Relines, Rebase and Repairs

Rebase
Rebasing is often done when a denture's base becomes worn out before its teeth. It involves replacing the old acrylic denture base material with a new one. As a result, this provides a new stable base, without having to replace the denture teeth.
 
Relines
The purpose of a reline is to improve the fit of your denture. A reline is ideal when a denture becomes loose or when it is irritating your gums. Thus, a reline helps to a make a denture more comfortable to wear.
Relines are often needed as a result of your jaw tissues changing, such as becoming smaller. This process is known as "resorption" and can happen over a period of months to years.
Resorption can happen for a number of reasons including:
  • Weight loss
  • Tooth loss
  • Bone loss
  • Aging
  • Disease
  • Illness
Keep in mind that relining only affects the fit of the denture and doesn’t change anything else about it.
There are two types of relines: hard and soft:

Soft Reline
Soft relines are ideal when the patient has sensitive gum tissues or when there are sore spots. The main difference between a soft reline and hard reline is the material used. Soft relines use a softer, porous material inside the dentures to provide added comfort for sore gums. However, soft relines require more regular adjustments compared to hard relines.
 
Repairs
More often than not, your denturist will be able to restore your damaged dentures to its original state. A denture may need to be repaired due to breakage, chipping, wear and tear, or when additional teeth need to be added.
Some repairs need an impression reline in conjunction with repair. Never try to fix the denture yourself or use glue.
Most repairs can be completed within a day. If your denture is in need of a repair, it may indicate other underlying problems, such as old age, worn teeth or a poor fit.  Your denturist can help you keep your denture in good shape.
