Abstract：
The unique anatomical structure of the atrophic edentulous maxilla limits the placement of endosteal root form dental implants without bone grafting and augmentation. Surgical placement of zygomatic implants in an optimal position remains challenging. This technique report illustrates a novel digital guide technology, including the design workflow, application method, and indications for assisting with the placement of zygomatic implants using a bone-supported titanium double-sleeve guide. In addition, when the implant body reaches the zygomatic bone following an intra-sinus path, including ZAGA type 0 and ZAGA type 1 cases, a matching window osteotomy surgical guide is used to locate the lateral window boundary and protect the sinus membrane. With this technique, the surgical procedure is simplified, and the precision of guided zygomatic implant placement is improved.
摘要：
萎缩性无牙颌上颌骨的独特解剖结构限制了内骨根形牙植入物的放置，而无需植骨和增强。在最佳位置中手术放置zy骨植入物仍然具有挑战性。该技术报告说明了一种新颖的数字指南技术，包括设计工作流程，应用方法，以及使用骨支撑钛双套管导向器协助放置zy骨植入物的适应症。此外,当植入物主体沿着窦内路径到达颧骨时，包括ZAGA0型和ZAGA1型病例，匹配的开窗截骨手术导向用于定位外侧窗口边界并保护窦膜。有了这项技术,简化了手术过程，并提高了骨引导植入的精度。本文受版权保护。保留所有权利。
