Colour intraoral scans of edentulous arches show you something a monochrome scan throws away: the line between attached mucosa and movable lining mucosa — the border that decides how far a denture fl**ge should extend.
Extend into the attached, supporting zone and the functional sulcus; stopping short of the movable tissue that displaces the denture. It won't replace functional border moulding, but reading it before you design means fewer over-extensions and fewer adjustment visits.
Save this for your next full-arch scan — and send it to a colleague who's chasing better border seal on an upper so they don't drop down as easily.
