Objective To evaluate the effect of oral digital technology in oral restoration. Methods From January 2023 to January 2024, 100 patients who underwent oral restoration in the Department of Stomatology, Huiji Hospital Affiliated to Hubei Vocational and Technical College were randomly divided into control group and observation group, with 50 patients in each group. The control group was treated with traditional restoration technology, and the observation group was treated with oral digital technology. The repair effect, oral function recovery and complications were compared between the two groups. Results The adhesive strength, color and shape scores of the restorations in the observation group were higher than those in the control group (P <0.05). The recovery rate of tooth function, masticatory function, language function and occlusal correction in the observation group were higher than those in the control group (P <0.05). The incidence of complications in the observation group was 6.00%, which was lower than 22.00% in the control group (P <0.05). Conclusion The application of oral digital technology in oral restoration is effective, which can improve the adhesion strength and aesthetics of the patients' restorations, improve their oral function, the incidence of complications after repair is low and the safety is good.
