This article describes a case of indirect sinus lift augmentation using autogenous trephine alveolar bone cores and simultaneous placement of dental implants in a highly resorbed posterior maxillary region. In comparison to the direct sinus lift approach, the procedure described in this case report is less invasive, results in reduced treatment time, and yields a more predictable outcome. This procedure involves a mucosal incision followed by surgical exposure of the alveolar bone, and then using a trephine drill to create a bone trephine core. The Schneiderian membrane is then gently pushed up along with the bone trephine core using an osteotome and mallet, followed by simultaneous dental implant placement. Although this technique is skill-sensitive, it results in successful osseointegration of the implant with fewer complications.
本文描述了一例在高度吸收的上颌后牙区使用自体环钻牙槽骨骨芯进行间接窦底提升术并同时植入牙种植体的病例。与直接窦底提升术相比，本病例报告中描述的手术侵入性较小，治疗时间缩短，且预后更可预测。该手术包括黏膜切口，然后手术暴露牙槽骨，接着使用环钻钻取骨环钻芯。然后用骨凿和骨锤将上颌窦黏膜与骨环钻芯一起轻轻向上推，随后同时植入牙种植体。尽管该技术对操作技能要求较高，但能使种植体成功实现骨结合，且并发症较少。
