Bite splint antagonist/adjacent adaptation
To adjust the occlusion of the bite splint, see Adaptation to antagonists / approximal adaptation. It is helpful to use the "Distance to antagonist" tool to observe the effect of the adaptation - see section Visualizing intersections/distance to antagonists or anteriors for details on how to enable and use the color visualization.
With the antagonist distance visualization enabled, the colors on the bitesplint are indications of the intersections between the bite splint and opposing model / antagonist.
In the next step of the wizard, you will be able to freeform the Bitesplint top - as desribed in the documentation of the "Free" tab in Freeforming.
