Objective:To investigate the clinical effectiveness of photocurable composite resin in minimally invasive aesthetic oral restoration.Methods:A total of 60 patients who underwent minimally invasive aesthetic restoration of anterior teeth or premolars in the Department of Stomatology of our hospital from May 2023 to April 2025 were enrolled. According to the restoration method, patients were divided into a control group (metal–ceramic restoration) and an observation group (photocurable composite resin restoration), with 30 cases in each group. All patients were followed up for 6 months. Restorative efficacy, aesthetic restoration quality, periodontal health indicators, and the incidence of adverse reactions were compared between the two groups.Results:The total effective rate in the observation group was 96.67%, which was significantly higher than that in the control group (80.00%) (P < 0.05). The rates of grade A restoration integrity, marginal adaptation, and absence of discoloration were all higher in the observation group than in the control group (P < 0.05). After treatment, GI, SBI, PLI, and PD were significantly reduced in both groups compared with baseline, with lower values observed in the observation group (P < 0.05). The incidence of adverse reactions in the observation group was 6.67%, which was lower than that in the control group (26.67%) (P < 0.05).Conclusion:Photocurable composite resin applied in minimally invasive aesthetic oral restoration can achieve favorable aesthetic and functional outcomes while preserving dental hard tissue, improve periodontal health, and demonstrate good clinical safety.
