What does “Denture rebase” mean?
Rebasing replaces the denture base that contacts the gums while retaining the existing artificial teeth. It differs from relining, which adds material to the inner surface.
When will it be reviewed?
Rebasing may be considered when the base material is damaged or the fit has changed. If the artificial teeth are also worn or the bite is poor, the dentist assesses whether a new denture is needed instead of replacing only the base.
What do you check first?
Check the holding power, degree of contact with the gums, support, engagement, pronunciation, and appearance. Do not decide to rebase based solely on the symptom of looseness.
How does rebasing differ from relining?
Relining mainly adds new material to the tissue-facing surface, whereas rebasing replaces the base material. If the terms are used interchangeably, clarify exactly which part will be changed.
Frequently Asked Questions
Can old dentures be rebased and continue to be used?
The artificial teeth, occlusion, and overall structure must be appropriate. If there is significant wear or repeated fracture, comparisons are made, including remanufacturing.
Can I add lining material to my denture at home?
Avoid arbitrary deformation as it may incorrectly change the bite and gum pressure. Your gums and dentures will be examined together at the dentist.
