Objective To analyze the effect of CAD/CAM digital design in aesthetic restoration of anterior teeth. Methods A total of 62 patients who received aesthetic restoration of anterior teeth in our hospital from January 2023 to December 2024 were selected as the research subjects, and they were divided into the control group and the observation group according to different treatment methods, with 31 patients in each group. The control group received aesthetic restoration of anterior teeth with traditional impression technique, and the observation group received aesthetic restoration of anterior teeth with CAD/CAM digital design. The restoration effect, dental aesthetics and satisfaction were compared between the two groups. Results The total effective rate of restoration in the observation group (96.77%) was higher than that in the control group (80.65%) (P <0.05). The scores of appearance, color, alignment and gingival health in the observation group after restoration were higher than those in the control group (P<0.05). The satisfaction rate of the observation group (93.55%) was higher than that of the control group (77.42%) (P<0.05). Conclusion The application effect of CAD/CAM digital design in aesthetic restoration of anterior teeth is better than that of traditional impression technique. It can achieve better dental aesthetics after restoration and help to improve patient satisfaction.
