The edentulous posterior maxilla poses challenges to reconstruction. Posterior forces are great, yet bone quality and quantity are diminished. There is frequent loss of bone resulting from ridge resorption as well as sinus pneumatization. There are also advantages of placing implants in the posterior maxilla compared with the anterior maxilla, such as improved hygiene, esthetics and phonetics, and biomechanical load distribution. This article will present strategies and techniques for improving implant support in the posterior maxilla through various grafting techniques.
无牙上颌后部的重建面临挑战。后部受力较大，但骨质量和骨量却有所减少。由于牙槽嵴吸收以及上颌窦气化，骨丢失频繁发生。与上颌前部相比，在上颌后部植入种植体也有一些优势，例如改善口腔卫生、美观和语音，以及生物力学负荷分布。本文将介绍通过各种植骨技术改善上颌后部种植体支持的策略和技术。
