Cone-beam computed tomography (CBCT) scans are used in planning implant treatment to help determine volume of available bone and identify anatomical structures. This enhances planning, particularly when inadequate bone is present in the posterior maxilla due to proximity of the inferior aspect of the maxillary sinus to the crestal bone. To place dental implants into this area, sinus augmentation is often needed to provide sufficient bone volume to support implants and allow prosthetic loading with predictable long-term results. Use of surgical guides for implant placement and sinus augmentation aids the practitioner in providing precision treatment. This article will discuss a method for fabrication of a surgical guide to transfer CBCT information intraorally to enable creation of a precisely placed lateral sinus window.
锥形束计算机断层扫描（CBCT）用于种植治疗计划，以帮助确定可用骨的体积并识别解剖结构。这有助于提高治疗计划的准确性，特别是当由于上颌窦下缘靠近牙槽嵴顶骨而导致上颌后牙区骨量不足时。为了将牙种植体植入该区域，通常需要进行上颌窦提升术，以提供足够的骨量来支持种植体，并实现可预测的长期效果的修复体加载。使用手术导板进行种植体植入和上颌窦提升术有助于医生提供精确的治疗。本文将讨论一种制作手术导板的方法，该导板可将CBCT信息在口腔内进行传递，以创建精确放置的外侧上颌窦开窗。
