PURPOSE
This article describes the protocol of a digital impression technique to make an impression and recording of the jaw relationship of edentulous patients for the fabrication of CAD/CAM custom tray using computer-aided design and manufacturing (CAD/CAM) technology.
METHODS
Scan the maxillary and mandibular edentulous jaws using an intraoral scanner. Scan the silicone jig with the maxillary and mandibular jaws while keeping the jig between the jaws. Import the standard tessellation language data of the maxillary and mandibular jaws and jig to make a jaw relation record and fabricate custom trays (CAD/CAM trays) using a rapid prototyping system. Make a definitive impression of the maxillary and mandibular jaws using the CAD/CAM trays.
CONCLUSIONS
Digitalization of the complete denture fabrication process can simplify the complicated treatment and laboratory process of conventional methods In addition, the proposed method enables quality control regardless of the operator's experience and technique.
目的
本文描述了一种数字化印模技术的方案，该技术用于获取无牙颌患者的颌关系记录，以使用计算机辅助设计和制造 (CAD/CAM) 技术制作 CAD/CAM 定制托盘。
方法
使用口内扫描仪扫描上颌和下颌无牙颌。在保持上下颌之间有硅橡胶保持架的情况下，扫描上颌和下颌的硅橡胶保持架。将上颌和下颌以及保持架的标准 tessellation language 数据导入，以制作颌关系记录，并使用快速原型制作系统制作定制托盘 (CAD/CAM 托盘)。使用 CAD/CAM 托盘对上颌和下颌进行最终印模。
结论
全口义齿制作过程的数字化可以简化传统方法复杂的治疗和实验室过程。此外，该方法可以实现质量控制，而不受操作人员经验和技术的影响。
