Objective To explore the effect of minimally invasive ultra-thin veneers in young patients with enamel hypoplasia combined with moderate wear and its inffuence on aesthetic effect and functional recovery. Methods A total of 100 young patients with enamel hypoplasia combined with moderate wear treated in Chengdong Branch of Rongdai Dental Clinic from January to December 2024 were selected, and they were divided into the control group (n=50, 255 affected teeth) and the observation group (n=50, 260 affected teeth) by the random number table method. The control group received traditional veneer restoration, and the observation group received minimally invasive ultra-thin veneer restoration. The veneer retention rate, aesthetic effect, functional recovery, tooth preservation degree and postoperative transient sensitivity rate were compared between the two groups. Results The veneer retention rate of both groups was 100.00%, and the difference was not statistically significant (P>0.05). The self-rated VAS satisfaction score of patients in the observation group was higher than that of the control group, and the color difference ΔE value evaluated by physicians was better than that of the control group (P<0.05). The grade A rate of restoration integrity in the two groups was 100.00%, and the difference was not statistically significant (P>0.05). The grade A rate of marginal adaptation in the observation group was higher than that in the control group (P<0.05). The average single-tooth preparation volume, dentin exposure rate and postoperative transient sensitivity rate in the observation group were lower than those in the control group (P<0.05). Conclusion Minimally invasive ultra-thin veneers for young patients with enamel hypoplasia combined with moderate wear can effectively improve aesthetic effect and functional recovery, while maximally protecting tooth tissue and reducing postoperative sensitivity.
