Observation of the application of socket shield technique in the immediate implantation of a single tooth in the aesthetic region of maxilla

[Objective:] To observe the application of socket shield technique in immediate implantation of single tooth in maxillary anterior region and its effect on labial bony plate and aesthetic effect. [Methods:] Seventy patients who underwent single maxillary anterior dental implant restoration in our department from September 2019 to September 2021 were selected for this study. The patients were randomly divided into control group (35 cases, immediate implantation) and observation group (35 cases, socket shield technique combined with immediate implantation) according to envelope method. The success rate, complication rate, absorption of labial bone plate, change of soft tissue height, aesthetic effect and satisfaction were compared between the two groups. [Results:] After 12 months of repair, the pink esthetic score (PES), white esthetic score (WES) and satisfaction of the observation group were better than those of the control group (P<0.01), while the absorption of the labial bone plate and the change of soft tissue height were less than those of the control group (P<0.05). The success rate of the observation group was 97.14%, and the complication rate was 2.86%; the success rate of the control group was 94.29%, and the complication rate was 11.43%. There was no significant difference between the two groups in the success rate and the complication rate (P>0.05). [Conclusion:] The application of socket shield technique in immediate implantation of single tooth in maxillary anterior region can reduce the absorption amount of labial bone plate, reduce gingival atrophy, improve aesthetic effect, improve patient satisfaction, and it is safe and effective.
