Abstract

|
The impaction of the maxillary permanent incisor is a common clinical problem and is mostly found at the "labial to the alveolar process." Surgical exposure and orthodontic treatment with fixed orthodontic appliances can be considered if normal eruption of the labillay impacted tooth is not expected. Surgical exposure of the impacted tooth, that is usually under the attached gingiva or is surrounded by alveolar bone through gingivectomy and removal of alveolar bone, may give a rise to complications such as diminution in the width of the attached gingiva, inflammation of the gingiva, and the loss of marginal alveolar bone. Therefore, closed eruption technique, which includes surgical exposure and orthodontic treatment with fixed orthodontic appliances followed by repositioning of surgical flap, is preferred. However, apically repositioned flap of the impacted tooth, which is beneath the movable submucosal area or is above the alveolar crestal area, can prevent unwanted exposures and facilitate successful tooth eruption. In this report, we described esthetic results of three patients with unerupted maxillary permanent incisor who were performed with an apically positioned flap without the loss of attached gingiva.
