Inadequate alveolar bone height/volume and sinus anatomy can complicate the predictable placement of conventional implants and subsequent restoration in posterior maxillary sites. A variety of sinus lift and vertical bone height augmentation materials and techniques have been utilized for this purpose; however, generally they are clinically challenging, demand well-trained surgical proficiency, and require the use of multiple armamentaria. Simultaneously, clinicians must meticulously handle the sinus membrane to achieve elevation without perforation, attain successful bone grafting, and ensure predictable implant osseointegration. The hydraulic sinus condensing (HSC) technique via the osteotomy site is designed to be less invasive than conventional sinus lift techniques, reduce trauma to patients, improve implant osseointegration into grafted alveolar bone, prevent sinus membrane perforation, and enhance the overall efficiency of the associated surgical process. This article briefly reviews the evolution of sinus lift and posterior maxillary implant insertion procedures and presents a case in which the HSC technique and a uniquely designed sinus implant were used.
牙槽骨高度/体积不足以及窦腔解剖结构会使在上颌后牙区常规种植体的可预测植入及后续修复变得复杂。为此已采用了多种窦底提升和垂直骨高度增加材料及技术；然而，一般来说它们在临床上具有挑战性，需要训练有素的手术技能，并且需要使用多种器械。同时，临床医生必须小心处理窦膜以实现提升而不穿孔，成功进行骨移植，并确保种植体可预测的骨整合。经截骨部位的液压窦腔挤压（HSC）技术旨在比传统窦底提升技术的侵入性更小，减少对患者的创伤，改善种植体与移植牙槽骨的骨整合，防止窦膜穿孔，并提高相关手术过程的整体效率。本文简要回顾了窦底提升和上颌后牙种植体植入手术的发展历程，并介绍了一个使用HSC技术和独特设计的窦腔种植体的病例。
