Watch the short video and learn how this works.
In this second part we will describe how to create the dynamic cut on the occlusion of the lower crown. At this stage ensure the articulator animation is fully functional. This was described in the previous part. You would have then followed the general procedure for making a crown. These involved placing all relevant objects into their collections, surfaces have been constructed, surveyed and blocked out, and the all contact areas have been selected and turned pink. The support margin is now also in place. Under static occlusal adjustments you would now follow the Occlusal Adjustment submenu, as was previously described. The workflow deviates away from this submenu since we will perform the dynamic cut within the articulator module.
Before crossing into the articulator menu, you may want to still change the height of the crown. By pressing the T key, you can access the directional widget, then use the arrow to position the vertical height of the crown. If you have an open scan, you can view the occlusal surface of the crown as it penetrates through the mesh of the antagonist. If you want to add to the anatomy of the crown, simply use the 'Inflate/Deflate Selected' button.
In the Articulator module first view animation in the 'Articulator Navigation' submenu. Use any of the buttons, for example, View Left. It is very important here to link all objects relevant to a lower scan/model to the animation as well. Select the crown, then press the 'Link Object to Animation' button in the Articulator Cutting Tools submenu.
Again test the animation to make sure the lower crown is also animated.
Select the Antagonist, and press the 'Object Making Cut' button. Set a small offset to this depending on the bite requirements. For example, no occlusal bite contact, light contact or no contact. Apply the offset, the cutting tool will turn translucent grey in colour.
Select the crown next and press the 'Object Being Cut' button.
Use the playhead on the timeline slider to select the area you wish to cut, the 'Apply Single Cut'. This can be done for any Keyframe.
In order to create a dynamic occlusal adjustment which uses all of the Blender keyframes, press the 'Cut All Movements' button.
After the adjustment has been made press the 'Delete Object Making Cut' button. Close the timeline.
Enter back into the Crown module, press 'Click To Finish This Stage' in the Occlusal Adjustment submenu, then continue designing the crown as usual by entering into the Generating Crowns submenu.
