Objective To explore the application value of attached gingiva reconstruction surgery in oral implant restoration. Methods A total of 78 patients who underwent oral implant restoration and were admitted to the Department of Implantology, Chongwen Stomatological Hospital in Dongcheng District from January to December 2023 were selected as the research subjects. According to the random number table method, they were divided into the control group and the observation group, with 39 patients in each group. The control group received conventional gingival suture, and the observation group received attached gingiva reconstruction surgery. The clinical efficacy, restoration effect, oral health level, quality of life, inflammatory factor levels and adverse reactions were compared between the two groups. Results The total clinical effective rate in the observation group (97.44%) was higher than that in the control group (79.49%) (P <0.05). The scores of each aspect of restoration effect in the observation group were higher than those in the control group, and the scores of oral health degree and quality of life in the observation group after operation were better than those in the control group (P <0.05). After operation, the levels of TNF-α, IL-6 and IL-8 in the observation group were lower than those in the control group (P <0.05). The incidence of adverse reactions in the observation group was lower than that in the control group (P <0.05). Conclusion In oral implant restoration, the application of attached gingiva reconstruction surgery can improve the restoration effect of patients, enhance the oral health status, inhibit the levels of inflammatory factors, reduce the incidence of adverse reactions, and further improve the quality of life of patients.
