目的是建立和评估一种使用计算机辅助设计和熔融沉积建模 (FDM) 技术制造无牙颌定制托盘的方法。建立了一种用于设计无牙颌定制托盘的数字方法。使用 3D 扫描仪获得了 10 个标准下颌无牙石膏模型的组织表面数据，用于在逆向工程软件中设计数字定制托盘。设计的托盘由3D FDM 打印设备打印。另外生产了十个手工定制托盘作为对照。扫描模型和定制托盘的三维表面数据来评估预留印模空间的准确性，同时分析数字化托盘和手工托盘之间的差异。数字化制作的定制托盘与下颌模型实现了良好的匹配，比手工制作的精度更高。不同型号及其配套的数字化托盘预留空间没有显着差异。利用3D扫描、CAD和FDM技术，建立了高效的定制托盘生产方法，实现了高再现性和准确性。
The objective was to establish and evaluate a method for manufacture of custom trays for edentulous jaws using computer aided design and fused deposition modeling (FDM) technologies. A digital method for design the custom trays for edentulous jaws was established. The tissue surface data of ten standard mandibular edentulous plaster models, which was used to design the digital custom tray in a reverse engineering software, were obtained using a 3D scanner. The designed tray was printed by a 3D FDM printing device. Another ten hand-made custom trays were produced as control. The 3-dimentional surface data of models and custom trays was scanned to evaluate the accuracy of reserved impression space, while the difference between digitally made trays and hand-made trays were analyzed. The digitally made custom trays achieved a good matching with the mandibular model, showing higher accuracy than the hand-made ones. There was no significant difference of the reserved space between different models and its matched digitally made trays. With 3D scanning, CAD and FDM technology, an efficient method of custom tray production was established, which achieved a high reproducibility and accuracy.
