摘要: 上颌后牙缺失时,由于缺乏牙的功能性刺激以及上颌窦气化作用导致种植所需的剩余骨高度不足,剩余骨量无法保证种植体的初始稳定性时,需要采取上颌窦底提升增加上颌后牙区骨量。“改良”上颌窦底内提升是通过使用富血小板纤维蛋白(platelet-rich fibrin,PRF),在内镜(endoscope)辅助下实现同期植入种植体(simultaneous implants placement)的一种改良的、微创的牙槽嵴入路上颌窦底提升(sinus floor elevation),简称“PESS”。“PESS”在一定程度上优化了上颌窦底提升,减小了手术创伤。本文阐述了“PESS”的原理、适应证、临床操作流程及注意事项,以期为“PESS”在临床中的应用提供技术支持。

Abstract: When posterior maxillary teeth are missing, the residual bone height required for implantation is insufficient due to the lack of functional stimulation from the teeth and pneumatization of the maxillary sinus. When residual bone volume cannot ensure the initial stability of the implant, a maxillary sinus floor elevation is needed to increase bone volume in the posterior maxillary region. The "PESS" procedure is a "modified" maxillary sinus floor elevation surgery that uses platelet-rich fibrin (PRF) as a single bone graft material, with the aid of an endoscope to elevate the maxillary sinus floor through the alveolar ridge and place implants simultaneously. The PESS procedure has optimized maxillary sinus floor elevation surgery to some extent and reduced surgical trauma. This article elaborates on the principles, indications, clinical procedures, and precautions of the "PESS" procedure to provide technical support for its clinical application.
