摘　　要：目的:比较美学区运用根盾技术(socket shield technique,SST)与常规即刻种植术治疗的临床效果,探讨该技术维持上颌前牙美学区软硬组织的美学效果。方法:收集2017年10月~2022年10月在前牙美学区行即刻种植修复的患者30例,随访12个月,15例设为实验组使用根盾技术修复,15例设为对照组使用常规即刻种植术修复。术前术后拍摄CBCT,统计两组种植体成功率,测量对比两组距种植体肩台0 mm(0 mm-IS)、3 mm(3 mm-IS)、6 mm(6 mm-IS)的唇侧水平骨板变化,使用红色美学指数(pink esthetic score,PES)以及患者满意度评价修复效果。结果:两组种植体成功率均为100%,未出现种植体并发症。术后1年两组距种植体肩台0 mm(0 mm-IS)、3 mm(3 mm-IS)、6 mm(6 mm-IS)的唇侧水平骨板厚度与术后即刻测量骨板厚度相比,实验组术后即刻与术后1年差异无统计学意义(P>0.05),对照组差异有统计学意义(P<0.05)。实验组PES评分(13.27±0.80)高于对照组(12.20±0.78),差异有统计学意义(P<0.05);实验组与对照组均获得较高的患者满意度,评分分别为(9.27±0.70)和(9.13±0.92)。结论:根盾技术对比于常规即刻种植术在短期内可以较好地维持唇侧软硬组织轮廓,唇侧保留的牙片对种植成功率无明显影响,但根盾技术敏感性较强且应严格掌握手术适应症。Objective:To compare the clinical study on outcomes of socket shield technique(SST)versus conventional immediate implant placement in the aesthetic zone,and discuss the esthetic outcomes of SST maintaining the hard and soft tissues in the aesthetic zone.Methods:Thirty patients who underwent immediate implant placement in the aesthetic area of anterior teeth from October 2017 to October 2022 were collected and followed up for 12 months,15 cases were assigned to the experimental group using socket shield technique and 15 cases to the control group using conventional immediate implantation,with a 1-year follow-up,CBCT was taken to count the success rate of implants in both groups.The amount of bone resorption at the labial level at 0 mm(0 mm-IS),3 mm(3 mm-IS)and 6 mm(6 mm-IS)from the implant shoulder,the esthetic outcomes was assessed using pink esthetic score(PES)and patient satisfaction.Results:One year after surgery,the implant success rate of both groups was 100%,and no implant complications occurred.The differences in the thickness of the bone plate at the labial level at 0 mm(0 mm-IS),3 mm(3 mm-IS),and 6 mm(6 mm-IS)from the implant shoulder in the test group were not statistically significant compared to the immediate postoperative period(P>0.05),however,the opposite results were obtained in the control group(P<0.05).In the test group the PES(13.27±0.80)was higher than in the control group(12.20±0.78),and the difference was statistically significant(P<0.05),both groups obtained higher patient satisfaction,the scores of patient satisfaction in the two groups were(9.27±0.70)and(9.13±0.92).Conclusion:Compared with the conventional immediate implantation,the socket shield technique can maintain the soft and hard tissue contour of the labial side well in the short term.The retained labial fragments have no significant effect on the success rate of implantation.However,the socket shield technique is highly sensitive and the surgical indications should be strictly mastered.
