A technique to additively manufacture an occlusal device by using a completely digital workflow is described. Using a computer-aided design program, information captured with an intraoral scanner was used to additively manufacture a dual-material occlusal device by using a vat-polymerization printer. This technique allows for the combination of 2 different materials, resulting in an occlusal device with a resilient intaglio and a hard resin exterior surface. Advantages of the resulting occlusal device compared with a single-material device include improved patient acceptance and comfort, better fit, and minimal adjustments to ensure fit.

一种还原聚合的 3 维打印双材料咬合装置：一种牙科技术

描述了一种通过使用完全数字化的工作流程来增材制造咬合装置的技术。使用计算机辅助设计程序，使用口腔内扫描仪捕获的信息通过使用还原聚合打印机来增材制造双材料咬合装置。这种技术允许结合 2 种不同的材料，从而形成具有弹性凹版和硬树脂外表面的咬合装置。与单一材料装置相比，所得到的咬合装置的优点包括提高了患者的接受度和舒适度、更好的贴合性以及最少的调整以确保贴合。
