Comparison of Microsurgical and Conventional Techniques for Augmentation of Keratinized Mucosa Around Dental İmplants

Abstract

Objective: This study aims to compare the clinical outcomes of periodontal microsurgery with conventional periodontal surgery in keratinized mucosa augmentation around the implant. Materials and Methods: Ten patients with at least 2 implants with a keratinized mucosal width of < 2 mm were included. Free gingival graft (FGG) was applied in the test group with the microsurgery technique whereas in the control group with the conventional periodontal surgery technique. Keratinized mucosa width (KMW) and palatal mucosal thickness (MT) were measured at baseline and 3rd month. Graft shrinkage(GS) was evaluated at the 3rd month. Donor site wound healing was evaluated at the 10th day and 3rd month. Feedback forms were collected on the 10th day. Results: KMW values increased significantly in both groups at 3rd month compared to baseline. The percentage of GS was lower in the test group at 3rd month, but this difference was not significant. MT values in the test group were closer to the baseline values at 3rd month compared to the control group. Wound healing scores were similar in both groups at the 10th day and 3rd month. Postoperative pain levels decreased more rapidly in the test group. Conclusion: The microsurgical technique provides a faster increase in palatal mucosal thickness and lower graft shrinkage during the healing period and an earlier reduction in postoperative pain levels.
