It is a relatively common clinical experience to see a impacted maxillary central incisor Most often, the central incisor is impacted labially. The labial impaction has been indicated as the most difficult to manage. The labial impactions have been found to be associated with mucogingival recession, reduced attached gingiva and periodontal pockets. For the successful treatment, clinicians should avoid loss of attached gingiva in surgical exposure. The most common methods of uncovering labially impacted maxillary anterior teeth are gingivectomy, apically positioned flap and closed eruption technique. If gingivectomy will not leave enough attached gingiva, then an apically positioned flap may be the treatment of choice. If the tooth is impacted in the middle of the alveolus or high in the vestibule near the nasal spine, the closed eruption technique may be the treatment of choice. Closed eruption technique was used in one case, apically positioned flap was used in two case. As the result in two cases of impacted maxillary central incisor, apically positioned flap provide the adequate width of attached gingiva. In case of impacted maxillary central incisor, through the clinical and radiologic examination to select correct surgical operation for reduce the complications.
