Abstract

A technique to improve the accuracy of complete arch implant intraoral digital scans and to obtain more accurate virtual casts with them is described. First, 2 complete arch intraoral digital scans were obtained with an intraoral scanner: a multiunit abutment digital scan and an implant digital scan with reusable horizontal intraoral scan bodies (ISBs) placed on the implants. These were previously created by combining the conventional ISBs compatible with the patient’s implants with extensional structures with occlusal geometry. Once the digital scans had been acquired, the position of the implants was obtained by superimposing a virtual design of the conventional ISB onto each horizontal ISB of the complete arch implant digital scan. Finally, the virtual cast was obtained by superimposing the complete arch multiunit abutment digital scan on the complete arch implant digital scan.

通过使用具有咬合几何形状的水平扫描体提高全牙弓种植体口内数字扫描的准确性：牙科技术。

本文介绍了一种提高全牙弓种植体口内数字扫描精确度并获得更精确虚拟铸模的技术。首先，使用口内扫描仪获得 2 个完整的牙弓口内数字扫描：一个多单位基台数字扫描和一个种植体数字扫描，在种植体上放置了可重复使用的水平口内扫描体（ISB）。这些扫描体之前是通过将与患者种植体相匹配的传统 ISB 与具有咬合几何形状的扩展结构相结合而创建的。数字扫描完成后，通过将传统 ISB 的虚拟设计叠加到全牙弓种植体数字扫描的每个水平 ISB 上，获得种植体的位置。最后，通过将全牙弓多单位基台数字扫描叠加到全牙弓种植体数字扫描上，获得虚拟铸造体。
