Study summary

Objective Peri-implant keratinized mucosa deficiency is a significant factor affecting implant success. Therefore, it is crucial to choose a suitable technique for increasing the width of the keratinized mucosa. This study aims to compare two different approaches of free gingival graft (FGG) application in the treatment of insufficient peri-implant keratinized mucosa and to determine the most effective and predictable technique.

Materials and Methods A total of 38 systemically healthy patients with ≤2 mm of keratinized mucosa in the mandibular anterior region (teeth 33-43) and 38 dental implants were included. Patients were randomly assigned to two groups: Test ( Ring FGG) and Control (Conventional FGG). Clinical parameters including Bleeding on Probing (BOP), Gingival Index (GI), Plaque Index (PI), Probing Depth (PD), Width of Keratinized Mucosa (KMW), Peri-implant Mucosal Thickness (PMT), and Graft Surface Area (GSA) were recorded at baseline, and at 1, 3, and 12 months postoperatively.
