Abstract

The frenum is a mucosal fold that attaches the lips or cheeks to the alveolar mucosa, gingiva, and underlying periosteum. Consequences of an abnormal frenal attachment include gingival recession, decreased vestibular depth, decreased range of lip movement, and involvement of interdental papilla, causing a diastema. Several methods to eliminate ectopic frenal attachments have been suggested, including frenectomy (elimination) and frenotomy (repositioning). This case report describes the use of a modified frenectomy technique in a 15-year-old girl with excess gingiva between the maxillary central incisors, which exhibited a 3-mm diastema. First, a semilunar primary incision was made in the palatal surface at a 5-mm distance from the tip of the papilla. Next, sulcular incisions were made around the tooth, and the papilla was transposed to the buccal via a papilla preservation flap. After complete elimination of frenal attachments in the bone, the flap was repositioned and sutured to the palatal surface. Afterward, the frenum was classically cut and sutured. Through this approach, the position of the frenum was changed apically without invading the papilla. At the 3-month follow-up, it was found that the modified technique (combination of papilla preservation flap and frenotomy) had minimized the surgical scar on the buccal surface, preserved the papilla, and yielded optimal esthetic results. © Copyright 2018 by the Academy of General Dentistry.
