Objective: To explore the clinical application value of orthodontic treatment in oral aesthetic restoration and provide evidence for optimizing aesthetic restoration protocols. Methods: A total of 120 patients requiring oral aesthetic restoration admitted to our hospital from July 2024 to July 2025 were randomly divided into an observation group (60 cases) and a control group (60 cases) using a random number table method. The control group received conventional oral aesthetic restoration therapy, while the observation group underwent personalized orthodontic treatment prior to the same restoration protocol. Comparative analysis was conducted on pre-and post-treatment aesthetic scores (tooth alignment, occlusal relationship, gingival health, facial harmony), occlusal function indicators (biting force, chewing efficiency), restoration retention rates, and patient satisfaction, with adverse reaction records. Results: Post-treatment aesthetic scores (tooth alignment: 9.12±0.68; occlusal relationship: 9.25±0.57) in the observation group were significantly higher than those in the control group (P<0.05). The observation group also demonstrated superior biting force (586.32±45.17 N) and chewing efficiency (89.26±5.34%) (P<0.05). The observation group achieved a 1-year restoration retention rate of 96.67% and satisfaction rate of 98.33%, both significantly higher than the control group"s 81.67% and 78.33% (P<0.05). No statistically significant difference was observed in adverse reaction rates between the two groups (P>0.05). Conclusion: Implementing orthodontic treatment before oral aesthetic restoration can significantly enhance aesthetic outcomes and occlusal function, improve restoration stability and patient satisfaction, demonstrating reliable safety and significant clinical value.
