Customized cast orientations and parameter settings of the virtual articulator according to the patient's condyles are indispensable parts of today's digital workflows in prosthodontics. This article describes a digital technique to align the intraoral scans to a virtual articulator by using a facial scanner to locate the patient's cutaneous landmarks of the arbitrary hinge axis and the reference plane, and to customize the sagittal condylar inclination of the virtual articulator through a digital protrusive interocclusal record and a dental computer-aided design software program. It enables individual cast orientations and virtual articulator parameter settings without conventional facebow transferring and bite registration procedures and can be easily integrated with most virtual articulator systems on the market to allow clinicians and technicians to work in a complete digital workflow and facilitate customized treatment planning and dental prosthesis fabrication.
根据患者髁突定制虚拟牙合架的模型方向和参数设置是当今口腔修复数字化工作流程中不可或缺的部分。本文介绍了一种数字技术，通过使用面部扫描仪定位患者任意铰链轴和参考平面的皮肤标志点，将口内扫描数据与虚拟牙合架对齐，并通过数字前伸牙合记录和牙科计算机辅助设计软件程序定制虚拟牙合架的矢状髁突倾斜度。它无需传统的面弓转移和咬合记录程序即可实现个性化的模型方向和虚拟牙合架参数设置，并且可以轻松地与市场上的大多数虚拟牙合架系统集成，使临床医生和技术人员能够在完整的数字化工作流程中工作，便于进行个性化的治疗计划和义齿制作。
