上颌前牙种植对美学和功能有较高要求,但其唇侧骨板较薄术后易吸收,影响种植美学与功能的实现。根盾技术(SST)因保留唇侧部分牙根和牙周膜血供,可阻止拔牙后的生理性骨吸收,从而保存完整的唇侧骨板。经过10余年的实验与发展,该技术已成熟应用于临床,拥有特定的操作流程,能够最大限度地保留种植术后的软硬组织,达到最佳的种植修复效果。然而,其适应证严格,技术敏感性高。本文结合国内外研究现状及笔者团队多年来的临床应用经验,对SST的病例选择、根盾设计和操作流程等进行详细的总结和阐述,分析现存问题及未来发展方向,以期为SST的临床应用和推广提供参考。

Implant treatment in the maxillary anterior region requires favorable esthetic and functional outcomes. The buccal bone plate in this region is often thin and prone to resorption after tooth extraction, which may compromise treatment outcomes. The socket shield technique preserves part of the buccal root and the periodontal ligament blood supply, thereby helping to reduce post-extraction bone resorption and maintain the buccal bone plate. After more than 10 years of development, this technique has been increasingly applied in clinical practice and has shown advantages in preserving peri-implant hard and soft tissues. However, it is still associated with strict indications and high technical sensitivity. Based on current literature and our clinical experience, this article reviews case selection, shield design, surgical procedures, current limitations, and future directions of the socket shield technique, with the aim of providing a reference for its clinical application.
