Sinus lift is a common procedure to achieve bone height in the maxillary posterior region. This surgery can be performed through either a lateral or crestal approach. Preoperative planning usually entails CBCT and intraoperative evaluation at the time of surgery. This article presents a case in which a surgical guide was made by digitally planning for the performance of a sinus lift procedure through a lateral approach.
A 59-year-old partially edentulous female patient underwent sinus lift surgery using a stereolithographic guide designed in NemoStudio software and printed using clear, biocompatible MED610. On the day of surgery, the bone guide was fixed with pins, and the lateral window was made by piezoelectric surgery. There were no intraoperative or postoperative incidents.
There are very few descriptions in the literature of the use of surgical guides for sinus lift. In this case, the advantages of its use were the precision in the performance of the window, the speed and comfort of access, and the retractor effect of the guide on the flap. The main drawback was the need to raise a wide flap to achieve good settlement of the guide.
The present case, which presents an innovative technique for the opening of the lateral window in a sinus lift procedure, is interesting for the advancement of computer-guided surgery.
鼻窦提升术是一种常见的方法，用于增加上颌后区的骨高度。该手术可以通过外侧或牙槽嵴顶入路进行。术前规划通常需要 CBCT，并在手术时进行术中评估。本文介绍了一个通过外侧入路数字化规划鼻窦提升手术的病例。
一位 59 岁的部分缺牙女性患者接受了使用立体光刻引导器进行的鼻窦提升手术，该引导器是在 NemoStudio 软件中进行数字规划，并使用透明、生物相容的 MED610 打印而成。在手术当天，使用销钉固定骨引导器，并通过压电手术制作外侧窗口。术中及术后均无并发症发生。
文献中很少有关于鼻窦提升手术中使用外科引导器的描述。在这种情况下，使用该引导器的优点是能够精确地进行窗口操作，提高手术速度和舒适度，并具有引导器对皮瓣的牵引效果。主要缺点是需要掀起较宽的皮瓣，以实现引导器的良好就位。
本病例提出了一种在鼻窦提升术中打开外侧窗口的创新技术，为计算机引导手术的发展提供了参考。
