That info could be significant. The effects of jaw movement have been
well established in regard to CIC fits. Sometimes that can be addressed
by using the "open jaw" impression technique, having the user keep a
dental dam between the teeth while the impression material is injected.
That helps compensate for any wide range of movement that could cause
shifting of the aid.
