Subepithelial gingival connective tissue grafts are a common surgical procedure performed in periodontal and implant surgery. This versatile procedure has many indications including tooth root coverage, thickening of gingiva, and improvement of the quality of the crestal gingiva. Several techniques have been described for graft harvest from the palate. Reported complications from these techniques include pain, inflammation, bleeding, flap necrosis, and infection in the donor site. We report a previously unpublished complication following subepithelial gingival connective tissue graft from the palate: pseudoaneurysm of the greater palatine vessel.
