The aim of this study was to evaluate the clinical relevance of autogenous fresh demineralized tooth (Auto-FDT) prepared at chairside immediately after extraction for socket preservation. Teeth were processed to graft materials in block, chip, or powder types immediately after extraction. Extraction sockets were filled with these materials and dental implants were installed immediately or after a delay. A panoramic radiograph and a conebeam CT were taken. In two cases, tissue samples were taken for histologic examination. Vertical and horizontal maintenance of alveolar sockets showed some variance depending on the Auto-FDT and barrier membrane types used. Radiographs showed good bony healing. Histologic sections showed that it guided good new bone formation and resorption pattern of the Auto-FDT. This case series shows that Auto-FDT prepared at chairside could be a good material for the preservation of extraction sockets. This study will suggest the possibility of recycling autogenous tooth after immediate extraction.
本研究的目的是评估拔牙后立即在椅旁制备的自体新鲜脱矿牙（Auto-FDT）用于牙槽窝保存的临床相关性。拔牙后立即将牙齿加工成块状、片状或粉末状的移植材料。将这些材料填充到拔牙窝中，并立即或延迟后植入牙种植体。拍摄全景X线片和锥形束CT。在两例病例中，采集组织样本进行组织学检查。牙槽窝的垂直和水平维持情况因所使用的Auto-FDT和屏障膜类型而异。X线片显示骨愈合良好。组织学切片显示其引导了Auto-FDT良好的新骨形成和吸收模式。该病例系列表明，在椅旁制备的Auto-FDT可能是保存拔牙窝的良好材料。本研究将提示立即拔牙后自体牙再利用的可能性。
