Background. Long-term edentulism may in many cases result in resorption of the alveolar process. The sinus lift procedure aims to create increased bone volume in the maxillary sinus in order to enable installation of dental implants in the region. The method is over 30 years old, and initially autogenous bone grafts were used and later also different bone substitutes. Since 1997, a limited number of studies have explored the possibility of a graftless procedure where the void under the sinus membrane is filled with a blood clot that enables bone formation. Aim. To describe the evolution of the sinus-lift technique and to review the literature related to the technique with a focus on long-term studies related to the graft-less technique. Methods. The electronic database PubMed was searched, and a systematic review was conducted regarding relevant articles. Results. A relatively few long-term studies using the described technique were found. However, the technique was described as reliable considering the outcome of the existing studies. Conclusion. All investigated studies show high implant survival rates for the graftless technique. The technique is considered to be cost-effective, less time-consuming, and related to lower morbidity since no bone harvesting is needed.
背景。在许多情况下，长期无牙会导致牙槽突吸收。上颌窦提升术旨在增加上颌窦内的骨量，以便能够在该区域植入牙种植体。该方法已有30多年历史，最初使用自体骨移植，后来也使用了不同的骨替代物。自1997年以来，有限数量的研究探讨了无移植手术的可能性，即在上颌窦膜下方的空隙中填充血凝块以促进骨形成。目的。描述上颌窦提升技术的演变，并回顾与该技术相关的文献，重点关注与无移植技术相关的长期研究。方法。检索电子数据库PubMed，并对相关文章进行系统综述。结果。发现使用所述技术的长期研究相对较少。然而，考虑到现有研究的结果，该技术被描述为可靠。结论。所有调查研究均显示无移植技术的种植体存活率很高。该技术被认为具有成本效益、耗时较少且发病率较低，因为无需采集骨组织。
