The integration of digital dentistry in the fabrication of complete dentures (CDs) has been facilitated through the use of intraoral scanners and computer-aided design and manufacturing (CAD/CAM). However, the financial implications associated with the fabrication of digital CDs have been rarely explored. This study is aimed at presenting two different approaches to CD fabrication, combining conventional with digital techniques, and comparing the total cost of fabrication. The first case involved a 70-year-old woman without existing denture, while the second case involved a 97-year-old woman with inadequate retention and stability of CDs in both jaws. In the first patient, who lacked information about her old denture, the first approach was employed, utilizing milling technology for denture processing. The second patient, who already had an existing denture, underwent the second approach, which employed printing technology for denture processing. CAD/CAM replicas of the existing dentures were used for the final impression, bite registration, and as a guide for tooth arrangement. Two digital protocols and laboratory cost in CD fabrication have been proposed. The relatively high cost of CAD/CAM CDs restricts the widespread of digital technology in CD fabrication.
通过使用口内扫描仪以及计算机辅助设计与制造（CAD/CAM）技术，数字牙科已助力全口义齿（CD）的制作。然而，与数字全口义齿制作相关的财务影响却鲜有探讨。本研究旨在介绍两种不同的全口义齿制作方法，即将传统技术与数字技术相结合，并比较制作总成本。第一个病例是一名70岁无现有义齿的女性，而第二个病例是一名97岁的女性，其上下颌全口义齿的固位和稳定性不足。在第一个缺乏旧义齿信息的患者中，采用了第一种方法，利用铣削技术进行义齿加工。第二个已有现有义齿的患者采用了第二种方法，即采用打印技术进行义齿加工。现有义齿的CAD/CAM复制品用于最终印模、咬合记录，并作为排牙的指导。本文提出了两种全口义齿制作的数字方案及实验室成本。CAD/CAM全口义齿相对较高的成本限制了数字技术在全口义齿制作中的广泛应用。
