The extension of sinus floor augmentation beyond the edentulous area, apical to the adjacent teeth, has many therapeutic advantages, but the reliability and safety of the procedure has not been assessed in depth. The present study compares the gain of bone anterior and posterior to the edentulous area and evaluates potential advantages and limitations in the clinical setting. The maximum vertical bone height in the edentulous and extended maxillary sinus augmentation (EMSA) areas and the thickness of the sinus membrane of 65 patients were measured. Those measurements were analyzed using the t test and Pearson correlations. The average vertical bone gain was 11.98 ± 3.53 mm in the edentulous sinus area and 8.60 ± 3.89 mm in the EMSA area (P < .05). Minor perforations of the sinus membrane occurred in 4 patients. There were no postsurgical graft contaminations or periradicular changes during follow-up. EMSA is a reliable and safe procedure with a very low complication rate. This approach is effective and safe for patients who have lost part of their posterior dentition. It enables future implant placement while avoiding the need for sinus reentry and proximal teeth extraction.
上颌窦底提升延伸至无牙区以外、邻牙根尖部位具有诸多治疗优势，但该手术的可靠性和安全性尚未得到深入评估。本研究比较了无牙区前后方的骨增量，并评估了临床环境中的潜在优势和局限性。测量了65例患者无牙区和上颌窦延伸提升术（EMSA）区域的最大垂直骨高度以及窦膜厚度。使用t检验和Pearson相关性分析这些测量结果。无牙区上颌窦区域的平均垂直骨增量为11.98±3.53mm，EMSA区域为8.60±3.89mm（P<.05）。4例患者出现窦膜轻微穿孔。随访期间未发生术后植骨污染或根尖周改变。EMSA是一种可靠、安全的手术，并发症发生率极低。该方法对后牙列部分缺失的患者有效且安全。它能够在未来进行种植体植入，同时避免上颌窦再次开窗和拔除邻牙的需要。
