A 91-year-old woman was referred to our hospital with a chief complaint of unsatisfactory fit and pain associated with her complete dentures. She had moderate dementia with difficulty in communication (Mini-Mental State Examination, 16; Barthel Index, 15). The closed impressions and jaw record were taken with the digitally fabricated copy dentures as follows. First, the tissue conditioner was used to correct the poor fit of the old dentures, following which minor occlusal alterations were made. Second, the copy dentures that copied the morphology of the corrected old dentures using three-dimensional (3D) scanner were fabricated with a 3D printer. The new dentures were then fabricated using conventional methods as follows. The impressions were cast and articulated, and the dentures were subsequently processed. This case report documented the following results. First, the acceptance of new dentures appeared to be easier since the new dentures copied the morphology of the familiar dentures digitally. Moreover, the 3D data of the dentures could be used for immediate denture fabrication in case of fracture or loss of the dentures. Second, only two visits were required for taking an impression and delivering the complete dentures. In addition, her old dentures were brought to our dental office by the patient's family after the patient's dinner; immediately after copying the dentures' morphology, the dentures were returned to the patient's family, thus avoiding any disturbance to the patient's eating routine. These reduced the burden on the patient and her family.
一名91岁女性因全口义齿佩戴不适和疼痛前来我院就诊。她患有中度痴呆，沟通困难（简易精神状态检查表评分为16分；巴氏指数为15分）。采用数字化制作的复制义齿进行闭口印模和颌位记录，具体如下。首先，使用组织调整剂纠正旧义齿的贴合不良问题，随后进行轻微的咬合调整。其次，使用三维（3D）扫描仪复制已矫正旧义齿形态的复制义齿，并用3D打印机制作。然后采用传统方法制作新义齿，具体如下。取印模、灌模并上合架，随后制作义齿。本病例报告记录了以下结果。第一，由于新义齿通过数字化方式复制了患者熟悉的义齿形态，患者似乎更容易接受新义齿。此外，义齿的3D数据可用于义齿折断或丢失时的即刻义齿制作。第二，取印模和交付全口义齿仅需就诊两次。此外，患者家属在患者晚餐后将其旧义齿带到我们的牙科诊所；在复制义齿形态后，义齿立即归还给患者家属，从而避免了对患者饮食习惯的任何干扰。这些措施减轻了患者及其家属的负担。
