Objective To analyze the clinical effect of immediate implant restoration of maxillary anterior teeth. Methods From March 2021 to March 2022, 48 patients with single tooth defect of maxillary anterior teeth treated in our hospital were selected as the research objects. According to different treatment methods, the patients were divided into observation group (n=24) and control group (n=24). The control group was given delayed implantation and delayed restoration of single maxillary anterior teeth, and the observation group was given immediate implant restoration of single maxillary anterior teeth. The changes of alveolar ridge width, probing depth, soft tissue modified gingival sulcus bleeding index, pink esthetic score, planting success rate and planting satisfaction were compared between the two groups. Results The alveolar ridge widths of M4, M3, M2 and M1 in the observation group were greater than those in the control group at 12 months after treatment (P<0.05). At 12 months after treatment, the probing depth and soft tissue modified gingival sulcus bleeding index in the observation group were lower than those in the control group, and the pink esthetic score was higher than that in the control group (P<0.05). The scores of overall aesthetics, chewing function, color and total score in the observation group were higher than those in the control group (P<0.05). The success rate of implantation in the observation group was higher than that in the control group (P<0.05). Conclusion Immediate implant restoration of single tooth in maxillary anterior teeth is effective in repairing single tooth defect in maxillary anterior teeth, which can reduce bone resorption, facilitate bone tissue growth, and improve soft tissue function around the implant. Meanwhile, it can improve the success rate of implantation while ensuring aesthetics, and the patient satisfaction is high.
