Abstract: Gingival recession is one of the most important defects that affect oral function and aesthetics. For severe recession with inadequate keratinized gingiva and shallow vestibule, it is difficult to achieve satisfied root coverage with conventional periodontal surgery. In this case report, we utilized laterally positioned flap combined with sub-epithelial connective tissue for this type of recession and got 77.8% root coverage. The width of keratinized gingiva increased to 2 mm after surgery.

Key words: Gingival recession, Laterally positioned flap, Subepithelial connective tissue flap, Root coverage
