The requirement of sufficient amount of keratinized attached gingiva to preserve a healthy periodontium is not critical but favorable for most periodontists. Gingival recession, an associated risk factor with an inadequate amount of keratinized gingiva, may cause root surface exposure. The main goals of increasing keratinized attached gingiva and covering exposed root include esthetic improvement, sensitivity release and inflammation reduction for natural and restored dentition. In addition, an increased keratinized attachment may facilitate to prevent further gingival recession consentaneously. In this case report, a modified technique that combined a coronal full thickness flap with an apical split thickness flap was introduced to treat a periodontal defect and increase the keratinized attached gingiva in the same operation. The second wound site correlated with a free gingival graft or a connective tissue graft was therefore avoided and the patients' discomforts were reduced. Acceptable results have been achieved and maintained for more than six months. The advantages and limitations of this adopted technique are discussed. Blood supply and the thickness of gingival and flap tissues may be the important factors influencing the performance and outcome of this modified technique.
