The socket shield technique (SST)

The socket shield technique (SST) has gained great attention in the 14 years since its first publication. Different modifications of the original publication have been published in the meantime, with each one trying to become more predictable in the clinical outcome and prevent possible complications. For a better understanding of the mechanical and biologic principles of the SST, a novel 3D classification is developed and described in this article. This classification aims to help clinicians better anticipate and prevent the main long-term biologic complication of the SST, namely the coronal migration of the shield over time. In addition, this novel and clinically relevant 3D classification should allow for more effective and accurate communication between clinicians as well as a more objective assessment when it comes to the surgical execution of the SST.
