This article describes a complete digital workflow for importing intraoral scan data and jaw motion data from Shining3D into exocad, and applying dynamic mandibular movement data in the design of a single crown. The maxillary right lateral incisor (FDI 12) is used as an example. For detailed operational procedures, please refer to the YouTube video above.
Steps:
1. Launch exocad DentalCAD
2. Load Data from Shining3D
1）Import the intraoral data exported from Shining3D with the .dentalProject file format.
2）Complete the case setup, including tooth selection and restoration type.
3. Load Jaw Motion Data
1）In the design interface, select Load jaw movement data from file in the Virtual Articulator window on the left side.
2）From the pop-up window, select the exported jaw motion file.
4. Select and Evaluate Mandibular Movements
1）Select the desired mandibular movement from the drop-down list.
2）Drag the threshold slider to visualize and evaluate the range and direction of mandibular motion, and observe the dynamic movement of the lower jaw relative to the maxillary arch.
5. Apply Jaw Movement During Crown DesignJaw motion data can be applied throughout the crown design process. The following steps illustrate the workflow using tooth 12 (maxillary right lateral incisor) as an example.
1）Initial Crown Generation: Generate the anatomical crown using the standard exocad workflow.
2）Removal of Lingual Occlusal Interferences: Remove occlusal interference areas located on the lingual surface of the generated crown to provide initial functional clearance.
3）Functional Adjustment Based on Jaw Motion: Activate the selected mandibular movement. Identify occlusal premature contacts during dynamic mandibular motion and remove these high points according to the movement trajectory to avoid functional interferences.
4）Generate and Adjust Virtual Imprint: Generate an overall Virtual Imprint, analyze occlusal contact distribution, and remove excessive contact areas to achieve balanced and functional occlusion.
5）Adaptive Adjustment of Occlusion and Proximal Contacts: Fine-tune the crown’s proximal contacts to ensure proper functional adaptation, contact strength, and clinical fit.
6）Final Check and Output: Re-evaluate the crown under dynamic jaw movements, confirm that no interferences occur during functional excursions, finalize the crown design, and proceed with manufacturing.
