Objective To investigate the application effect of immediate implantation using socket-shield technique(SST)in the restoration of diseased teeth in the anterior maxilla.Methods Twenty-two patients who underwent immediate implantation in the anterior maxilla at Department of Stomatology,the First Hospital of Zhangjiakou City from April 2020 to January 2023 were selected.They were divided into the flapless group(conventional flapless immediate implant restoration)and the socket-shield group(immediate implant restoration using SST)according to the random number table method,with 11 patients in each group.The implant survival rate at 36 months postoperatively,hard tissue resorption at different sites of the implants[the difference in the facial bone width(FBW),total bone width(BW),and facial bone height(FBH)immediately after surgery and at 36 months postoperatively(ΔFBW,ΔBW,ΔFBH)],the changes in the soft tissue of the implants[pink esthetic score(PES),changes in the labial contour prominence,changes in the labial gingival margin],patient satisfaction,and the incidence of complications were compared between the two groups.Results As of the last follow-up,all 22 implants were stable with no significant bone resorption,and all were able to function normally.The implant survival rate in both groups was 100%(11/11),and the difference was not statistically significant(P>0.05).The ΔFBW and ΔBW at the 0-mm horizontal level of the abutment shoulder and the mid-root level of the implant in the socket-shield group were lower than those in the flapless group,and the ΔFBH was also lower than that in the flapless group(P<0.05).There was no significant difference in the intraoral photographs and PES scans between the two groups(P>0.05),but the changes in the labial contour prominence and the labial gingival margin position in the root-membrane group were smaller than those in the flapless group(P<0.05).There was no significant difference in patient satisfaction and complication rates between the two groups(P>0.05).Conclusion Immediate implantation using SST for immediate implantation in the restoration of diseased teeth in the anterior maxilla has promising clinical effectiveness.It can effectively reduce labial bone plate resorption and soft tissue recession,while also contributing to improved aesthetic outcomes and patient satisfaction,without increasing the incidence of complications.
