Flap Surgery
A periodontal surgical technique in which gingival tissue is incised and reflected to provide direct access to the root surfaces and underlying alveolar bone for debridement or osseous recontouring.
Full Definition
Periodontal flap surgery encompasses a range of procedures — including the modified Widman flap, apically positioned flap, and undisplaced flap — that share the principle of reflecting soft tissue to gain visibility and instrument access to subgingival structures. The technique allows thorough root debridement, osseous surgery, and regenerative procedures that are impossible through closed (non-surgical) approaches. Editors should note that 'flap surgery' is a general descriptive term, and manuscripts should ideally specify the flap design used. The term is not synonymous with 'osseous surgery,' which may or may not be performed in conjunction with a flap procedure. Capitalisation of named flap types (e.g., 'modified Widman flap') follows the convention of retaining the eponym in title case.
Usage
Usage note: Specify the flap design (e.g., 'modified Widman flap') when the generic term 'flap surgery' is insufficient for the document's purpose. Do not use interchangeably with 'osseous surgery'; the latter specifically involves bone recontouring.

- "The methods section should clarify which flap design was employed rather than using the generic term 'flap surgery.'" — Manuscript editorial comment
