Three-Dimensional Digital Evaluation of Soft Tissue Changes After Modified and Conventional Free Gingival Graft Surgery: A Randomized Controlled Trial

What this Trial Is About

Researchers are evaluating the effects of two types of free gingival graft surgeries—conventional free gingival graft (FGG) and modified free gingival graft (ModFGG)—on soft tissue thickness, volume, and creeping attachment in the lower front teeth. This trial involves 34 healthy, non-smoking adults with localized Cairo Class II gingival recession. The goal is to understand how the modified technique may improve soft tissue stability and volume compared to the conventional method, using advanced three-dimensional digital analysis. Participants will be randomly assigned to receive either the conventional FGG procedure or the modified ModFGG procedure. The ModFGG involves creating a connective tissue flap from the recession area to cover the exposed root before placing a graft from the palate, aiming to enhance blood supply and healing. The conventional FGG involves placing a graft from the palate directly onto the prepared site without this flap. Both procedures will be followed by digital and clinical assessments at baseline, and at 1, 3, and 6 months after surgery. During the study, participants will undergo clinical measurements including gingival recession depth, keratinized tissue width, and probing depth, alongside three-dimensional digital scans with an intraoral scanner to evaluate soft tissue thickness and volume changes. These evaluations at multiple time points will help assess tissue stability and healing progress. The study will last at least six months post-surgery, providing detailed information on soft tissue outcomes and healing after these grafting procedures.
