Although the free gingival graft (FGG) remains the most predictable method for increasing KMW, harvesting large grafts is often limited by palatal donor-site anatomy and associated morbidity. The slit free gingival graft (slit-FGG) is a straightforward modification that enables controlled width expansion without compromising structural continuity, thereby reducing donor tissue requirements. In this technique, a single full-thickness longitudinal incision is made in the harvested graft, creating two juxtaposed ribbons connected by intact lateral platforms. These ribbons can be displaced unidirectionally or bidirectionally to achieve the desired expansion and adapted over an apically positioned mucosa on a prepared periosteal bed. Four systemically healthy patients with insufficient KMW in large edentulous areas were treated using the slit-FGG as part of staged implant therapy. All patients reported minimal postoperative discomfort, and at 6 months the augmented sites demonstrated stable vestibular depth and maintained increases in KMW.

The strip gingival graft (SGG) technique, which involves an apically positioned flap (APF) in combination with an autogenous SGG and a xenogeneic collagen matrix (XCM), has demonstrated its efficacy in reestablishing an adequate amount of KM width at implant sites. Nevertheless, it is still unclear whether harvesting the SGG from the palate (pSGG) or from the buccal aspect (bSGG) of natural dentition affects the esthetic outcome at the augmented implant sites. Therefore, the objective of the present study was to compare the esthetic outcomes of dental implants augmented with either bSGG + XCM or pSGG + XCM. The present study was designed as a single-center retrospective study, assessing the esthetic and colorimetric outcomes of peri-implant KM augmentation with either pSGG + XCM or bSGG + XCM in a cohort of 49 subjects. The two groups were compared in terms of colorimetric outcomes, assessed on clinical photographs using specific software that was able to identify and quantify the predominant color within the peri-implant soft tissue. Colorimetric comparisons with adjacent untreated sites were also investigated. In addition, the Pink Esthetic Score (PES) and a subjective evaluation of the esthetics (SEE) were performed to further assess the esthetic outcomes of pSGG + XCM and bSGG + XCM. The colorimetric analysis did not show statistically significant differences among sites augmented with pSGG + XCM, sites augmented with bSGG + XCM, and untreated sites.
