摘　　要：目的评估应用牙片屏障技术行美学区即刻种植、即刻修复后5年的临床效果。方法纳入2013年7月至2020年7月于北京大学口腔医学院·口腔医院第四门诊部就诊,应用牙片屏障技术行美学区即刻种植的患者29例,共34枚种植修复体,评估术后(60.2±26.7)个月(13~101个月)种植体存留、并发症发生情况及粉色美学指数评分,通过治疗前和末次随访时的数字化模型对比,测量软组织变化情况。通过术后即刻和末次随访时的锥形束CT测量,观察唇侧牙槽骨变化情况。结果34枚种植体全部存留,粉色美学指数评分(12.80±1.05)分,各个牙位的评分差异无统计学意义(F=1.77,P=0.150)。唇侧龈缘退缩量为(0.12±0.09)mm,龈顶点根方2 mm处软组织轮廓退缩为(0.45±0.17)mm。唇侧牙槽骨高度降低(0.14±0.46)mm。结论应用牙片屏障技术行即刻种植即刻修复可维持唇侧软组织形态和轮廓,维持牙槽骨高度,获得良好的美学效果。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.
