Abstract
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.

After registering the tissue surface of FDM printed custom tray to its computer-aided design (CAD) data in the Geomagic software, the deviation between them was analyzed in Imageware
Combining 3D data acquisition with CAD/computer-aided manufacture (CAM) techniques, this study explored a digital methodology for the production of custom trays for edentulous jaw
Summary
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 stock impression tray, rarely matches the shape of a patient’s alveolar and dental arch This technique cannot guarantee an appropriate extension of the denture border or uniform thickness of the impression material and is, seldom used in patients[7]. Method, the secondary impression method allows for production of a tray that fits well and makes an accurate impression of the patient’s jaws[8,9] This technique takes extra time and materials, and the deformation of wax when paving onto the cast often leads to non-uniform space for the final impression material
