The edentulous posterior maxilla is considered a clinical challenge during dental implant treatment for many dental practitioners. This is because its insufficient bone quality, deficient alveolar ridge, spiny ridges, undercuts, and sinus pneumatization are often encountered after tooth loss. To overcome these problems, several approaches have been developed and are currently used, including sinus augmentation and bone augmentation. Today, two main procedures of sinus floor elevation for dental implant placement are in use: a two-stage technique using the lateral window approach, and a one-stage technique using a lateral or a crestal approach. In this study, we deal with the anatomic relations of the structures of the maxillary sinus during sinus augmentation. These anatomical findings can help in complications and potential injuries of the maxillary sinus procedures. It can be suggested that pre-operative evaluation is helpful for diagnosis and treatment planning and minimizing complication during the surgery.
对于许多牙科从业者而言，无牙上颌后牙区在牙种植治疗期间被视为一项临床挑战。这是因为牙齿缺失后常出现骨质不足、牙槽嵴缺损、棘状嵴、倒凹以及鼻窦气化等情况。为克服这些问题，已研发并正在使用多种方法，包括鼻窦增高术和骨增量术。如今，用于牙种植体植入的鼻窦底提升主要有两种方法：采用侧窗入路的两阶段技术，以及采用侧方或嵴顶入路的单阶段技术。在本研究中，我们探讨了鼻窦增高术期间上颌窦结构的解剖关系。这些解剖学发现有助于了解上颌窦手术的并发症和潜在损伤。可以认为术前评估有助于诊断和治疗计划制定，并可在手术期间将并发症降至最低。
