extrusion compared to naturally erupted, contralateral incisors (control).

Results: The …
