Computer-aided design and computer-aided manufacturing (CAD-CAM) technologies have been successfully integrated into the digital workflow to treat completely edentulous patients. However, the digital design and manufacturing technique of the baseplate and occlusion rims have not yet been developed into the digital workflow. This article describes a novel digital workflow using extraoral digitizing procedures, open-source CAD software, and additive manufacturing technologies to obtain a 3D patient. This virtual patient can then be used to plan treatment for a completely edentulous patient, with which the maxillary baseplate and occlusion rims are digitally designed. The workflow allows the digital determination of tooth exposure at rest, the dental midline, the location of the canines, and the determination of the occlusal plane related to the Camper plane. The digital determination of these parameters increases the predictability of the treatment, reducing laboratory and clinician time and costs.
计算机辅助设计和计算机辅助制造（CAD-CAM）技术已成功整合到数字化工作流程中，用于治疗完全无牙患者。然而，基托和咬合边缘的数字化设计和制造技术尚未纳入数字化工作流程。本文介绍了一种使用口外数字化程序、开源 CAD 软件和增材制造技术获得 3D 患者的新型数字化工作流程。然后，可使用该虚拟患者来规划完全无牙患者的治疗，其中上颌基托和咬合边缘进行数字化设计。该工作流程允许在休息时、牙中线、尖牙位置以及与 Camper 平面相关的咬合平面等方面进行牙齿暴露的数字确定。这些参数的数字化确定提高了治疗的可预测性，减少了实验室和临床医生的时间和成本。
