RESUMO
Objective: To evaluate the clinical effect of socket-shield technique for 5 years after immediate implantation and immediate restoration in aesthetic area. Methods: The retrospective study was conducted between July, 2013 and July, 2020. A total of 29 patients, with 34 implants, who received immediate implantation and immediate restoration with socket-shield technique in the esthetic zone in Department of Fourth Clinical Division, Peking University School and Hospital of Stomatology were included in this study. The implants survival rate, complications and the pink esthetic score (PES) were evaluated (60.2±26.7) months (13-101 months) after operation. The digital models before treatment and at the final follow-up were obtained, to measure the changes of soft tissue. The labial alveolar bone recession was measured by cone-beam CT. Results: All 34 implants survived during follow-up. The PES was (12.80±1.05), there was no significant difference in PES scores between dental positions (F=1.77, P=0.150). The gingival margin recession was (0.12±0.09) mm, and labial contour change at 2 mm apical to the gingival zenith was (0.45±0.17) mm. The labial alveolar bone recession was (0.14±0.46) mm. Conclusions: Immediate implant with socket-shield technique could maintain the gingival margin and labial alveolar bone, and preserve the soft tissue contour well to achieve good esthetic outcome.
