Objective To explore the application effect of attached gingiva reconstruction in oral implant restoration treatment and its effect on dental function and aesthetic satisfaction. Methods A total of 60 patients who received oral implant restoration treatment in our hospital from January 2021 to May 2022 were selected as the research subjects, and they were divided into conventional group and experimental group by the random number table method, with 30 patients in each group. The conventional group was treated with traditional dental filling, and the experimental group was treated with attached gingiva reconstruction. The dental function, aesthetic restoration effect and aesthetic satisfaction were compared between the two groups. Results The tooth contact time, the percentage of left and right lateral force and the force centre distance in the experimental group were better than those in the conventional group (P <0.05). The scores of restoration colour, restoration shape, overall aesthetics and facial condition in the experimental group were higher than those in the conventional group (P <0.05). The aesthetic satisfaction in the experimental group was 96.67%, which was higher than 83.33% in the conventional group (P <0.05). Conclusion The effect of attached gingiva reconstruction in oral implant restoration treatment is better, which can effectively improve patients’ dental function and restoration appearance, meanwhile, patients’ aesthetic satisfaction is higher, and it is worthy of clinical application.
