A digital technique is described for designing and fabricating segmental individual tooth trays that can be used to make an impression of multiple preparations with high accuracy and efficiency. A digital model of prepared dentition was acquired. The segmental individual tooth trays with retention attachments and tissue stops were designed and 3D printed with light-polymerizing resin. The segmental impression of each section of the prepared dentition was made with the corresponding individual tooth tray loaded with the impression material. A final overall impression was made to pick up the segmental individual tooth trays with a full arch tray.
介绍了一种用于设计和制作分段个别牙托盘的数字技术，该技术可用于高精度、高效率地获取多个预备体的印模。通过获取预备牙列的数字模型，设计带有固位附件和组织堤的分段个别牙托盘，并使用光聚合树脂进行 3D 打印。使用装载有印模材料的相应个别牙托盘对预备牙列的每个区段进行分段印模。最后使用全牙弓托盘获取分段个别牙托盘的最终整体印模。
