Pronounced defects of the dental hard tissue can be caused by different etiologic factors. Most frequently, they are associated with changes in the vertical dimension of occlusion (VDO), which may also influence the condylar positions. These defects can lead to irreversible loss of tooth structure and have dramatic functional and esthetic consequences, often requiring complex rehabilitation. In this situation, CAD/CAM-fabricated occlusal splints made of tooth-colored polycarbonate are a proven and safe pretreatment approach in terms of esthetics and function. Rebuilding lost dental hard tissue to restore the occlusion and VDO to an adequate condylar position is a prerequisite for any sustainable and functional rehabilitation. In the future, digital systems will support this complex process, customizing it and making it simpler and more precise. The DMD-System (Ignident) provides patient-specific jaw movement data to optimize the CAD/CAM workflow. This system allows real movement patterns to be digitized and analyzed for functional and potential therapeutic purposes, integrating them into the dental and laboratory workflow. In the present case, the familiar tooth-colored CAD/CAM-fabricated occlusal splint is supplemented by digital centric jaw relation recording and individual movement data.
牙齿硬组织的明显缺陷可能由不同的病因引起。这些缺陷最常与咬合垂直距离（vertical dimension of occlusion，VDO）的变化有关，VDO 的改变也可能影响髁突位置。这些缺陷会导致牙齿结构不可逆的丧失，并产生显著的功能和美观后果，通常需要复杂的修复。在这种情况下，由牙色聚碳酸酯制成的 CAD/CAM 制作的咬合垫在美观和功能方面是一种经过验证且安全的预处理方法。重建缺失的牙体硬组织，以将咬合和 VDO 恢复到适当的髁突位置，是任何可持续和功能性修复的前提。未来，数字化系统将支持这一复杂的过程，使其更加简化和精确。DMD 系统（Ignident）提供患者特定的下颌运动数据，以优化 CAD/CAM 工作流程。该系统允许对真实的运动模式进行数字化和分析，以达到功能和潜在治疗的目的，并将其整合到牙科和实验室工作流程中。在本例中，传统的牙色 CAD/CAM 制作的咬合垫通过数字化的颌位关系记录和个体化的运动数据得到了补充。
