What does “Denture rebase” mean?
Rebasing replaces the material forming a denture's base while retaining its artificial teeth. It should be distinguished from relining, which resurfaces the tissue-facing side, by confirming what will actually be changed.
Can the existing denture teeth be retained?
Because rebasing reuses the artificial teeth, their wear, arrangement, and bite must first be assessed. If problems cannot be addressed by changing the base alone, a new denture may need to be considered.
Distinguishing a lining change from a base replacement
Relining adds new material to the denture's inner surface, whereas rebasing replaces the base. When discussing treatment, ask whether material is being added to the tissue-facing surface or the base itself is being replaced, rather than relying on an imprecise term.
Check the bite and gums after treatment
Denture stability depends on the bite and surrounding tissues as well as base adaptation. After treatment, pressure spots and unwanted movement should be checked. Have the denture's problems assessed professionally rather than adding material yourself.
Frequently Asked Questions
Are rebasing and relining exactly the same?
No. Relining adds material to the tissue-facing surface, while rebasing replaces the denture base material. Confirm the actual scope of the proposed procedure.
Will rebasing solve every loose denture?
No. Bite problems, worn artificial teeth, or issues with the design may not be corrected by relining or rebasing alone. Making a new denture may be considered.
