This study was performed to evaluate the effect on the formation of keratinized attached gingiva when free gingival graft with strip technique was used. After the partial thickness flap was prepared, it was positioned apically more than 7mm using mucoperiosteal suture. At the donor site, strip was achieved with 2mm width, less than 1mm thickness, (mesiodistal teeth length + 6)*2 mm length. Then, it was divided into 2 same pieces and located at the recipient bed apico-coronally with more or less 3mm interval. Follow-up check was made at 1,2,4,8,12 weeks after the operation.
