Relines are required when bone and tissues change due to resorption (shrinkage).
Possible causes may be:
- Post immediate dentures
- Tooth loss
- Weight loss
- Bone loss in the upper or lower jaw
- Sickness or disease
- General physiological aging
Your denturist will assess if it is in your best interest to make new dentures or reline your existing dentures as an interim measure.
There are some procedures to improve the fit of your dentures temporarily.
Relining dentures is generally necessary when full (removable) dentures become loose, after years of wear.
The rate of bone loss differs from person to person; some denture wearers may need more frequent relines than others.
Upper dentures tend to fit better and be less problematic than lower dentures because they have a much larger surface area on which to suction and rest.
For a reline procedure, the existing teeth, bite position and acrylic base(s) must be in
good condition and not worn or stained.
This consists of adding new acrylic base material to the tissue side of a denture so it
Our denturist will need to take an impression inside your existing denture to
use as a working model.
Relining affects only the fit of your denture and will not change the appearance.
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.
The procedure is similar to relining but a rebase replaces all of the pink denture base
with new acrylic, which provides a stable denture without replacing the denture teeth.
Reasons for a rebase procedure:
- Broken denture
- Weakened or old pink denture base
- Immediate denture
