This study aimed to collect data on implant survival, bone volume maintenance, and complications associated with the socket shield technique. The socket shield technique was introduced in 2010. Since then, several systematic reviews have been published that show good clinical outcomes. So far, the behavior of the buccal bone plate is not completely understood. The present study involved the placement of 23 implants in 20 patients using the socket shield technique. AstraTech EV im- plants were used, and no bone substitutes or connective tissue grafts were applied. Patients were monitored for 18 months, recording implant survival, volumetric bone analysis on CBCT scans, interproximal bone levels, bone sounding, pink esthetic scores, and complications. Prosthetic procedures were also described, including temporary and final restorations. Using the socket shield technique, a cumulative implant survival rate of 95.7% was obtained after 18 months, with a significant but limited reduction in buccal bone thickness (BBT) after implant placement. One implant did not integrate, and two shields were partially exposed. The mean pink esthetic score at 1 year postloading was 12.93 ± 1.22. The study suggests that the socket shield technique can result in a limited reduction of the buccal bone volume, with a high implant survival rate. Reentry studies are recommended to investigate the causes of bone resorption.
本研究旨在收集与牙槽窝保护技术相关的种植体存留率、骨量维持情况及并发症的数据。牙槽窝保护技术于2010年被引入。自那时起，已有数篇系统评价发表，显示出良好的临床效果。到目前为止，颊侧骨板的行为尚未完全明确。本研究使用牙槽窝保护技术为20例患者植入了23枚种植体。使用的是AstraTech EV种植体，未应用骨替代材料或结缔组织移植。对患者进行了18个月的监测，记录种植体存留情况、CBCT扫描的骨体积分析、邻间骨水平、骨探测、粉色美学评分及并发症。还描述了修复程序，包括临时和最终修复。采用牙槽窝保护技术，18个月后种植体累积存留率为95.7%，种植体植入后颊侧骨厚度（BBT）有显著但有限的减少。1枚种植体未成功骨结合，2个牙槽窝保护装置部分暴露。加载后1年的平均粉色美学评分为12.93±1.22。该研究表明，牙槽窝保护技术可导致颊侧骨量有限减少，种植体存留率高。建议进行再次研究以调查骨吸收的原因。
