Rebasing is usually done when the denture teeth have not worn out in
comparison to the denture base material. It is a process of retrofitting dentures by replacing all of the acrylic denture
base with new acrylic, which provides a stable denture without replacing the denture teeth.
Duplicate Dentures are exact copies of your current dentures and are only used in emergencies i.e. you've
lost or broken your main pairs.
