Tooth extraction is a traumatic procedure initiating a complex cascade of biochemical and histologic events that inevitably lead to a reduction of alveolar bone and soft tissue. These tissue alterations often lead to an esthetic compromise of the future implant restoration. The hard- and soft-tissue architecture surrounding the extraction defect largely dictates the course of dental implant treatment. The EDS or extraction-defect sounding classification is a novel system introduced to simplify the decision-making process when planning for dental implant therapy following tooth extraction. Dental implant treatment guidelines based on the EDS classification are discussed. A review of pretreatment evaluations necessary to prepare for esthetic implant procedures is also presented.
拔牙是一种创伤性操作，会引发一系列复杂的生化和组织学事件，不可避免地导致牙槽骨和软组织减少。这些组织改变常常会导致未来种植修复体的美学效果受损。拔牙窝周围的软硬组织结构在很大程度上决定了牙种植治疗的进程。EDS或拔牙窝探查分类是一种新系统，旨在简化拔牙后牙种植治疗计划时的决策过程。本文讨论了基于EDS分类的牙种植治疗指南。还介绍了为美学种植手术做准备所需的术前评估。
