The socket-shield technique is a clinical procedure aimed at preventing both hard- and soft-tissue collapse following immediate implant placement. The technique can be challenging as multiple factors influence the precision of this treatment. Selective preservation of tooth (SPOT) is a standardized, reproducible tooth-guided preparation protocol for achieving a socket shield and for immediate post-extraction implant site preparation and placement. SPOT emphasizes the utilization of osseodensification burs in both forward (ie, clockwise) rotation, to allow for simultaneous precise root apex removal and shield preparation, and reverse (ie, counterclockwise) rotation, to allow for implant site preparation with further compaction-autografting of bone and dentin, thereby improving implant primary stability and its subsequent early healing. This article presents SPOT in a step-by-step protocol for socket-shield and implant site preparation with immediate post-extraction implant placement. The article describes the stepwise application for single-rooted teeth.
Socket-shield 技术是一种临床操作,旨在防止即刻种植体植入后软硬组织的塌陷。由于多种因素影响这种治疗的精度,因此该技术具有挑战性。选择性保留牙齿 (SPOT) 是一种标准化、可重复的牙齿引导预备方案,用于实现牙槽窝保护和即刻拔牙后种植体部位预备和植入。SPOT 强调在前向(即顺时针)旋转中使用骨密度增强磨头,以允许同时精确地去除根尖和预备牙槽窝,以及在后向(即逆时针)旋转中使用骨密度增强磨头,以允许进行种植体部位预备并进一步压实-自体骨和牙本质移植,从而提高种植体的初始稳定性及其随后的早期愈合。本文以分步协议介绍了即刻拔牙后植入体放置的牙槽窝保护和种植体部位预备的 SPOT。本文描述了适用于单根牙的逐步应用。
