The demand for complete dentures is expected to increase worldwide, but complete dentures are mainly designed and fabricated manually involving a broad series of clinical and laboratory procedures. Therefore, the quality of complete dentures largely depends on the skills of the dentist and technician, leading to difficulty in quality control. Computer-aided design and manufacturing (CAD/CAM) has been used to design and fabricate various dental restorations including dental inlays, veneers, crowns, partial crowns, and fixed partial dentures (FPDs). It has been envisioned that the application of CAD/CAM technology could reduce intensive clinical/laboratory work for the fabrication of complete dentures; however, CAD/CAM is seldom used to fabricate complete dentures due to the lack of suitable CAD software to design virtual complete dentures although the CAM techniques are in a much advanced stage. Here we report the successful design of virtual complete dentures using CAD software of 3Shape Dental System 2012, which was developed for designing fixed prostheses instead of complete dentures. Our results demonstrated that complete dentures could be successfully designed by the combination of two modeling processes, single coping and full anatomical FPD, available in the 3Shape Dental System 2012.
全球范围内对全口义齿的需求预计将会增加，但全口义齿主要是通过手工设计和制作的，涉及广泛的临床和实验室程序。因此，全口义齿的质量在很大程度上取决于牙医和技师的技能，这导致质量控制困难。计算机辅助设计和制造（CAD/CAM）已被用于设计和制作各种牙科修复体，包括牙嵌体、贴面、牙冠、部分冠和固定局部义齿（FPD）。人们设想 CAD/CAM 技术的应用可以减少全口义齿制作过程中的密集临床/实验室工作；然而，由于缺乏适合设计虚拟全口义齿的 CAD 软件，尽管 CAM 技术已经处于非常先进的阶段，但 CAD/CAM 很少用于制作全口义齿。在这里，我们报告了使用 3Shape Dental System 2012 的 CAD 软件成功设计虚拟全口义齿的情况，该软件是为设计固定修复体而不是全口义齿而开发的。我们的结果表明，通过 3Shape Dental System 2012 中提供的两种建模过程，即单冠和全解剖 FPD 的组合，可以成功设计全口义齿。
