摘要：

上颌窦底提升术是解决上颌后牙区种植修复所需余留骨高度（residual bone height, RBH）不足时的常用治疗方法。目前，对于上颌窦内的成骨机制、上颌窦底提升术术式的选择、同期种植的时机、年龄或性别的影响、是否需要置入骨替代材料等问题众说纷纭。本文根据种植科团队有关上颌窦内成骨机制的研究成果，结合本院种植科10余年上颌窦底提升术的治疗效果，总结临床操作的方法与技巧，以期达到理论研究与临床实践相结合并最终指导临床的转化医学模式，提出了更加优化的、简单易行的上颌窦底提升术的方案与理念，即经牙槽嵴顶上颌窦底提升术+浓缩生长因子（concentrated growth factors, CGF）+同期植入种植体。

Abstract:

The maxillary sinus floor elevation surgery through the crest of the alveolar ridge is a commonly used method to solve the problem of insufficient residual bone height (RBH) required for implant restoration in the posterior maxillary region. There are currently many controversies relating to this operation, including the mechanism of osteogenesis in the maxillary sinus, the selection of surgical methods for maxillary sinus floor elevation, the timing of simultaneous implantation, the impact of age or gender, and the need for bone substitutes. Based on the research of our group on the mechanism of maxillary sinus osteogenesis, combined with the treatment effect of maxillary sinus floor elevation surgery in the Department of Oral Implantology in our hospital for over 10 years. This article summarizes the clinical operation rules and internal correlations in order to achieve the translational medicine model that combines theoretical research with clinical practice and ultimately guides clinical practice. A summary of the methods and techniques for clinical operations has been outlined in order to achieve a combination of theoretical research and practical clinical guidance, proposing a more optimized and simplified solution and the concept for maxillary sinus floor elevation surgery called transalveolar maxillary sinus floor elevation (TSFE), which involves the use of concentrated growth factors (CGF) and simultaneous implantation of dental implants.

Key words: maxillary sinus floor elevation, transalveolar maxillary sinus floor elevation, concentrated growth factors, bone augmentation
