Objective To investigate the effect of CAD/CAM zirconia all-ceramic crown restoration on aesthetic effect and functional recovery of patients with aesthetic restoration of anterior teeth. Methods A total of 60 patients with aesthetic restoration of anterior teeth admitted to our hospital from October 2023 to October 2024 were selected, and they were divided into the observation group (30 patients) and the control group (30 patients) by the random number table method. The control group received traditional metal porcelain crown restoration, and the observation group received CAD/CAM zirconia allceramic crown restoration. The aesthetic effect, functional recovery and complications were compared between the two groups. Results The aesthetic scores of the observation group at 1 and 6 months after surgery were higher than those of the control group, and the masticatory efficiency at 1, 3, and 6 months after surgery was higher than that of the control group (P <0.05). At 6 months after surgery, the aesthetic satisfaction rate of the observation group was 96.67% and the recovery rate of masticatory function was 90.00%, which were higher than those of the control group (83.33%, 83.33%) (P <0.05). The incidence of gingivitis, gingival bleeding and prosthesis loosening in the observation group were lower than those in the control group (P <0.05). Conclusion Compared with traditional metal porcelain crown restoration, CAD/CAM zirconia allceramic crown restoration in aesthetic restoration of anterior teeth is more conducive to improving aesthetic effect, functional recovery and gingival health, and reducing the incidence of complications.
