Surgical Management of Aberrant Labial Frenum Using Modified Z-Frenuloplasty: A Case Report.

Frenum is a mucous membrane fold that attaches lips and cheek to the alveolar mucosa, gingiva, and the underlying periosteum. The maxillary frenum can contribute to esthetic problems and can compromise the orthodontic outcome in cases of midline diastema, thus leading to treatment relapse. In addition to this, it may jeopardize the health of the gingival, when it is attached too tightly to the gingival margin, by interference in the plaque control or owing to the muscle pull. These situations can be managed with the help of frenectomy. The presenting case report demonstrates the frenectomy of an anomalous labial frenum in a 20-year-old male using modified Z-frenuloplasty technique.
