Frenectomy
Pronunciation: freh-NEK-toh-mee
Surgical removal or repositioning of a frenum — a fold of mucosal tissue — that is causing tension on the gingival margin or contributing to a diastema.
Full Definition
A frenectomy in the periodontal context refers to the excision of a labial or lingual frenum attachment that is exerting pathological pull on the gingival margin, potentially exacerbating recession or impeding plaque control. The procedure is commonly performed at the maxillary midline when a low frenum is associated with a central diastema or at the mandibular lingual frenum when tongue movement is restricted. Editors should note the distinction between frenectomy (complete removal) and frenotomy (incision to release tension without full excision).
Usage
Usage note: Distinguish from frenotomy; the suffix '-ectomy' implies removal, '-otomy' implies incision only.
In Context
