However, recipient beds prepared following apically positioned flap surgery are often trapezoidal in shape, whereas palatal grafts are typically rectangular. This geometric mismatch may require graft trimming, reducing usable donor tissue for recipient\u2010site coverage. The skirt\u2010shaped free gingival graft (S\u2010FGG) technique was developed to improve adaptation between the graft and recipient bed. By improving graft\u2010recipient conformity while preserving graft continuity, the technique may increase the effective utilization of donor tissue and extend the coverage achievable from a given graft harvest.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Two patients with insufficient peri\u2010implant KM at mandibular posterior implant sites were treated using the S\u2010FGG technique.

In Case 1, the postoperative buccal KM width (KMW) measured 6\u00a0mm at definitive prosthesis delivery and remained clinically stable during the subsequent 6\u2010month follow\u2010up. In Case 2, the buccal KMW measured approximately 4\u00a0mm at 4 weeks and stabilized at approximately 3\u00a0mm after tissue maturation. No major postoperative complications were observed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The S\u2010FGG technique appears to be a feasible modification of conventional FGG for peri\u2010implant KM augmentation.
