Objective To analyze the effect of oral digital photography combined with diagnostic model and conventional colorimetry in patients with aesthetic restoration of anterior teeth. Methods From April 2022 to April 2023, 90 patients with anterior teeth loss who underwent aesthetic restoration of anterior teeth in the Department of Stomatology, Yongjian Lihua Dental Clinic, Handan City were selected as the research objects. According to different repair methods, they were divided into control group and observation group, with 45 patients in each group. The control group was given conventional colorimetry, and the observation group was given oral digital photography combined with diagnostic model. The repair effect, aesthetic effect, aesthetic satisfaction and complications were compared between the two groups. Results The scores of aesthetic appearance, color matching, tooth texture and edge adaptability in the observation group were higher than those in the control group at 3 months after repair (P <0.05). The scores of mesial gingival papilla, alveolar process shape, distal gingival papilla, labial gingival margin level, soft tissue color, soft tissue shape and soft tissue texture in the observation group were higher than those in the control group at 3 months after repair (P <0.05). The satisfaction scores of comfort, aesthetics, gingival margin, color, shape and personalized aesthetics in the observation group were higher than those in the control group (P <0.05). The incidence of complications in the observation group was 4.44%, which was lower than 20.00% in the control group (P <0.05). Conclusion Compared with the conventional colorimetric method, the application of oral digital photography combined with diagnostic model in the aesthetic restoration of anterior teeth can effectively improve the repair effect, reduce the occurrence of complications, and improve the aesthetic satisfaction.
