Randomized trial reveals reduced recession depth for both tunnel technique and free gingival graft in mandibular recessions, suggesting distinct benefits for tissue gain versus healing.
Both techniques were effective in treating multiple mandibular gingival recessions, resulting in a significant reduction in recession depth after 12 months. Free gingival graft showed a more predictable approach for keratinized tissue gain. In contrast, the tunnel technique was superior in healing outcomes.
