根盾技术在上颌单颗前牙即刻种植修复中的美学效果与临床分析OA

Objective This study aims to investigate the clinical efficacy of the socket-shield technique in immediate implant restoration of a single maxillary anterior tooth in a retrospective study.Methods A total of 86 patients who underwent immediate implant restoration of a single maxillary anterior tooth at our hospital from April 2021 to March 2022 were selected and divided into two groups according to different implant surgical techniques,with 43 patients in each group.The socket-shield technique group(experimental group)received immediate implant placement combined with the root membrane technique,while the conventional implant group(control group)underwent minimally invasive tooth extraction followed by immediate implant placement.Implant survival rate,complication rate,and patient satisfaction were compared between the two groups.Additionally,probing depth(PD),pink esthetic score(PES),white esthetic score(WES),and modified bleeding index(mBI)were assessed pre-and postoperatively between the two groups.Results The implant retention rate was 95.35%in the socket-shield technique group and 88.37%in the conventional implant group,with no statistically significant difference between the two groups(P=0.237).Patient satisfaction in terms of soft tissue color,overall esthetics,chewing comfort,and total score was significantly higher in the experimental group(P<0.001),with scores of(8.72±0.90),(9.13±0.54),(8.45±0.67),and(25.36±1.42),respectively,compared with(7.36±1.45),(8.22±1.30),(7.01±1.63),and(22.59±1.74)in the control group.Preoperatively,there were no significant differences in PES,mBI,and PD between the two groups(P>0.05).Postoperatively,PES and WES were significantly higher in the experimental group[(8.68±0.89)and(9.01±0.33)]than in the control group[(7.25±1.41)and(8.30±0.76)](P<0.001).The socket-shield technique group also exhibited significantly lower mBI and PD values[(0.27±0.08)and(2.35±0.68)mm]than the control group[(1.39±0.36)and(3.27±0.91)mm](P<0.001).Additionally,the complication rate in the socket-shield technique group was 9.30%,which was not significantly different from that in the conventional implant group(13.95%;P=0.501).Conclusion Both treatment modalities demonstrated high Implant retention rates and safety profiles.However,the socket-shield technique exhibited superior esthetic outcomes and higher patient satisfaction in the immediate implant restoration of a single maxillary anterior tooth,making it worthy of broader clinical application and promotion.
