Abstract

Abstract: Objective: To evaluate the clinical effect of apically positioned flap combined with free gingival graft on the reconstruction of implant keratinized gingiva in patients with chronic periodontitis.Methods: Thirty chronic periodontitis patients with insufficient keratinized gingiva around implants were selected and randomly divided into FGG group and control group, with 19 implants in each group. The clinical parameters, including keratinized tissue width (KTW), peri-implant probing depth (PPD), gingival index (GI), modified plaque index (mPI), mucosal recession (MR), and marginal bone loss (MBL) were compared between two groups at baseline, 3 months, and 6 months after treatment.Results: During the period, the implant function of two groups was good, and some measurement indicators (KTW, GI, mPI, GR, MBL) in the FGG group were improved compared with the baseline (P<0.05). After 6 months of follow-up, the conditions of peri-implant tissues (KTW, GI, PI, GR) in the FGG group were significantly improved compared with those in the control group (P<0.05).Conclusion: APF combined with FGG is a practical method to reconstruct the keratinized gingiva of implants in patients with periodontitis. It can maintain the health and stabilize the bone level around the implant in short term.
