3D Digital Assessment of Soft Tissue Changes After Modified FGG

The aim of this randomized controlled clinical trial is to evaluate the effects of conventional free gingival graft (FGG) and modified free gingival graft (ModFGG) techniques on soft tissue thickness, volumetric change, and creeping attachment in mandibular incisors using three-dimensional direct digital analysis. The study will include a total of 34 systemically healthy, non-smoking individuals with localized Cairo Class II gingival recession. Participants will be randomly assigned to the FGG (control) and ModFGG (test) groups. Clinical measurements will be performed before surgery and at 1, 3, and 6 months post-surgery. Soft tissue thickness and volumetric changes will be analyzed three-dimensionally by overlaying digital models obtained with an intraoral scanner. Gingival recession depth, keratinized tissue height, and creeping attachment will also be assessed. The aim is to provide clinical evidence regarding the effects of the modified free gingival graft technique on soft tissue stability and volumetric gains.
