This study explored a method for fabricating removable complete denture aided by CAD&RP technology. 3D crossing section scanner and laser scanner were respectively applied to obtain the surface data of artificial teeth, edentulous models and rims made in clinic. The vertical and horizontal relations of models were recorded before scanning with a special device. A 3D graphic database of artificial teeth, which can be aligned with parameters, was established. Special CAD software developed by ourselves was applied to the 3D integrated design process including automatic setting up artificial teeth, semiautomatic designing aesthetic and individualized artificial gingiva and base plate, automatic constructing individualized virtual flasks according to the finished CAD digital models of removable complete denture. At last, 3DP technology was used to make the individualized physical flasks. In this study, AMT and classic denture materials were effectually combined to achieve making removable complete denture aided by CAD/RP technology.
本研究探索了一种借助CAD&RP技术制作可摘全口义齿的方法。分别应用三维断面扫描仪和激光扫描仪获取临床制作的人工牙、无牙颌模型及基托边缘的表面数据。扫描前用专用装置记录模型的垂直和水平关系。建立了可与参数对齐的人工牙三维图形数据库。应用自行开发的专用CAD软件进行三维一体化设计，包括自动排牙、半自动设计美观且个性化的人工牙龈和基托，根据完成的可摘全口义齿CAD数字模型自动构建个性化虚拟型盒。最后，采用3DP技术制作个性化实体型盒。本研究有效地将AMT与经典义齿材料相结合，实现了借助CAD/RP技术制作可摘全口义齿。
