Objective To compare the effects of porcelain veneer and porcelain crown in aesthetic restoration of anterior teeth loss. Methods A total of 150 patients with anterior teeth loss who underwent elective aesthetic restoration at Shanghai Huangpu Dental Disease Prevention and Treatment Center from March 2021 to May 2024 were selected as the research subjects, and they were divided into the control group and the study group by the random number table method, with 75 patients in each group. The control group received porcelain crown aesthetic restoration, and the study group received porcelain veneer aesthetic restoration. The restoration effect, periodontal related indexes and aesthetic restoration satisfaction were compared between the two groups. Results The total effective rate of restoration in the study group was 98.67%, which was higher than 89.33% in the control group (P <0.05). After 3 months of restoration, the plaque index and gingival index in the two groups were lower than those before restoration, and those in the study group were lower than those in the control group (P <0.05). The aesthetic restoration satisfaction in the study group was 100.00%, which was higher than 90.67% in the control group (P <0.05). Conclusion Compared with porcelain crown, porcelain veneer has better effects in aesthetic restoration of anterior teeth loss, which can effectively improve patients' periodontal indexes and achieve higher satisfaction with aesthetic restoration.
