【】Objective: To evaluate the visual effect and safety feasibility of zirconia all-ceramic crowns in dental cosmetic restoration. Methods: From January 2023 to January 2025, 100 patients undergoing dental cosmetic restoration were enrolled and divided based on odd or even appointment numbers, with 50 cases in each group: the conventional group (using traditional porcelain-fused-to-metal crowns) and the experimental group (using zirconia all-ceramic crowns). Differences in treatment outcome, visual effect, masticatory efficiency, and safety were analyzed. Results: Regarding treatment effect, the experimental group scored higher than the conventional group (P<0.05). For visual effect, scores in the experimental group were higher (P<0.05). Masticatory efficiency and occlusal force showed no difference between groups before restoration (P>0.05), but after restoration, the experimental group was higher (P<0.05). In terms of safety, the experimental group showed better outcomes (P<0.05).Periodontal health is an inter-group assessment item, with no significant difference (P>0.05) observed before restoration. However, the analysis group showed a lower level after 6 and 12 months of restoration (P<0.05). Oral functional comfort is also an inter-group assessment item, with no significant difference (P> 0.05) observed before restoration. However, the analysis group demonstrated a lower level after 6 and 12 months of restoration (P<0.05). Conclusion: Zirconia all-ceramic teeth have achieved ideal results in dental cosmetic restoration. They can enhance the visual aesthetics of patients" teeth, optimize dental function, reduce the occurrence of gingivitis, marginal disintegration, and secondary caries, and continuously improve periodontal health and oral functional comfort. They meet clinical needs and have certain promotion and application value.
