Maxillary sinus augmentation is an accepted technique for dental implant placement in presence of insufficient maxillary bone. There are various techniques in the literature, either by crestal or lateral approach in maxillary sinus augmentation that have high percentage of success, while all have complications. Schneiderian membrane perforation is the most common complication encountered during surgery. The aim of this study was to evaluate the benefits of preoperative model surgery and the ease of use of a maxillary sinus surgical template (MSST) during maxillary sinus augmentation surgery with a lateral approach. Ten patients included in the study needed rehabilitation of a partially or totally edentulous maxilla with an implant-supported fixed prosthesis and requiring sinus augmentation. A questionnaire was asked to performing surgeons, and study results showed the use of an MSST was found to be effective in terms of adaptation (62.5%), window preparation (87.5%), ease of elevation (95.9%), ease of grafting (95.9%), reduction of perforation risk (91.7%), and achieving immobility during the procedure (62.5%); however, the use of an MSST was also found to prolong the surgical procedure (100%) and restrict the view of the surgical area (79.2%). Maxillary sinus augmentation appears to be a useful tool for locating an appropriate entrance to the sinus cavity, allowing for safe elevation of the sinus membrane and effectively grafting the sinus floor.
在上颌骨骨量不足的情况下，上颌窦提升术是一种被广泛认可的牙种植体植入技术。文献中介绍了多种技术，无论是通过牙槽嵴顶入路还是侧方入路进行上颌窦提升，成功率都很高，但均存在并发症。施奈德膜穿孔是手术中最常见的并发症。本研究的目的是评估术前模型手术的益处以及在上颌窦侧方提升术中使用上颌窦手术模板（MSST）的便利性。本研究纳入的10例患者需要通过种植体支持的固定修复体修复部分或全部无牙的上颌骨，且需要进行窦腔提升。对手术医生进行了问卷调查，研究结果显示，MSST在适配性（62.5%）、开窗制备（87.5%）、提升便利性（95.9%）、植骨便利性（95.9%）、降低穿孔风险（91.7%）以及手术过程中实现固定（62.5%）方面被证明是有效的；然而，使用MSST也被发现会延长手术时间（100%）并限制手术区域的视野（79.2%）。上颌窦提升术似乎是一种有用的工具，可用于确定进入窦腔的合适入口，确保安全提升窦膜并有效地对上颌窦底进行植骨。
