Soft-tissue augmentation for increasing keratinized tissue around dental implants: A systematic review

Despite the limitations, this study emphasizes the potential to augment KM width through apically positioned partial-thickness flaps and VP techniques employing XCM or FGG. Further RCTs with extended follow-up are needed to refine treatment approaches, improve outcomes, and address gaps in understanding graft integration mechanisms and strategies to minimize graft shrinkage.
