Objective To analyze the application effect of direct restorations using adhesive composite resins in the aesthetic restoration of anterior teeth. Methods A total of 158 patients with aesthetic restoration of anterior teeth in Yangzhong Yin's Dental Clinic from January 2020 to August 2021 were selected as the research objects, and they were randomly divided into the control group and the observation group, with 79 cases in each group. The control group was treated with conventional repair technology, and the observation group was treated with direct restorations using adhesive composite resins. The clinical efficacy, repair effect, repair satisfaction and adverse events of the two groups were compared. Results The clinical excellent rate of the observation group was higher than that of the control group (P＜0.05). The scores of tooth space, incisor defect, abnormal small teeth, tooth coloring or discoloration and tooth surface defect in the observation group were lower than those in the control group (P＜0.05). The repair satisfaction of the observation group was higher than that of the control group (P＜0.05). There was no significant difference in the incidence of adverse events between the two groups (P＞0.05). Conclusion The application of composite resin direct bonding repair technology in aesthetic restoration of anterior teeth is more accurate, safe and reliable, which is worthy of clinical application.
