This report describes a digital workflow for the fabrication of a complete maxillary denture opposing an implant-retained overdenture. This procedure provides a predictable and accurate 3-visit technique to digitally scan and articulate edentulous ridges, avoiding the discomfort associated with analog impression making. Wax rims were applied to intraorally relined plastic edentulous stock trays. The occlusal relationship was registered at the appropriate vertical dimension of occlusion by using these tray and rim assemblies. The digital laboratory scanning of the relined tray and rim assemblies resulted in accurate virtual articulation of the digital edentulous intraoral scans. The removable restorations were digitally designed, milled, and delivered, and the clinical and laboratory steps are described.
本报告介绍了一种数字化工作流程，用于制作与种植体固位覆盖义齿相对应的全上颌义齿。该程序提供了一种可预测且准确的 3 次就诊技术，可对无牙颌牙槽嵴进行数字化扫描和咬合，避免了与传统印模制作相关的不适。蜡边缘被应用于口内重新衬里的塑料无牙托盘中。通过使用这些托盘和边缘组件，将咬合关系记录在适当的垂直咬合高度上。数字化实验室对重新衬里的托盘和边缘组件进行扫描，从而准确地虚拟咬合数字化无牙口腔扫描。可摘修复体被数字化设计、铣削和交付，并且描述了临床和实验室步骤。
