Abstract

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. The results of this study were as follows : 1. The inter-strip space was mostly filled with keratinized attached gingiva. 2. The contraction of the graft was nigligible, and 92% of planned area was filled with keratinized attached gingiva. 3. The inconvenience of the patients at donor site was minimal. 4. The width of the strip was widened. In conclusion, free gingival graft using strip technique is useful to achieve the keratinized attached gingiva maximally with free gingival graft minimally and to minimize the inconvenience of donor palatal site of the patients.
