Objective To explore the application and aesthetic effect of ultra-thin veneer in aesthetic restoration of anterior teeth. Methods From October 2020 to September 2021, 60 patients who received aesthetic restoration of anterior teeth in our hospital were selected as the research objects. They were divided into observation group and control group by random number table method, with 30 cases in each group. The control group was treated with traditional porcelain veneer repair, and the observation group was treated with ultra-thin all-ceramic veneer repair. The repair and complications of the two groups were compared. Results One year after repair, there was no significant difference in the number of patients with USPHS reaching A between the two groups (P>0.05). The incidence of complications in the observation group was 3.33%, which was lower than 26.67% in the control group, and the difference was statistically significant (P
