Abstract

Abstract: PURPOSE: To compare the aesthetic effects of resin restoration and CAD/CAM all-porcelain veneer restoration on anterior tooth space. METHODS: The medical records of 185 patients (333 teeth) with anterior space restoration from February 2023 to January 2024 were retrospectively analyzed. The patients were divided into control group(n=92, 170 teeth) and experimental group(n=93, 163 teeth) according the restoration methods. The control group was repaired with resin,while the experimental group was repaired with CAD/CAM all-porcelain veneer. The clinical effect, masticatory function, periodontal health status, aesthetic effect and complications were compared between the two groups. SPSS 25.0 software package was used for statistical analysis of the data. RESULTS: The total effective rate of the experimental group was significantly higher than that of the control group (P<0.05). After 1 month of treatment, the masticatory function scores of 2 groups were significantly increased (P<0.05), and the experimental group was higher than the control group (P<0.05). The gingival index (GI) score and plaque index (PI) score of the experimental group were significantly lower than those of the control group (P<0.05), but there was no significant difference in probing depth (PD) between the two groups (P>0.05). The abutment sensitivity and pulp status, the color matching degree with neighboring teeth, the edge color of prosthesis and the grade distribution of prosthesis integrity in the experimental group were significantly better than these of the control group (P<0.05). There was no significant difference in the total incidence of complications between the two groups (P>0.05). CONCLUSIONS: Compared with resin repair, CAD/CAM porcelain veneer has better effect on anterior tooth space repair, which can improve patients' chewing function and periodontal health, enhance aesthetic effect, and reduce the risk of complications.
