This article introduces a digital technique for virtual articulator mounting by employing the scan of a facebow worn by the patient as a virtual reference. The digital technique enables the transfer of the maxillary arch orientation relative to the cranial base into a CAD-CAM environment (Ceramill Mind; AmannGirrbach), without the need for ionizing radiation or identification of facial landmarks. By digitally aligning the intraoral scans of the dental arches (Trios 4; 3Shape) with a 3D facial scan and the scanned facebow in position (Artex; AmannGirrbach), clinicians can reproduce the cranium-to-maxilla spatial relationship accurately and intuitively. This radiation-free protocol provides virtual cross-mounting and allows for the use of a semi-adjustable articulator within common CAD-CAM software. Given that intraoral scanners, facial scanners, and design software with articulator simulation are becoming more available in modern clinical workflows, this method introduced here could be a viable radiation-free and easy-to-use alternative. However, larger cohorts and standardized testing protocols are needed to determine its clinical reproducibility and reliability.
本文介绍了一种数字技术,通过将患者佩戴的面弓扫描作为虚拟参考来进行虚拟牙合架安装。该数字技术能够将上颌牙弓相对于颅底的方位转移到计算机辅助设计与制造(CAD-CAM)环境(Ceramill Mind;阿曼吉尔巴赫公司)中,无需电离辐射或面部标志点的识别。通过将牙弓的口内扫描(Trios 4;3Shape公司)与三维面部扫描以及处于就位状态的扫描面弓(Artex;阿曼吉尔巴赫公司)进行数字对齐,临床医生能够准确且直观地重现从颅骨到上颌的空间关系。这种无辐射方案提供了虚拟交叉安装功能,并允许在常见的CAD-CAM软件中使用半可调牙合架。鉴于口内扫描仪、面部扫描仪以及具有牙合架模拟功能的设计软件在现代临床工作流程中越来越普及,此处介绍的这种方法可能是一种可行的无辐射且易于使用的替代方案。然而,需要更大规模的队列研究和标准化测试方案来确定其临床可重复性和可靠性。
