Objective To analyze the application effect of oral digital photography and diagnostic model in patients with aesthetic restoration of anterior teeth. Methods A total of 50 patients undergoing oral restoration in Xingyi People's Hospital from October 2020 to August 2024 were selected and divided into reference group (25 patients) and study group (25 patients) by the random number table method. The reference group was given conventional aesthetic restoration of anterior teeth, and the study group was given oral digital photography combined with diagnostic model technology to assist the treatment. The restoration effect, PES score, aesthetic restoration satisfaction, function recovery and adverse reactions were compared between the two groups. Results The scores of restoration color, restoration form and marginal closeness in the study group were higher than those in the reference group (P <0.05). After restoration, the scores of all dimensions of PES in the two groups were higher than those before restoration, and the scores of all dimensions of PES in the study group were higher than those in the reference group (P <0.05). The satisfaction scores of all items of aesthetic restoration in the study group were higher than those in the reference group (P <0.05). The scores of masticatory efficiency and sound articulation in the study group were higher than those in the reference group (P <0.05). The incidence of adverse reactions in the study group was lower than that in the reference group (P <0.05). Conclusion During the aesthetic restoration of anterior teeth, oral digital photography combined with diagnostic model technology can enhance the restoration effect and aesthetic satisfaction, improve the oral function, and reduce the incidence of adverse reactions.
