Objective To compare the restoration effect of porcelain veneer and all-ceramic crown on the aesthetics of anterior teeth and its influence on gingival crevicular fluid related indexes. Methods A total of 80 patients with anterior teeth defect admitted to the Department of Stomatology, Handan Yongjian Lihua Dental Clinic from March 2023 to March 2024 were selected and randomly divided into the control group (n =40) and the observation group (n =40). The control group was given all-ceramic crown for anterior teeth restoration, and the observation group was given porcelain veneer for anterior teeth restoration. The aesthetic effect, restoration effect, gingival crevicular fluid indexes and adverse reactions were compared between the two groups. Results After 3 months of treatment, the scores of appearance, color match and surface texture in the observation group were higher than those in the control group (P <0.05). The total effective rate of restoration in the observation group (95.00%) was higher than that in the control group (85.00%), but the difference was not statistically significant (P >0.05). After treatment, GCF and ALP in the observation group were better than those in the control group (P <0.05). The incidence of adverse reactions in the observation group (5.00%) was lower than that in the control group (20.00%) (P <0.05). Conclusion Porcelain veneer and allceramic crown have a good restoration effect on anterior teeth restoration. Porcelain veneer is more effective in aesthetics and adverse reactions, and is more conducive to maintaining periodontal health.
